                                          OPINION

SMITH, Senior Judge:

        Respondent seeks review of an entitlement decision issued by Special Master Brian H.
Corcoran, granting petitioner, Carmen Lozano’s, petition for vaccine injury compensation.
Petitioner brought this action pursuant to the National Vaccine Injury Compensation Program, 42
U.S.C. §§ 300aa-10–34 (2012) (“Vaccine Act”), alleging that she developed acute disseminated
encephalomyelitis (“ADEM”) due to receipt of the tetanus-diphtheria-acellular-pertussis
(“Tdap”) vaccine on June 15, 2012. The Special Master awarded compensation, finding that
petitioner carried her burden establishing causation. Lozano v. Sec’y of Health & Human Servs.,
2017 SW 3811124 (Fed. Cl. Spec. Mstr. Aug. 4, 2017) (Lozano). Respondent now moves for
review of this decision. For the reasons that follow, the Court denies its motion.

1
        An unredacted version of this opinion was issued under seal on May 21, 2019. The
parties were given an opportunity to propose redactions, but no such proposals were made.
Nevertheless, the court has incorporated some minor changes into this opinion.
    I.      BACKGROUND

         A brief recitation of the facts provides necessary context.2

        Petitioner’s medical history prior to vaccination shows that she was largely healthy, but
that she was pregnant just before she received the vaccine at issue. Prior to and during her
pregnancy, Mrs. Lozano exhibited some symptoms that were relevant to those at issue
post-vaccination. In February of 2012, during her pregnancy, petitioner reported some bilateral
numbness in her fingers and arms. Her family further reported that Mrs. Lozano experienced an
episode of eye drooping and, on one occasion, experienced difficulty opening a jar prior to her
pregnancy. Neither of these instances were addressed in contemporary medical records.

        On July 14, 2012, Mrs. Lozano gave birth at Community Memorial Hospital (“CMH”) in
Ventura, California. On July 15, 2012, while she was still in the hospital, petitioner received a
Tdap vaccine.3 Two weeks later, on July 30, 2012, petitioner reported to Ventura County
Obstetrics and Gynecology (“VCOG”), complaining of low-grade fever, body aches, and breast
tenderness, which she reported had persisted since leaving the hospital. The nurse practitioner
suspected early mastitis4 and prescribed medication. Petitioner continued to experience the same
persistent symptoms and grew fatigued.

        On August 9, 2012, twenty-five days after vaccination, Mrs. Lozano went to the
emergency room at CMH, complaining of abdominal pain and difficulty urinating. The lab
results showed no sign of infection, so petitioner was discharged, and her symptoms were
assumed to be related to her mastitis. Her symptoms continued to worsen, and she returned to
CMH later that day, reporting increased weakness, fever, feeling off balance, vision changes,
neck pain, headache, vomiting, and dizziness. A brain MRI5 was performed and showed
“numerous focal and patchy high signal intensity lesions6 involving the brainstem,7

2
       As the basic facts here have not changed significantly, the Court’s recitation of the
background facts here draws from the Special Master’s earlier opinion in Lozano.
3
       Tdap is defined as “tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis
vaccine.” Dorland’s Illustrated Medical Dictionary 1874 (32nd ed. 2012) (“Dorland’s”).
4
       Mastitis is defined as “inflammation of the mammary gland, or breast.” Dorland’s 1111.
5
       An MRI is a “magnetic resonance imaging” exam. Dorland’s 1184.
6
       A lesion is defined as “any pathological or traumatic discontinuity of tissue or loss of
function of a part.” Dorland’s 1025.
7
       The brainstem is “the stalklike portion of the brain connecting the cerebral hemispheres
with the spinal cord and comprising the mesencephalon, pons, and medulla oblongata.”
Dorland’s 248.

cerebellopontine8 angles, right cerebellum,9 basal ganglia,10 corpus callosum11 and subcortical
white matter,”12 which suggested to the radiologist that petitioner potentially had multiple
sclerosis (“MS”),13 ADEM,14 or vasculitis.15

