Benign Pathology, Catastrophic Location
Colloid cysts are a rare developmental malformation that most commonly occur in the third ventricle at the level of the foramen of Monro. Although histologically benign and typically asymptomatic, colloid cysts can cause increased intracranial pressure and present with headache, papilledema, neurocognitive changes and occasionally gait abnormalities. Rarely, sudden death can occur from acute obstruction of the ventricular system. Most often colloid cysts are hyperintense on T1 and hypointense on T2-weighted MRI images. Treatment options include open microsurgical resection and more recently endoscopic resection
