Abstract (Spanish) || Full Text || PDF (Spanish) || PDF (English)



Introduction: The extraparenchymal neurocysticercosis and the racemose form are very predisposed to complications. Subarachnoid sellar cysts are rare, are associated with intracranial hypertension and disorders visual fields.

Clinical case: A 63-year-old male patient with racemose neurocysticercosis, hydrocephalus and cerebrospinal fluid fistula. He underwent transnasal endoscopy, removal of cysts from the sphenoid sinus, sellar, suprasellar, and prepontine regions, and fistula closure. He also presented erosion in the temporal bone and dural fistula, which were closed through microsurgery and endoscopy. The patient had a favorable initial evolution, with spastic quadriparesis, which improved with rehabilitation. Subsequently he presented episodes of ventriculoperitoneal shunt system dysfunction.

Conclusion: Neuroendoscopy is a diagnostic and therapeutic method of various forms of neurocysticercosis. Extraparenchymal neurocysticercosis is able to produce bone and dural erosion, so must be considered in the differential diagnosis of cerebrospinal fluid.
