PURPOSE: To evaluate the CT findings of skeletal cystic echinococcosis.
MATERIAL AND METHODS: CT findings of 7 patients with pathologically confirmed skeletal cystic echinococcosis were evaluated.
RESULTS: There were 4 men and 3 women, aged 36-75 years. Hydatid cysts were located in the spine (n=2), a rib (n=3), the pelvis and a vertebra (n=1), the pelvis and the left femur (n=1). The size of the lesions varied from 1 cm to 15 cm. CT showed well defined, single or multiple cystic lesions with no contrast enhancement, no calcification, no daughter cysts, and no germinal membrane detachment. The cystic lesion had a honeycomb appearance in 2 cases; there was pathologic fracture in 2 cases, bone expansion in 5 cases, cortical thinning in 6 cases, cortical destruction in 6 cases, bone sclerosis in 1 case, and soft tissue extension in 6 cases.
CONCLUSION: Preoperative differential diagnosis of skeletal cystic lesions should include cystic echinococcosis, especially in endemic areas, since this diagnosis may easily be missed unless kept in mind.
