Abstract
We report a 61-year-old woman with definite diagnosis of isolated neurosarcoidosis in the medulla oblongata involving the fourth ventricle. We could not recognize neurosarcoidosis as one of the differential diagnoses of the lesion before biopsy because the brainstem lesion location and periventricular lesion configuration were quite unusual.
