Human sparganosis is one of the fhost common tissue parasitoses caused by helminthes in Korea. Human sparganosis is found most frequently in subcutaneous or adipose tissue of the abdominal wall, thoracic wall and inguinal region, it is rarely found in the orbital cavity, abdominal cavity, brain, breast, or lower extremities. We experienced one ease of sparganosis which developed into the thigh and popliteal area in combination with avascular necrosis of the femoral head. The case is a 59 years old male. The patient had the history of eating raw meat as a tonic food 3 years ago. The presenting symptom was left hip joint pain. We confirmed the sparganosis in microscopic findings of worms and by immunologic serum studies. The avascular necrosis of the femoral head was detected with plain roentgenography and magnetic resonance imaging. Many spargana were removed from the lesions by surgical excision. Two of them were alive, and others had degenerated or calcified. The life cycle and route of infestation of sparganosis were discussed briefly and related literatures were reviewed.
