(A) Pre-operative MRI scans with contrast show the pituitary tumor measured 3.6 cm x 2.35 cm x 2.83 cm causes erosion of the sellar floor and encasement of the left cavernous structure including the internal carotid artery. (B) Post-operative MRI scans with contrast show that the residual tumor is still located mainly in the left side of the sellar fossa and parasellar structures including the cavernous sinus and Meckel's cave.

Magnetic resonance imaging (MRI) revealed a sellar tumor with parasellar and suprasellar extension and optic chiasm compression (Figure 1A). This patient underwent transnasal transsphenoidal surgery, and the sellar tumor was partially removed (Figure 1B).
Series of brain MRI scans with contrast shows newly noted focal dilation of left cavernous ICA (diameter: 1.3 cm) and medial protrusion (0.75 cm) in the cavernous ICA. since 2020.06.

An annual follow-up image demonstrated no interval change in tumor size and no vascular abnormalities (Figures 2A-D).

A hematoma at the sellar turcica and an intraventricular hemorrhage were found on brain computer tomography (CT) (Figure 3A). A cerebral angiogram revealed a fusiform aneurysm measuring 1.55 x 1.45 cm arising from the cavernous segment of the left internal carotid artery, with contrast extravasation from the aneurysm to the sellar turcica, and another saccular aneurysm measuring 0.7 x 0.6 cm arising from the left posterior communicating artery (Figures 3B-D).
