Neurosarcoïdose de présentation atypique

The “entrapped temporal horn” is due to an obstacle on the cerebrospinal fluid pathway at the trigone of the lateral ventricle that seals off the temporal horn and the choroid plexus from the rest of the ventricular system. The obstacle is related to the granulomatous tissue of sarcoidosis. Therefore, the “trapped temporal horn” acts as a space occupying process, causing headaches, memory pain, hemiparesis, homonymous hemianopsia, and requires medico-surgical management.
