Abstract:
The massa intermedia (MI) or interthalamic adhesion (ITA) is a band of tissue connecting the medial surfaces of the thalami and is present in the majority of healthy individuals. Its enlargement as well as its absence have been associated with some pathological states.We describe the first case report of a 3-year-old child presenting with obstructive hydrocephalus in the context of an enlarged massa intermedia. The patient's symptoms abated following an endoscopic third ventriculostomy.
