An extensive vertebral hydatidosis revealed by a lumbosciatica.

The vertebral hydatidosis is uncommon. It causes problems in diagnosis and in management. A case of an extensive vertebral hydatidosis with few symptoms is reported. A 21-year-old man has consulted for recurrent lumbosciatica that has been evolving for 1 year. Clinical exam was normal. Plain radiographic films disclosed a lytic lesion throughout the bodies of L4 and L5 and calcifications thrown on the liver area. The computed tomography (CT) and the magnetic resonance (MR) images revealed multicystic bony lesions involving the lumbar spine with extension into the spinal canal. Abdominal ultrasound showed also cyst lesions in the right kidney and in the liver. The diagnosis of vertebral and abdominal (liver and kidney) hydatidosis was retained. Four sets of 4-week albendazole cures were given with a 2-week interval in between. Our case of extended vertebral hydatidosis with few symptoms confirms the clinical latency and diagnosis difficulties usually encountered in this disease. This often leads to a late diagnosis of the stage of spinal cord compression. Radiological diagnosis and determination of extension of the hydatid cyst are usually provided by CT and MRI. Vertebral hydatidosis should be evoked in lumbosciatica especially in endemic regions.
