Hydatid disease of bones and joints: 8 cases followed for 4-16 years

Abstract

Hydatid disease is a rare parasitic disease that seldom involves the skeleton. Treatment is difficult because of problems with the preoperative diagnosis, the invasive nature of the bony involvement and the variable anaphylactic reaction to the cyst fluid antigen. We present 8 cases with osseous hydatidosis who were treated over a period of 11 years. The spine was involved in 2 cases, the ilium in 2, the hip in 2, the tibia in 1 and the humerus in 1. We point out that diagnosis is difficult and the prognosis is often poor.
