Intradural Neurocysticercosis of Lumbar Spine: A Case Report

Study Design Case report. Objective Cysticercosis (parasitic infection caused by Taenia solium) is the most common parasitic infection of the nervous system. However, spinal neurocysticercosis is rare. It can present as an extraspinal or intraspinal lesion, with intramedullary being the rarest location. The symptoms can vary from vague backache and radiculopathy to cauda equine syndrome. Methods We report a 32-year-old man who presented with neurocysticercosis in the lumbar spine and cauda equine syndrome. He had low backache for 1 month, hesitancy in micturition, and decreased perianal sensation for the previous 2 days. Magnetic resonance imaging revealed an intradural extramedullary lesion extending from L2-S1 that was hyperintense in T2- and hypointense in T1-weighted images. Results Because the patient presented with cauda equine syndrome, urgent decompressive laminectomy was done from L2-S1, and the thin-walled cysts with clear fluid were removed. Histopathologic examination confirmed neurocysticercosis. The perianal sensation and the bladder control recovered completely. Conclusion Neurocysticercosis should be considered in the differential diagnosis in patients presenting with a similar picture, and urgent surgical decompression should be attempted to prevent further worsening of the neurologic symptoms.