       Petitioner was admitted to CMH for further evaluation, including a consultation with
neurologist, Dr. Francisco Torres. Upon review of her records, Dr. Torres opined that petitioner

8
        Cerebellopontine is defined as “conducting or proceeding from the cerebellum to the
pons.” Dorland’s 332.
9
        The cerebellum is “the part of the metencephalon that occupies the posterior cranial fossa
behind the brainstem and is concerned in the coordination of movements.” Dorland’s 332.
10
        Ganglion is defined as “a knot or knotlike mass[;] anatomical terminology for a group of
nerve cell bodies located outside the ventral nervous system; occasionally applied to certain
nuclear groups within the brain.” Dorland’s 757.
11
        Corpus callosum is defined as “an arched mass of white matter, found in the depths of the
longitudinal fissure, composed of three layers of fibers, the central layer consisting primarily of
transverse fibers connecting the cerebral hemispheres.” Dorland’s 417.
12
        White matter, or substantia alba, is defined as “white substance; the white nervous tissue,
constituting the conducting portion of the brain and spinal cord; it is composed mostly of
myelinated nerve fibers arranged in anterior, posterior, and lateral funiculi in the spinal cord and
in a number of named fasciculi in the brain.” Dorland’s 1793.
13
        Multiple sclerosis is

       a disease in which there are foci of demyelination throughout the white matter of
       the central nervous system, sometimes extending into the gray matter; symptoms
       usually include weakness, incoordination, paresthesias, speech disturbances, and
       visual complaints. The course of the disease is usually prolonged, so that the term
       multiple also refers to remissions and relapses that occur over a period of many
       years.

Dorland’s 1680.
14
      Acute disseminated encephalomyelitis is

       an acute or subacute encephalomyelitis or myelitis characterized by perivascular
       lymphocyte and mononuclear cell infiltration and demyelination; it occurs most
       often after an acute viral infection, especially measles, but may occur without a
       recognizable antecedent. It is believed to be a manifestation of an autoimmune
       attack on the myelin of the central nervous system. Symptoms include fever,
       headache, and vomiting; sometimes tremor, seizures, and paralysis; and lethargy
       progressing to coma that can be fatal.

Dorland’s 613.
15
      Vasculitis is defined as “inflammation of a blood or lymph vessel.” Dorland’s 2026.

had potentially experienced an attack of MS that should be treated with Solu-Medrol16 and
physical therapy for her ambulatory problems, while petitioner awaited a more comprehensive
workup.

        Petitioner was discharged on August 13, 2012, after it was determined that steroid
treatment was helping with her symptoms. At discharge, her working diagnosis was MS, but
lumbar puncture had established that she was negative for oligoclonal bands,17 and results from
the tests that would reveal levels of myelin18 basic protein antibodies were still pending. On
August 17, 2012, Mrs. Lozano had a follow up appointment with Dr. Timothy Sheehy, who
determined that a second opinion was necessary to ensure that petitioner’s diagnosis was correct.

        On August 27, 2012, Mrs. Lozano returned to the CMH emergency room with burning in
her chest, slurred speech, hearing changes, and numbness in her tongue. She was diagnosed with
an MS flare and discharged that same day, but CMH instructed her to follow up with her primary
care physician for a second spinal MRI. That MRI was performed on August 28, 2012, and
showed “[p]atchy areas of altered signal intensity within the thoracic spinal cord . . . worrisome
for foci of demyelination.”19

       Petitioner sought a second opinion on September 9, 2012, from Dr. Barbara Giesser, a
neurologist at the University of California Los Angeles Neurology Outpatient Clinic. At that
appointment, Dr. Giesser noted that Mrs. Lozano’s current symptoms included the following:

       [N]umbness bilaterally from her chest down to her lower torso, left arm numbness
       and paresthesias,20 right arm weakness and paresthesias, right leg weakness, and
       burning around her left waist. She states that her cognition has declined and that
       she is thinking slower and forgetting objects, and having short term memory
       issues.

