title: Colloid cyst of the third ventricle presenting with features of Terson's syndrome.
abstract: This report describes a middle-aged man presenting to the ophthalmologist with history of seeing floaters before both eyes since 2-weeks duration. A history of intermittent headache and dizziness of recent onset was elicited on questioning. Ocular examination showed bilateral early papilloedema and mild vitreous hemorrhage. Brain computed tomography (CT) disclosed features suggestive of colloid cyst of the third ventricle in the region of foramen of Monro with moderate hydrocephalus. Emergency craniotomy and excision of the cyst was done, and the patient is doing well for the last 18 months after the surgical intervention. The mechanism of this presentation, importance of early investigations, and timely intervention are highlighted in order to avoid serious neurological sequelae. The literature was extensively reviewed for atypical presentations of intraventricular colloid cyst.
