This MRI study of brain shows:
A well demarcated ovoid soft tissue signal intensity mass confined to sella seems to be the enlarged pituitary gland itself as pituitary gland is not seen separately in hypophyseal fossa, mild to moderate enhancement on post contrast T1. Both the ICAs are encased. Abnormal marrow signals involving clivus with erosions of floor of hypophyseal fossa. Sphenoid sinus show marked mucosal thickening and soft tissue. No significant mass effect on supra sellar anatomy.
Imagingwise diagnosis : Invasive / Aggressive Macroadenoma.
Tran sphenoid scopy and biopsy attempted, histopathology reports Macroadenoma.
