Mature teratoma arising from the sella--case report.

A 26-year-old, short statured, obese male presented with a mature teratoma located entirely within the dural confines of the sella manifesting as headaches and progressive loss of vision. He had panhypopituitarism. Magnetic resonance imaging showed a large sellar-suprasellar but entirely infradiaphragmatic tumor of varying consistency. The tumor was resected through a trans-sphenoidal route. The tumor had elevated the diaphragma sellae to a significant extent but did not pass through. Histological examination confirmed a mature teratoma.
