RADIOGRAPHIC AND COMPUTED TOMOGRAPHIC FINDINGS IN HYDATID-DISEASE OF BONE

Twenty-six patients with hydatid disease of bone were evaluated by means of radiography and conventional tomography. Fourteen patients underwent high resolution computed tomography (CT). In two patients with vertebral disease, magnetic resonance imaging (MRI) examination was also performed. Seventeen patients underwent surgery with histological examination in all. Based on the surgical data and gross examination of the specimen, the radiographic and CT findings have been reviewed to identify the most characteristic radiographic features and to assess the role of CT. Radiographic findings of hydatidosis are rarely typical in bone, and only in a few patients can CT contribute to the diagnosis. On the other hand, the local extension of the lesion both in bone and in soft tissues, which is essential in planning surgery, is always demonstrated well by CT. © 1990 International Skeletal Society.
