Abstract

Meningoencephalocoele (ME) of the temporal bone is otherwise known as brain fungus. It is a rare and potentially life-threatening condition. It occurs in cases of chronic otitis media either as a complication or iatrogenically induced following mastoid surgeries. It requires prompt surgical intervention. High-resolution Computer tomography of Temporal bone and Magnetic resonance imaging of the brain are needed to detect these cases. Surgery can be otological, neurosurgical, or combined. We discuss a case of Iatrogenic Temporal meningoencephalocele and its management along with a review of the literature.

Keywords: CSF otorrhea; Chronic otitis media; Mastoid surgery; Meningoencephalocoele.
