Neurosarcoidosis of the trigeminal nerve: clinical accompaniments, radiographic findings, and association with neuralgia.

Background: Cranial neuropathy is a principal disease manifestation of neurosarcoidosis, but many forms remain poorly described, including trigeminal nerve disease despite its frequency in reported cohorts (5-12%). Herein, we characterize the clinical course of patients with neurosarcoidosis involving the trigeminal nerve.

Methods: A single-center retrospective cohort analysis of patients with biopsy-proven sarcoidosis involving the trigeminal nerve was conducted between 1/1/2000-3/7/2023.
