BackgroundAlthough extraparenchymal neurocysticercosis (NCC) is well established, presentation in the suprasellar space is rare. When presenting in the suprasellar space, the imaging characteristics may mimic more common lesions including craniopharyngioma and Rathke cleft cyst depending on the life cycle of the parasite. Although antiparasitic medical therapy may be effective for viable NCC, it is not routinely employed for calcified NCC.Case DescriptionThis report presents a 39-year-old male patient who presented with profound visual decline secondary to a partially calcified suprasellar NCC. Suprasellar NCC was presumed based on specific radiologic findings, which are discussed. Medical therapy was not offered because of the proximity to the optic chiasm and the partial calcification of the lesion leading to the presumption that the mass was nonviable. The patient underwent successful endoscopic endonasal resection of the suprasellar NCC and experienced significant improvement in vision. Despite the calcification, pathological evaluation revealed that a portion remained viable.ConclusionsRegardless of the life cycle stage, endonasal resection offers a minimally invasive approach for suprasellar NCC; treatment can be tailored to the patient's presentation and stage of infection.Copyright © 2020 Elsevier Inc.
