Intracerebral granular cell tumors (GCTs) are a rare finding. We report here on a case of cerebral GCT in a 47-year-old man who suffered with severe headache. The tumor appeared as a relatively well-defined, enhancing mass at the periventricular white matter of the left occipital lobe of the brain.
