Primary lumbosacral intradural hydatid cyst in a child.

Primary spinal hydatid cyst is very rare lesion affecting less than 1% of the total cases of the hydatid disease. In this study, we report a case of spinal hydatid in a 5-year old boy presented with a history of backache, leg pain, difficulty in walking, and bowel and bladder incontinence for 4 months. An intradural nonenhancing cystic lesion was detected using magnetic resonance imaging from L4 to sacral region, and histopathological findings were suggestive of hydatid cyst.
