INTRODUCTION: Nervous system involvement occurs in 5 to 15% of the patients with
sarcoidosis. Neurosarcoidosis remains very difficult to diagnose because clinical
presentation and imaging characteristics lack specificity.
OBSERVATION: We report a 26-year-old man who gradually developed headaches,
memory disturbance and epilepsy. CT-scan and MRI showed a temporal-parietal
cystic mass, secondary to a rare and focal form of hydrocephalus, called « trapped
temporal horn » revealing neurosarcoidosis.
CONCLUSION: 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.