16
        Solu-Medrol is the “trademark for a preparation of methylprednisolone sodium
succinate.” Dorland’s 1731.
17
        Oligoclonal bands are defined as “discrete bands of immunoglobulins with decreased
electrophoretic mobility; their appearance in electrophoretograms of cerebrospinal fluid when
absent in the serum is a sign of possible multiple sclerosis or other diseases of the central
nervous system.” Dorland’s 197.
18
        Myelin is defined as “the substance of the cell membrane of Schwann cells that coils to
form the myelin sheath . . . ; it has a high proportion of lipid to protein and serves as an electrical
insulator.” Dorland’s 1218.
19
        Demyelination is defined as “destruction, removal, or loss of the myelin sheath of a nerve
or nerves.” Dorland’s 486.
20
        Paresthesia is “an abnormal touch sensation, such as burning, prickling, or formication,
often in the absence of an external stimulus.” Dorland’s 1383.

                                                 -4-
Dr. Giesser’s differential diagnosis included post-viral encephalitis/myelitis,21 22 with a working
diagnosis of “Clinically Isolated Syndrome,” and she prescribed several medications to help
improve petitioner’s ongoing symptoms.

        Throughout the fall of 2012, petitioner continued to experience the burning sensation
from her back to her chest with decreased memory, cognition, and depression. On February 13,
2013, a repeat MRI showed dramatic improvement, suggesting that ADEM was a more likely
etiology, which was confirmed through later serological23 findings. Since the winter of 2013,
doctors have continued to opine that ADEM is the most likely explanation for petitioner’s
symptoms. As such, she continues to seek treatment for the same, given that she has persistent
lingering neurological and physical impairments that keep her on disability, despite normal MRI
results. None of the medical records indicate that any of petitioner’s treatment providers doubt
her diagnosis. Additionally, Mrs. Lozano never experienced a second set of neurologic
symptoms that could reflect a flare-up of symptoms that might suggest that MS was the actual
explanation for her condition.

        Petitioner filed her Petition with the Office of Special Masters on April 13, 2014. See
generally Petition. On November 16, 2015 and June 13, 2016, petitioner filed the expert report
of Dr. Norman Latov, M.D., Ph.D.24 On March 29, 2016, respondent filed the medical report of
Dr. Thomas Leist, M.D., Ph.D.25 An entitlement hearing was held on June 24, 2017, and Special

disease process.” Dorland’s 1218.
23
       Serology is defined as

       the study of the in vitro reactions of immune sera . . . [t]he term is now used to
       refer to the use of such reactions to measure serum antibody titers in infectious
       disease (serologic tests), to the clinical correlations of the antibody titer (the

Master Corcoran granted petitioner’s claim on August 4, 2017, finding that petitioner carried her
burden establishing causation. Decision of the Special Master (hereinafter “Dec.”) at 1.
Respondent filed its Motion for Review on December 21, 2018. See generally Motion for
Review (hereinafter “MFR”). Petitioner filed its Response to respondent’s Motion for Review
on January 22, 2019. See generally Response to Respondent’s Motion for Review (hereinafter
“Resp.”). Petitioner’s Motion is fully briefed and ripe for review.

   II.     STANDARD OF REVIEW

        Under the Vaccine Act, this Court may review a special master’s decision upon the
timely request of either party. See 42 U.S.C. § 300aa-12(e)(1)–(2). In that instance, the Court
may: “(A) uphold the findings of fact and conclusions of law. . . , (B) set aside any findings of
fact or conclusion of law . . . found to be arbitrary, capricious, an abuse of discretion, or
otherwise not in accordance with law . . . , or, (C) remand the petition to the Special Master for
further action in accordance with the court’s direction.” Id. at § 300aa-12(e)(2)(A)–(C).
Findings of fact and discretionary rulings are reviewed under an “arbitrary and capricious”
standard, while legal conclusions are reviewed de novo. Munn v. Sec’y of Health & Human
Servs., 970 F.2d 863, 870 n.10 (Fed. Cir. 1992).

