Disorder of pituitary gland, unspecified [E23.7], Reason for Study: ^Reason: please evaluate pituitary mass seen on CT History: above There is a relatively well circumscribed, globular large sellar mass with suprasellar extension displacing optic chiasm superiorly and posteriorly. The mass is measured about 26.7mm x 40.6mm x 22.2mm with relatively homogeneous enhancement. On post contrast enhancement coronal scan, the mass appears to be extended toward right side cavernous sinus as well as right side Meckel's cave.Posterior wall of the sphenoid sinus shows anterior convexity but the sphenoid sinus does not show any evidence of fluid collection indicating direct involvement.Underlying brain shows minimal brain atrophy with non specific small vessel ischemic disease which are age appropriate. The ventricles, sulci and cisterns are symmetric and unremarkable. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
Large sellar mass with suprasellar extension with homogeneous enhancement indicating macroadenoma of pituitary gland most likely. Differential diagnosis include metastasis, pituitary carcinoma, meningioma and craniopharyngioma. No evidence of acute ischemic or hemorrhagic lesion.
