EMG/Nerve Conduction Study 
Medical specialty:  Radiology
 History of numbness in both big toes and up the lateral aspect of both calves.  She dose complain of longstanding low back pain, but no pain that radiates from her back into her legs.  She has had no associated weakness.

HISTORY:,  The patient is a 52-year-old female with a past medical history of diet-controlled diabetes, diffuse arthritis, plantar fasciitis, and muscle cramps who presents with a few-month history of numbness in both big toes and up the lateral aspect of both calves.  Symptoms worsened considerable about a month ago.  This normally occurs after being on her feet for any length of time.  She was started on amitriptyline and this has significantly improved her symptoms.  She is almost asymptomatic at present.  She dose complain of longstanding low back pain, but no pain that radiates from her back into her legs.  She has had no associated weakness.,On brief examination, straight leg raising is normal.  The patient is obese.  There is mild decreased vibration and light touch in distal lower extremities.  Strength is full and symmetric.  Deep tendon reflexes at the knees are 2+ and symmetric and absent at the ankles.,NERVE CONDUCTION STUDIES: , Bilateral sural sensory responses are absent.  Bilateral superficial sensory responses are present, but mildly reduced.  The right radial sensory response is normal.  The right common peroneal and tibial motor responses are normal.  Bilateral H-reflexes are absent.,NEEDLE EMG:,  Needle EMG was performed on the right leg and lumbosacral paraspinal muscles and the left tibialis posterior using a concentric disposable needle.  It revealed increased insertional activity in the right tibialis posterior muscle with signs of mild chronic denervation in bilateral peroneus longus muscles and the right tibialis posterior muscle.  Lumbar paraspinals were attempted, but were too painful to get a good assessment.,IMPRESSION:  ,This electrical study is abnormal.  It reveals the following:,1.  A very mild, purely sensory length-dependent peripheral neuropathy.,2.  Mild bilateral L5 nerve root irritation.  There is no evidence of active radiculopathy.,Based on the patient's history and exam, her new symptoms are consistent with mild bilateral L5 radiculopathies.  Symptoms have almost completely resolved over the last month since starting Elavil.  I would recommend MRI of the lumbosacral spine if symptoms return.  With respect to the mild neuropathy, this is probably related to her mild glucose intolerance/early diabetes.  However, I would recommend a workup for other causes to include the following:  Fasting blood sugar, HbA1c, ESR, RPR, TSH, B12, serum protein electrophoresis and Lyme titer.

DIAGNOSIS:,  Possible cerebrovascular accident.,DESCRIPTION: , The EEG was obtained using 21 electrodes placed in scalp-to-scalp and scalp-to-vertex montages.  The background activity appears to consist of fairly organized somewhat pleomorphic low to occasional medium amplitude of 7-8 cycle per second activity and was seen mostly posteriorly bilaterally symmetrically.  A large amount of movement artifacts and electromyographic effects were noted intermixed throughout the recording session.

Dobutamine Stress Test - 1 
Medical specialty:  Radiology
 Dobutamine Stress Echocardiogram.  Chest discomfort, evaluation for coronary artery disease.  Maximal dobutamine stress echocardiogram test achieving more than 85% of age-predicted heart rate.  Negative EKG criteria for ischemia.