        This Court cannot “substitute its judgment for that of the special master merely because it
might have reached a different conclusion.” Snyder ex rel. Snyder v. Sec’y of Dep’t of Health &
Human Servs., 88 Fed. Cl. 706, 718 (2009). “Reversal is appropriate only when the special
master’s decision is arbitrary, capricious, an abuse of discretion, or not in accordance with the
law.” Id. Under this standard, a special master’s decision “must articulate a rational connection
between the facts found and the choice made.” Cucuras v. Sec’y of Dep’t of Health & Human
Servs., 26 Cl. Ct. 537, 541–42 (1992), aff’d, 993 F.2d 1525 (Fed. Cir. 1993) (citing Burlington
Truck Lines, Inc. v. United States, 371 U.S. 156, 168 (1962)). This standard is “highly
deferential.” Hines v. Sec’y of Dep’t of Health & Human Servs., 940 F.2d 1518, 1528 (Fed. Cir.
1991). “If the special master has considered the relevant evidence of record, drawn plausible
inferences and articulated a rational basis for the decision, reversible error will be extremely
difficult to demonstrate.” Id.

   III.    DISCUSSION

        Althen v. Secretary of Health & Human Services provides the evidentiary burden for
petitioners attempting to succeed in a vaccine petition based on causation. See generally Althen

and attended medical school at the University of Miami. Id. He completed a residency in
neurology at Cornell University before becoming a fellow at the National Institute of Health. Tr.
at 54. Dr. Leist is board certified in neurology and currently serves as a professor of neurology
at Thomas Jefferson University in Philadelphia, Pennsylvania, as well as directing the MS center
and guiding the MS or neuro-immunology fellowship program. Id. at 53. He sees approximately
2,700 patients diagnosed with MS, as well as seeing patients in tertiary care hospitals affiliated
with Thomas Jefferson University Hospital. Id. at 57.

                                                -6-
v. Sec’y of Health & Human Servs., 418 F.3d 1274 (Fed. Cir. 2005). In order to prove
causation-in-fact, a petitioner must

       show by preponderant evidence that the vaccination brought about [petitioner’s]
       injury by providing: (1) a medical theory causally connecting the vaccination and
       the injury; (2) a logical sequence of cause and effect showing that the vaccination
       was the reason for the injury; and (3) a showing of a proximate temporal
       relationship between vaccination and injury.

Id. at 1278. In order to succeed, petitioners must provide a “reputable medical or scientific
explanation” for their claim. Id.

         Within this framework, respondent makes two numbered objections to the August 4,
2017 decision. See MFR at 10, 13. First, respondent asserts that the Special Master erred by
failing to require evidence of a logical sequence of cause and effect showing that the vaccination
was the reason for the injury. Id. at 10. Second, respondent argues that, by finding petitioner
entitled to compensation despite her lack of evidence under Althen prong two, the Special Master
created a de facto Table claim, threatening the integrity of the Vaccine Program. Id. at 13.

       A.      Althen Prong Two

         In its Motion for Review, respondent argues that the Special Master failed to require
evidence of a logical sequence of cause and effect showing that the vaccination was the reason
for the injury. MFR at 10. In making this argument, respondent contends that “the Special
Master addressed the three prongs of Althen before determining which injury petitioner
experienced.” Id. at 11. Specifically, respondent alleges that “[i]t was not until the Special
Master turned to prong two of the Althen test that he addressed the nature of petitioner’s injury.”
Id. (citing Dec. at 16–18).

         In support of its proposition that the Special Master misapplied Althen, respondent looks
to a handful of vaccine cases from the Court of Appeals for the Federal Circuit. Respondent
cites to Lombardi v. Secretary of Health and Human Services, which states that when “the
existence and nature of the injury itself is in dispute, it is the special master’s duty to first
determine which injury was best supported by the evidence presented in the record before
applying the Althen test to determine causation of that injury.” 656 F.3d 1343, 1352 (Fed. Cir.
2011) (citation omitted). Lombardi further states that “identification of a petitioner’s injury is a
prerequisite to an Althen analysis of causation.” Id. Respondent also cites to Moberly v.
Secretary of Health and Human Services, which respondent interprets as standing for the
proposition that evidence merely showing a temporal connection between vaccination and injury
and absence of another identified cause of the injury is insufficient to demonstrate entitlement to
compensation. MFR at 12 (citing Moberly v. Sec’y of Health and Human Servs., 592 F.3d 1315
(Fed. Cir. 2010), reh’g denied, (Fed. Cir. Apr. 13, 2010)).

