BACKGROUND: Sarcoidosis involves the nervous system about 5% of the time and usually manifests as a granulomatous inflammation of the basal meninges and hypothalamus. Cases which are strictly isolated to the central nervous system occur infrequently; rarely, they may present as an intracranial mass.
METHODS: We present the case of a solitary sarcoid granuloma at the cerebellopontine angle in a 42-year-old female who presented with headache, facial numbness, and hearing loss.
RESULTS: A suboccipital craniectomy was performed and the lesion was noted to be grossly adherent to the lower cranial nerves and skull base. The lesion was misdiagnosed as a meningioma with preoperative magnetic resonance imaging and intraoperative histology, and perhaps additional morbidity resulted.
CONCLUSION: We present this case in order to demonstrate the importance of differentiating these dural-based lesions and propose that cases of neurosarcoidosis presenting as a solitary granuloma be treated with surgical debulking and immunosuppression.
