ABSTRACT
Pseudoaneurysm complicating osteochondroma is extremely rare. We describe a pseudoaneurysm in the popliteal fossa of a 21-year-old man, occurring 5 years after apparently incomplete resection of an osteochondroma at that site. We found magnetic resonance imaging and magnetic resonance angiography to be of great diagnostic value. Resection of the pseudoaneurysm and anastomosis of the popliteal artery were successful, with no recurrence detected for almost 7 years since the operation.

A 36-year-old man was admitted because of sopor and dark urine after intravenous amphetamine injection. He subsequently developed myoglobinuria and acute renal failure. Serum myoglobin value was remarkably elevated to 83,000 ng/ml, and urine myoglobin was 400,000 ng/ml. Renal biopsy revealed tubular degeneration and tubular obstruction with myoglobin casts by immunofluorescence examination. Amphetamine-induced rhabdomyolysis was suspected to cause myoglobinuric acute renal failure.
