Transsphenoidal surgery of intrasellar germinomas. Report of two cases.

Two patients with diabetes insipidus, hypopituitarism, and an enlarged sella turcica underwent a transsphenoidal operation for the treatment of intrasellar germinomas. Successful transsphenoidal treatment of such neoplasms has not been reported previously. The cases indicate that the diagnostic possibility of intrasellar germinoma should be considered in young patients with combined diabetes insipidus and hypopituitarism, even when the sella is markedly expanded.
