Myoview Perfusion Scan 
Medical specialty:  Radiology
 Resting Myoview perfusion scan and gated myocardial scan.  Findings consistent with an inferior non-transmural scar

INDICATIONS:,  Previously markedly abnormal dobutamine Myoview stress test and gated scan.,PROCEDURE DONE:,  Resting Myoview perfusion scan and gated myocardial scan.,MYOCARDIAL PERFUSION IMAGING:,  Resting myocardial perfusion SPECT imaging and gated scan were carried out with 32.6 mCi of Tc-99m Myoview.  Rest study was done and compared to previous dobutamine Myoview stress test done on Month DD, YYYY.  The lung heart ratio is 0.34.  There appears to be a moderate size inferoapical perfusion defect of moderate degree.  The gated myocardial scan revealed mild apical and distal inferoseptal hypokinesis with ejection fraction of 55%.,CONCLUSIONS:,  Study done at rest only revealed findings consistent with an inferior non-transmural scar of moderate size and moderate degree.  The left ventricular systolic function is markedly improved with much better regional wall motion of all left ventricular segments when compared to previous study done on Month DD, YYYY.  We cannot assess the presence of any reversible perfusion defects because no stress imaging was performed.

 MRI L-Spine - Bilateral lower extremity numbness

CC: ,Bilateral lower extremity numbness.,HX: ,21 y/o RHM complained of gradual onset numbness and incoordination of both lower extremities beginning approximately 11/5/96. The symptoms became maximal over a 12-24 hour period and have not changed since. The symptoms consist of tingling in the distal lower extremities approximately half way up the calf bilaterally. He noted decreased coordination of both lower extremities which he thought might be due to uncertainty as to where his feet were being placed in space. He denied bowel/bladder problems, or weakness or numbness elsewhere. Hot showers may improve his symptoms. He has suffered no recent flu-like illness. Past medical and family histories are unremarkable. He was on no medications.,EXAM:, Unremarkable except for mild distal vibratory sensation loss in the toes (R>L).,LAB:, CBC, Gen Screen, TSH, FT4, SPE, ANA were all WNL.,MRI L-SPINE:, Normal.,COURSE:, Normal exam and diminished symptoms at following visit 4/23/93.

 MRI T-spine and CXR - Aortic Dissection.

CC:, BLE weakness.,HX:, This 82y/o RHM was referred to the Neurology service by the Neurosurgery service for evaluation of acute onset paraplegia. He was in his usual state of health until 5:30PM on 4/6/95, when he developed sudden "pressure-like" epigastric discomfort associated with bilateral lower extremity weakness, SOB, lightheadedness and diaphoresis. He knelt down to the floor and "went to sleep." The Emergency Medical Service was alert and arrived within minutes, at which time he was easily aroused though unable to move or feel his lower extremities. No associated upper extremity or bulbar dysfunction was noted. He was taken to a local hospital where an INR was found to be 9.1. He was given vitamin K 15mg, and transferred to UIHC to rule out spinal epidural hemorrhage. An MRI scan of the T-spine was obtained and the preliminary reading was "normal." The Neurology service was then asked to evaluate the patient.,MEDS:, Coumadin 2mg qd, Digoxin 0.25mg qd, Prazosin 2mg qd.,PMH:, 1)HTN. 2)A-Fib on coumadin. 3)Peripheral vascular disease:s/p left Femoral-popliteal bypass (8/94) and graft thrombosis-thrombolisis (9/94). 4)Adenocarcinoma of the prostate: s/p TURP (1992).,FHX: ,unremarkable.,SHX:, Farmer, Married, no Tobacco/ETOH/illicit drug use.,EXAM:, BP165/60 HR86 RR18 34.2C SAO2 98% on room air.,MS: A&O to person, place, time.

EKG showed A-Fib at 75BPM with competing junctional pacemaker, essentially unchanged from 9/12/94.,It was suspected that the patient sustained an anterior-cervico-thoracic spinal cord infarction with resultant paraplegia and T6 sensory level. A CXR was done in the ER prior to admission. This revealed cardiomegaly and a widened mediastinum. He returned from the x-ray suite and suddenly became unresponsive and went into cardiopulmonary arrest. Resuscitative measures failed. Pericardiocentesis was unremarkable. Autopsy revealed a massive aortic dissection extending from the aortic root to the origin of the iliac arteries with extensive pericardial hematoma. The dissection was seen in retrospect on the MRI T-spine.
