Primary Spinal Extradural Hydatid Disease

Abstract

A rare case of hydatid disease of the lumbar extradural area and of the paravertebral muscles is reported. The patient underwent surgery, resulting in complete recovery. The limitations of computed tomography and the benefits of magnetic resonance imaging in forming a diagnosis are discussed. Magnetic resonance has been found to be an invaluable tool, not only in detecting the soft tissue extent of the disease but also in delineating the viability of hydatid cysts.
