To the Editor: A colloid cyst, also called a neuroepithelial cyst, is a slow-growing, benign tumor that occurs in the anterior third ventricle.1 Colloid cysts of the third ventricle represent 0.5%−2% of all intracranial tumors.2,3 The cyst typically blocks the foramen of Monro, causing obstructive hydrocephalus involving only the lateral ventricles. The common presenting symptoms are headache, nausea, vomiting, memory loss, mental status changes, gait disorder, insomnia, and visual disturbances.4 We report a case who presented with organic manic disorder, which remitted after the surgery.
