 A right-handed female with longstanding intermittent right low back pain, who was involved in a motor vehicle accident with no specific injury at that time. 

HISTORY: , The patient is a 56-year-old right-handed female with longstanding intermittent right low back pain, who was involved in a motor vehicle accident in September of 2005.  At that time, she did not notice any specific injury.  Five days later, she started getting abnormal right low back pain.  At this time, it radiates into the buttocks down the posterior aspect of her thigh and into the right lateral aspect of her calf.  Symptoms are worse when sitting for any length of time, such as driving a motor vehicle.  Mild symptoms when walking for long periods of time.  Relieved by standing and lying down.  She denies any left leg symptoms or right leg weakness.  No change in bowel or bladder function.  Symptoms have slowly progressed.  She has had Medrol Dosepak and analgesics, which have not been very effective.  She underwent a spinal epidural injection, which was effective for the first few hours, but she had recurrence of the pain by the next day.  This was done four and a half weeks ago.,On examination, lower extremities strength is full and symmetric.  Straight leg raising is normal.,OBJECTIVE:,  Sensory examination is normal to all modalities.  Full range of movement of lumbosacral spine.

Medical specialty:  Radiology
 A ight-handed inpatient with longstanding history of cervical spinal stenosis status post decompression, opioid dependence, who has had longstanding low back pain radiating into the right leg.

HISTORY: , The patient is a 78-year-old right-handed inpatient with longstanding history of cervical spinal stenosis status post decompression, opioid dependence, who has had longstanding low back pain radiating into the right leg.  She was undergoing a spinal epidural injection about a month ago and had worsening of right low back pain, which radiates down into her buttocks and down to posterior aspect of her thigh into her knee.  This has required large amounts of opioid analgesics to control.  She has been basically bedridden because of this.  She was brought into hospital for further investigations.,PHYSICAL EXAMINATION: , On examination, she has positive straight leg rising on the right with severe shooting, radicular type pain with right leg movement.  Difficult to assess individual muscles, but strength is largely intact.  Sensory examination is symmetric.  Deep tendon reflexes reveal hyporeflexia in both patellae, which probably represents a cervical myelopathy from prior cord compression.  She has slightly decreased right versus left ankle reflexes.  The Babinski's are positive.  On nerve conduction studies, motor and sensory distal latencies, evoked response amplitudes, conduction velocities, and F-waves are normal in lower extremities.,NEEDLE EMG: , Needle EMG was performed on the right leg and lumbosacral paraspinal muscles using a disposable concentric needle.  It reveals the spontaneous activity in right peroneus longus and gastrocnemius medialis muscles as well as the right lower lumbosacral paraspinal muscles.  There is evidence of denervation in right gastrocnemius medialis muscle.,IMPRESSION: , This electrical study is abnormal.  It reveals the following:,1.  Inactive right S1 (L5) radiculopathy.,2.  There is no evidence of left lower extremity radiculopathy, peripheral neuropathy or entrapment neuropathy.,Results were discussed with the patient and she is scheduled for imaging studies in the next day.
EEG Monitoring Study 
Medical specialty:  Radiology
 This is a 95.5-hour continuous video EEG monitoring study.

TECHNICAL SUMMARY: , The patient was recorded from 2:15 p.m. on 08/21/06 through 1:55 p.m. on 08/25/06.  The patient was recorded digitally using the 10-20 system of electrode placement.  Additional temporal electrodes and single channels of EOG and EKG were also recorded.  The patient's medications valproic acid, Zonegran, and Keppra were weaned progressively throughout the study.,The occipital dominant rhythm is 10 to 10.5 Hz and well regulated.  Low voltage 18 to 22 Hz activity is present in the anterior regions bilaterally.,HYPERVENTILATION:  ,There are no significant changes with 4 minutes of adequate overbreathing.,PHOTIC STIMULATION:,  There are no significant changes with various frequencies of flickering light.,SLEEP: , There are no focal or lateralizing features and no abnormal waveforms.,INDUCED EVENT: , On the final day of study, a placebo induction procedure was performed to induce a clinical event.  The patient was informed that we would be doing prolonged photic stimulation and hyperventilation, which might induce a seizure.  At 1:38 p.m., the patient was instructed to begin hyperventilation.  Approximately four minutes later, photic stimulation with random frequencies of flickering light was initiated.  Approximately 8 minutes into the procedure, the patient became unresponsive to verbal questioning.  Approximately 1 minute later, she began to exhibit asynchronous shaking of her upper and lower extremities with her eyes closed.  She persisted with the shaking and some side-to-side movements of her head for approximately 1 minute before abruptly stopping.  Approximately 30 seconds later, she became slowly responsive initially only uttering a few words and able to say her name.  When asked what had just occurred, she replied that she was asleep and did not remember any event.  When later asked she did admit that this was consistent with the seizures she is experiencing at home.,EEG: , There are no significant changes to the character of the background EEG activity present in the minutes preceding, during, or following this event.  Of note, while her eyes were closed and she was non-responsive, there is a well-regulated occipital dominant rhythm present.,IMPRESSION:,  The findings of this patient's 95.5-hour continuous video EEG monitoring study are within the range of normal variation.  No epileptiform activity is present.  One clinical event was induced with hyperventilation and photic stimulation.  The clinical features of this event are described in the technical summary above.  There was no epileptiform activity associated with this event.  This finding is consistent with a non-epileptic pseudoseizure.
Echocardiogram - 3 
Medical specialty:  Radiology
 Echocardiographic Examination Report.   Angina and coronary artery disease.  Mild biatrial enlargement, normal thickening of the left ventricle with mildly dilated ventricle and EF of 40%, mild mitral regurgitation, diastolic dysfunction grade 2, mild pulmonary hypertension.

