Discussant: Dr. James Ampil
Case presented by: Dr. Manav Heer


CC

leg pain, swelling, and near-syncope

HPI

67 yo Caucasian male was hospitalized for 4 weeks in the Middle East (Dubai) after presenting there with a hemorrhagic CVA on 2/15/03.
His stroke was complicated by aspiration pneumonia treated by IV Abx. MRI and MRA of head in Dubai showed no obvious source for bleed. He was treated with phenobarbital and gabapentin for seizure prophylaxis.

He returned to United States and on 4/3/03, he presented with chest pain and dyspnea. CT angiogram revealed bilateral pulmonary emboli. IVC filter was placed without anticoagulation given his recent CVA.

He was discharged 4/6/03, but returned 4/13/03 with leg pain and swelling. He also complained of lower abdominal tenderness. Doppler ultrasound revealed thrombosis of the right popliteal, right posterior tibialis, and left peroneal veins below the knee.

He was then discharged again and readmitted 2 days later with worsening leg pain, swelling, and near-syncope with balance problems.

HOSPITAL COURSE

Patient was started on IV Heparin, then Lovenox, and finally Fragmin subcutaneously despite the finding that he had a recent hemorrhagic CVA given his risks of further organ compromise (renal, GI, etc) from his massive DVT.

He did well and had no neurological events. PET was done which revealed no evidence for intracerebral metastases as cause for CVA; there was no focal accumulations of tracer in either kidney as well.

Patient was discharged home after 2U PRBCs for mild anemia. He was then readmitted and underwent partial left nephrectomy where a diagnosis was made. In addition, he was referred to another institution for a second opinion regarding his stroke.

An additional diagnosis was made…
