Visual improvement during octreotide therapy in a case of episellar meningioma.

Meningiomas of the tuberculum sellae can induce compression of the optic tract. We report the case of a 54-year-old female patient affected by a suspected pituitary macroadenoma with severe visual field defects, who experienced a significant clinical and visual improvement during short-term octreotide therapy, contrasting with the lack of neuroradiological evidence for tumor shrinkage. The patient subsequently underwent transcranial surgery with a final diagnosis of meningioma. The putative mechanisms of visual improvement during octreotide therapy are discussed.
