Epidermoid (frontal) and pituitary macroadenoma
Presenting with bitemporal hemianopia.
At the medial aspect of the right frontal lobe a lobulated lesion demonstrates predominantly low T1 and very high T2 signal with little if any enhancement. Diffusion weighted imaging reveals prominent restricted diffusion.
MRI of the pituitary: same day
Appearances of the frontal lobe mass are most consistent with an epidermoid cyst.
Additionally as pituitary mass is noted, consistent with a coincidental pituitary macroadenoma.
