Huge Invasive Pituitary Adenoma with Involvement of Middle and Posterior Fossa

Abstract

A case of huge invasive chromophobe pituitary adenoma is reported. The tumor extended to the right middle and posterior fossa, and recurred one year following resection and irradiation. The patient developed visual disorders, hyperprolactinemia, right trigeminal nerve involvement and left hemiparesis. Review of pertinent literature indicates that there is no better treatment than non-radical resection followed by irradiation for invasive adenomas at present.
