Surgical Management of Spinal Cysticercosis: 2-Dimensional Operative Video

Abstract

Neurocysticercosis is a notorious—albeit relatively rare—parasitic infection of the nervous system caused by ingestion of embryonated eggs or gravid proglottids of the pork tapeworm Taenia solium. 1 Most cases appear intracranially and can present with seizures and/or headache; far fewer affect the spinal canal alone. 1-6 We describe a case of a 66-year-old Hispanic man with isolated spinal cysticercosis presenting to the emergency department initially with axial back pain. After lumbar x-rays and a computed tomography scan failed to find any pathology, he was discharged home without neurosurgical consultation. A week later he would re-present to the same emergency department with worsening back pain and new neurologic deficits, prompting an MRI revealing pathology within the lumbar spinal canal. After consultation, the neurosurgical team discussed management strategies and eventually opted for surgical exploration of the patient's lumbar spine. This exploration eventually culminated in an intradural exploration, revealing an impressive string of interconnected larval cysts of the T. solium tapeworm within the cauda equina. The patient's neurologic condition improved immediately after surgery, and final pathologic examination supported a diagnosis of spinal cysticercosis, prompting the appropriate workup and medical treatment. He would ultimately make a full recovery and continues to follow-up with infectious disease at our institution. The patient consented to the surgical intervention described herein after a discussion of its risks, benefits, and alternatives. Institutional review board and ethics committee approval was not sought because the intervention did not constitute experimental surgery, but rather represented standard of care given the patient's condition on presentation.
