We present three cases of rare intracranial midline tumor in the sellar region, often mimicking pituitary adenomas clinically. We describe their symptoms, radiological and pathomorphological features. The first case is a pituitary adenoma producing growth hormone with ganglion cell differentiation. In addition, a rare intracranial granular cell tumor of sellar region and germinoma of pituitary fossa are also presented. All tumors were resected and histologically analyzed. Their biological behaviour was favorable with a 10-year follow-up demonstrating no recurrent tumor mass.
