Background: Among the rare intraventricular cavernomas, purely intra-aqueductal cavernomas are exceptionally rare.
Case description: A 62-year-old patient presented with progressive headache, memory loss, gait instability, and urinary incontinence. Magnetic resonance imaging showed the presence of a mass lesion located in the lumen of the cerebral aqueduct, associated with triventricular hydrocephalus.
Conclusions: We discuss the rationale that led us to treat hydrocephalus with neuroendoscopy, which offered the possibility to directly inspect the intra-aqueductal lesion, make the diagnosis of cavernoma, and treat symptoms resulting from hydrocephalus without increasing the risk of bleeding.
