Abstract
|
|
|
|
Diaphragma sellae meningioma is a rare entity and its clinical and radiologic findings of are similar to those of pituitary macroadenomas. It is important to differentiate the rare diaphragma sellae meningioma from the common non-functioning pituitary macroadenoma, especially with regards to the surgical approach. We report a rare case of diaphragma sellae meningioma mimicking non-functioning pituitary macroadenoma in a 65-year-old male patient who presented with bitemporal hemianopsia and panhypopituitarism. The patient underwent the tumor removal via the transsphnoidal and transcranial approaches in two times. Careful MRI evaluation is exceedingly valuable for differentiation between two disease entities. The main findings considered are contrast enhancement, visibility and displaced direction of the normal pituitary gland, the center of the lesion and sellar enlargement.
