[Vertebral hydatidosis [Report of 22 cases]]

Hydatidosis affects the bone in 0.5 to 2% of cases, with 44% of these cases involving the spine. To describe the radiological characteristics of spinal hydrated. This retrospective study about 22 patients [14 men and 8 women] aged between 10 and 63 years old. The mean age was 29 years, they were explored by conventional explorations in 22 cases, myelography in 12 cases, computed tomography in 15 cases and magnetic resonance imaging in 3 cases. Imagning showed multicystic bony lesions. Thoracic involvement was present in 13 cases, lumbar involvement in 5 cases, cervical in 2 cases and sacral involvement in 2 cases. The process involved 2 adjacent vertebrae in 4 cases, 3 adjacent vertebrae in 5 cases, 4 adjacent vertebrae in 2 cases and the entite sacrum in 2 cases. Vertebral collapse was noted in 3 cases. The extension into the spinal canal was noted in 5 cases. Other sites of involvement were also noted, especially in liver and spleen. The presence of multicystic vertebral lesions with involvement adjacent soft tissues should raise the possibility of spinal hydatidosis in endemic countries

Primary spinal extradural hydatid cyst.

We report a rare case of spinal cord compression caused by primary multiple extradural hydatid cysts.
