A 64-year-old man with a 4-year history of disseminated adenocarcinoma of the prostate was admitted to the Department of Neurosurgery with an acute onset of diplopia and severe headaches. Neurological examination revealed an isolated right-sided palsy of the abducens nerve. Magnetic resonance imaging showed an intracranial contrast-enhancing mass located in the right-sided cavernous sinus extending into the sellar region without involvement of neighboring osseous structures (Figure 1). Radiologically, the lesion was regarded as either adenoma or meningioma and the patient underwent tumor resection via a minimally invasive binasal endoscopic transsphenoidal approach, which led to a rapid postoperative improvement of diplopia.