                                                -7-
         In response, petitioner argues that “there is no strict criteria that must be met, or
established factors that must be presented, by petitioner to establish a logical sequence of cause
and effect between vaccination and injury.” Resp. at 13. In making this argument, petitioner
cites to two of the Federal Circuit’s more seminal cases: Althen v. Secretary of Health and
Human Services and Capizzano v. Secretary of Health and Human Services. See generally
Althen, 418 F.3d 1274; see also generally Capizzano v. Sec’y of Health and Human Servs., 440
F.3d 1317 (Fed. Cir. 2006). Petitioner first looks to Althen, which states that “the purpose of the
Vaccine Act’s preponderance standard is to allow the finding of causation in a field bereft of
complete and direct proof [as to] how vaccines affect the human body.” 418 F.3d at 1280.
Petitioner also highlights the Federal Circuit’s holding in Capizzano, in which the Court
explicitly refused to establish strict criteria requiring petitioners to prove a logical sequence of
cause and effect, instead holding that petitioners cannot be required to provide scientific
evidence. 440 F.3d at 1325.

        In addition to citing Federal Circuit precedent, petitioner also looks to the decision of the
Special Master in the case at bar, arguing that the Special Master properly engaged in an Althen
analysis. As the petitioner points out, Special Master Corcoran “considered lab testing, imaging
findings[,] and [the] treating neurologist’s records as consistently supportive of a diagnosis of
ADEM.” Resp. at 15. Specifically, the Special Master found that “[p]etitioner has persuasively
established that the record evidence best supports the ADEM diagnosis.” Dec. at 16. The
Special Master then went on to weigh the evidence that supported a diagnosis other than ADEM
against the findings of Mrs. Lozano’s treatment providers, ultimately concluding that the
evidentiary record supports a finding that petitioner “established a logical sequence of cause and
effect from vaccine to injury.” Id. at 18.

         It appears to this Court that, while the Special Master may have employed a
nontraditional model in outlining his findings, the simple fact that he did not explicitly identify
ADEM as the apparent proper diagnosis until analyzing the second prong of Althen is not enough
for this Court to overturn his decision. Upon a careful review of the decision and the evidentiary
record as a whole, the Court finds that the Special Master’s decision did not violate the bounds of
his discretion, and, as such, his findings under Althen prong two were neither arbitrary nor
capricious.

       B.      De Facto Table Claim

        Respondent further argues that because the Special Master misapplied Althen, he created
a de facto Table claim, thereby threatening the integrity of the Vaccine Program. While this
Court agrees that the decision’s approach does not follow the traditional prong one, prong two,
then prong three Althen analysis, the ultimate ruling appears to be correct and the Court does not
believe the Special Master erred as a matter of law. The Office of Special Masters is overworked
and understaffed, and this Court is consistently impressed with the Special Masters’ ability to
meet deadlines and issue quality opinions. Furthermore, the Special Masters’ resilience in the
face of innumerable pressures is remarkable. As the Court remains unpersuaded by respondent’s
argument regarding the Special Master’s causation analysis, the Court does not believe a de facto

                                                -8-
Table claim was created or that a single adequate opinion has put the integrity of the Vaccine
Program at risk.

     IV.     CONCLUSION

       This Court finds that the Special Master’s decision was neither an abuse of discretion nor
contrary to law, and his findings were neither arbitrary nor capricious. For the foregoing
reasons, the Court DENIES respondent’s Motion for Review.26

           IT IS SO ORDERED.