DOBUTAMINE STRESS ECHOCARDIOGRAM,REASON FOR EXAM: , Chest discomfort, evaluation for coronary artery disease.,PROCEDURE IN DETAIL: , The patient was brought to the cardiac center.  Cardiac images at rest were obtained in the parasternal long and short axis, apical four and apical two views followed by starting with a dobutamine drip in the usual fashion at 10 mcg/kg per minute for low dose, increased every 2 to 3 minutes by 10 mcg/kg per minute.  The patient maximized at 30 mcg/kg per minute.  Images were obtained at that level after adding 0.7 mg of atropine to reach maximal heart rate of 145.  Maximal images were obtained in the same windows of parasternal long and short axis, apical four and apical two windows.,Wall motion assessed at all levels as well as at recovery.,The patient got nauseated, had some mild shortness of breath.  No angina during the procedure and the maximal amount of dobutamine was 30 mcg/kg per minute.,The resting heart rate was 78 with the resting blood pressure 186/98.  Heart rate reduced by the vasodilator effects of dobutamine to 130/80.  Maximal heart rate achieved was 145, which is 85% of age-predicted heart rate.,The EKG at rest showed sinus rhythm with no ST-T wave depression suggestive of ischemia or injury.  Incomplete right bundle-branch block was seen.  The maximal stress test EKG showed sinus tachycardia.  There was subtle upsloping ST depression in III and aVF, which is a normal response to the tachycardia with dobutamine, but no significant depression suggestive of ischemia and no ST elevation seen.,No ventricular tachycardia or ventricular ectopy seen during the test.  The heart rate recovered in a normal fashion after using metoprolol 5 mg.,The heart images were somewhat suboptimal to evaluate because of obesity and some problems with the short axis windows mainly at peak exercise.,The EF at rest appeared to be normal at 55 to 60 with normal wall motion including anterior, anteroseptal, inferior, lateral, and septal walls at low dose.  All walls mentioned were augmented in a normal fashion.  At maximum dose, all walls were augmented on all views except for the short axis was foreshortened, was uncertain about the anterolateral wall at peak exercise; however, of the other views, the lateral wall was showing normal thickening and normal augmentation.  EF improved to about 70%.,The wall motion score was unchanged.,IMPRESSION:,1.  Maximal dobutamine stress echocardiogram test achieving more than 85% of age-predicted heart rate.,2.  Negative EKG criteria for ischemia.,3.  Normal augmentation at low and maximum stress test with some uncertainty about the anterolateral wall in peak exercise only on the short axis view.  This is considered the negative dobutamine stress echocardiogram test, medical management.

CT-Guided Needle Placement Biopsy 
Medical specialty:  Radiology
 CT of abdomen with and without contrast.  CT-guided needle placement biopsy.

EXAM: , CT of abdomen with and without contrast.  CT-guided needle placement biopsy.,HISTORY: , Left renal mass.,TECHNIQUE: , Pre and postcontrast enhanced images were acquired through the kidneys.,FINDINGS: , Comparison made to the prior MRI.  There is re-demonstration of multiple bilateral cystic renal lesions.  Several of these demonstrate high attenuation in the precontrast phase of the exam suggesting that they are hemorrhagic cysts.  There was however one cyst seen in the lower pole of the left kidney, which demonstrated apparent enhancement from 30 to 70 Hounsfield units post contrast administration.  This measured approximately 1.4 x 1.3 cm to the exophytic half of the lower pole.  No other enhancing renal masses were seen.  The visualized liver, spleen, pancreas, and adrenal glands were unremarkable.  There are changes of cholecystectomy.  Mild prominence of the common bile duct is likely secondary to cholecystectomy.  There is no abdominal lymphadenopathy, masses, fluid collection, or ascites.,Lung bases are clear.  No acute bony pathology was noted.,IMPRESSION: , Solitary apparently enhancing left renal mass in the lower pole as described.  Renal cell carcinoma cannot be excluded.,CT-GUIDED NEEDLE BIOPSY, LEFT KIDNEY MASS: , Following discussion of risks, benefits, and alternatives, the patient wished to proceed with CT-guided biopsy of left renal lesion.  The patient was placed in the decubitus position.  The region overlying the left renal mass of note was marked.  Area was prepped and draped in usual sterile fashion.  Local anesthesia was achieved with approximately 8 mL of 1% lidocaine with bicarbonate.  The Versed and fentanyl were given to achieve conscious sedation.  Utilizing an 18 x 15 gauge coaxial system, 3 core biopsies were obtained through the mass in question, and sent to pathology for analysis.  Following procedure, scans through the region demonstrate a small subcutaneous hematoma in the region of the superficial anesthesia.  No perinephric fluid/hematoma was identified.  The patient tolerated the procedure without immediate complications.,IMPRESSION: , Three core biopsies through the region of the left renal tumor as described.
