Apoplexy in a Metastatic Pituitary Mass: A Rare Occurrence

Abstract

Pituitary apoplexy resulting from metastatic disease is an uncommon and rapidlyprogressive clinical presentation. This report details the case of a gentleman whopresented with episodic severe headaches, a unilateral third nerve palsy, andprogressive visual field loss. Initial blood tests indicated an abnormal pituitaryhormone profile, while MRI imaging revealed a sellar mass exhibiting featuresconsistent with apoplexy. Due to the acute threat to his vision, an urgent reviewwas conducted at a pituitary multidisciplinary meeting, leading to endoscopictranssphenoidal decompression. The patient had a prior history of colorectal cancer,treated 18 months earlier and previously regarded as in remission. Subsequenthistological analysis confirmed that the pituitary lesion was a metastasis fromcolorectal cancer. This case illustrates the diagnostic and therapeutic complexitiesinherent in managing this rare presentation