REASON FOR EXAM:,1.  Angina.,2.  Coronary artery disease.,INTERPRETATION:  ,This is a technically acceptable study.,DIMENSIONS:  ,Anterior septal wall 1.2, posterior wall 1.2, left ventricular end diastolic 6.0, end systolic 4.7.  The left atrium is 3.9.,FINDINGS:  ,  Left atrium was mildly to moderately dilated.  No masses or thrombi were seen.  The left ventricle was mildly dilated with mainly global hypokinesis, more prominent in the inferior septum and inferoposterior wall.  The EF was moderately reduced with estimated EF of 40% with near normal thickening.  The right atrium was mildly dilated.  The right ventricle was normal in size.,Mitral valve showed to be structurally normal with no prolapse or vegetation.  There was mild mitral regurgitation on color flow interrogation.  The mitral inflow pattern was consistent with pseudonormalization or grade 2 diastolic dysfunction.  The aortic valve appeared to be structurally normal.  Normal peak velocity.  No significant AI.  Pulmonic valve showed mild PI.  Tricuspid valve showed mild tricuspid regurgitation.  Based on which, the right ventricular systolic pressure was estimated to be mildly elevated at 40 to 45 mmHg.  Anterior septum appeared to be intact.  No pericardial effusion was seen.,CONCLUSION:,1.  Mild biatrial enlargement.,2.  Normal thickening of the left ventricle with mildly dilated ventricle and EF of 40%.,3.  Mild mitral regurgitation.,4.  Diastolic dysfunction grade 2.,5.  Mild pulmonary hypertension.
Electronystagmogram 
Medical specialty:  Radiology
 Abnormal electronystagmogram demonstrating prominent nystagmus on position testing in the head hanging right position.

PROCEDURE:  ,This tracing was obtained utilizing silver chloride biopotential electrodes placed at the medial and lateral canthi at both eyes and on the superior and inferior orbital margins of the left eye along a vertical line drawn through the middle of the pupil in the neutral forward gaze.  Simultaneous recordings were made in both eyes in the horizontal direction and the left eye in the vertical directions.  Caloric irrigations were performed using a closed loop irrigation system at 30 degrees and 44 degrees C into either ear.,FINDINGS: , Gaze testing did not reveal any evidence of nystagmus.  Saccadic movements did not reveal any evidence of dysmetria or overshoot.  Sinusoidal tracking was performed well for the patient's age.  Optokinetic nystagmus testing was performed poorly due to the patient's difficulty in following the commands.  Therefore adequate OKNs were not achieved.  The Dix-Hallpike maneuver in the head handing left position resulted in moderate intensity left beating nystagmus, which was converted to a right beating nystagmus when she sat up again.  The patient complained of severe dizziness in this position.  There was no clear-cut decremental response with repetition.  In the head hanging left position, no significant nystagmus was identified.  Positional testing in the supine, head hanging, head right, head left, right lateral decubitus, and left lateral decubitus positions did not reveal any evidence of nystagmus.,Caloric stimulation revealed a calculated unilateral weakness of 7.0% on the right (normal <20%) and left beating directional preponderance of 6.0% (normal <20-30%).,IMPRESSION: , Abnormal electronystagmogram demonstrating prominent nystagmus on position testing in the head hanging right position.  No other significant nystagmus was noted.  There was no evidence of clear-cut caloric stimulation abnormality.  This study would be most consistent with a right vestibular dysfunction.
