title: Granular cell tumor in the pituitary stalk: a case report.
abstract: Granular cell tumors (GCTs) have been reported in various tissues, especially the skin and subcutaneous soft tissue of the head and neck. We report a 60-year-old man who presented with intermittent headache and dizziness for 3 months, but no other neurological symptoms. Magnetic resonance imaging (MRI) showed the presence of a mass in the pituitary stalk, and contrast-enhanced MRI showed nodular enhancement in this region. The lesion was completely excised microscopically via a frontotemporal (pterional) approach. On pathological examination, a final diagnosis of a typical GCT was made.
