Cavernous sinus tuberculoma mimicking a neoplasm: Case report, literature review, and diagnostic and treatment suggestions for tuberculomas in rare locations.

Background: Cavernous sinus tuberculomas are extremely rare, but the increasing incidence worldwide of central nervous system (CNS) tuberculosis, mostly due to human immunodeficiency virus and poor sanitary conditions, and the ability of tuberculomas to mimic a brain neoplasm makes cavernous sinus tuberculomas a suspicious pathologic finding in the differential diagnosis of a brain space-occupying lesion.

Case Description: We present an immunocompetent patient with no signs of systemic tuberculosis and an isolated right cavernous sinus space-occupying lesion. A skull base approach was performed and tumor resection achieved.
