Multiple cranial nerve dysfunction caused by neurosarcoidosis.

Neurosarcoidosis is a rare identity and occurs in only 5% to 15% of patients with sarcoidosis. It can manifest in many different ways, and therefore, diagnosis may be complicated. We report a case presented in a very unusual manner with involvement of 3 cranial nerves; anosmia (NI), facial palsy (NVII), and hearing loss (NVIII). When cranial nerve dysfunction occurs, it is very important to take neurosarcoidosis into consideration.
