Primary Hydatid Disease of the Ilium: A Case Report

Bone hydatid disease is endemic in several regions worldwide and lacks a typical clinical appearance and image characteristics; therefore, its diagnosis is very difficult. A 49-year-old rural woman was referred with purulent discharge from sinus tract in the left ilium. X-ray and CT scan showed multiple lytic lesions with cortical destruction. She was scheduled for sequestrectomy with impression of chronic osteomyelitis but destroyed hydatid cysts were detected intraoperatively. Iliac wing excision from the iliac crest to the sacroiliac joint and supraacetabulum area was performed. Pathologic findings were in favor of bone hydatidosis. Postoperatively, albendazole and antibiotics were prescribed.
