Back pain caused by a pseudo-tumorous vertebral collapse: atypical presentation of primary vertebral hydatidosis.
Hydatidosis, also known as echinococcosis, is a rare but serious parasitic disease in endemic areas. Primary spinal location is extremely rare. This case report describes a rare instance of hydatid cyst that caused severe and progressive low-back pain and neurologic dysfunction. Spine MRI showed a unique vertebral collapse of Th12 body with multicystic lesions filling the spinal canal. In addition, hydatidosis serodiagnostic test was positive at 1/725. Treatment depended on the actual surgical removal of the cysts. Surgery consisted in excision and extirpation of the cysts, associated with decompressive laminectomy. The diagnosis was confirmed on the basis of histological results. No coincidental hydatid visceral involvement was found. Antihelminthic drugs (Albendazole) were promptly given before surgery for a long period. The outcome was satisfactorily marked by total regression of the motor deficit and sphincter disorders.
