In reports originating from a period prior to computed tomography (CT) and MRI, the possibility of the existence of a single extradural hydatid cyst or of soft tissue involvement without bony origin was viewed with scepticism [13,19].

IntroductionHydatid disease is more common in young people who have had contact with dogs, wolves or cats [9,12]. In a large percentage of cases, echinococcus granulosus usually involves the liver and lungs.Hydatid disease of the bone is found in 1% of all cases, with the spine being involved in 45% of bone infestations. Disease usually spreads to the spine by direct extension from pulmonary, abdominal or pelvic infestation, and most commonly affects the dorsal region [2,9,11,12,20]. Primary spinal extradural hydatid cyst is extremely rare.A rare case of primary lumbar extradural hydatid cyst, which causes cauda equina compression, is reported and clinical presentation, diagnosis and surgical treatment are discussed. Case reportAn 8-year-old boy from Eastern Anatolia, who had not suffered from any other disease till then, presented with back pain, progressive weakness, numbness in both legs and difficulty in walking; all symptoms having appeared 7 months earlier.Physical examination showed no abnormality. Neurological examination revealed perianal hypoesthesia and paraparesis prominent on the right and distal muscle groups. There was loss of patella and Achilles reflexes, as well as urinary and anal incontinence.Abdominal ultrasonography scans and magnetic resonance (MR) images of the cranium and cervical region were normal. MRI of the lumbar region showed an intracanalicular cystic lesion with a regular contour and extradural location, with dimensions of 4.9 cm craniocaudally and 2.5 cm axially. There was cerebrospinal fluid-(CSF-) like signal intensity on T1-and T2-weighted images. The lesion had excessively compressed the dural sac and caudal roots and had expanded to the L3 and L4 neural foramina without any bone involvement (Fig. 1). Initially, the lesion was considered to be a hydatid cyst, but serological tests (specific ELISA/Western blot) proved negative.The case was explored with L2, L3, L4 laminectomy. The lesion was removed totally, with a fibrous pseudocapsule that tightly adhered to the dural sac and bone, and the cavity was irrigated with hypertonic saline. Histopathological examination revealed a hydatid cyst.Albendazole treatment was applied in the early postoperative stage. Paraparesis was improved almost completely in later controls extending over 3 years, and postoperative MRI scans showed that the hydatid cyst had been totally removed (Fig. 2). Anal incontinence was improved, while urinary incontinence persisted, but in a decreasing manner.Abstract Spinal hydatid cyst is a rare but serious condition. An 8-yearold boy presented with back pain, progressive weakness and numbness in both legs. Magnetic resonance imaging (MRI) of the lumbar region showed a cystic lesion with regular contour located in extradural space. There was cerebrospinal fluid-(CSF-) like signal intensity on T1-and T2-weighted images. The lesion had excessively compressed the dural sac and caudal roots, and expanded to the L3 and L4 neural foramina. The case was explored with L2, L3, L4 laminectomy and the hydatid cyst was r...

Spinal hydatid cyst is a serious but fortunately uncommon manifestation of the parasite Echinococcus, involving less than 1% patients with hydatid disease. Intradural hydatid cysts are extremely rare compared to other types of spinal hydatid cysts. We report a rare case of intradural, extramedullary spinal hydatid cyst in a 9-yearold male boy, who presented with weakness of both lower limbs for the last 4 months that was confirmed histopathologically; a better understanding of this rare but clinically challenging disease is intended by reporting this case.
