Pre-treatment magnetic resonance imaging (MRI) and computed tomography (CT) angiography of the aneurysm. MRI T1-weighted sequences mid-sagittal section with contrast (a) shows a large intrasellar lesion (white arrow) with an unusual pattern of enhancement, which is different from a pituitary adenoma and necessary for further investigation for an aneurysm. CT angiography 3D reconstruction (b) demonstrates a large right supraclinoid ICA aneurysm (black arrow) extending into the sellar region.

Magnetic resonance imaging (MRI) revealed a sellar mass that was considered to be a large intracranial aneurysm (Fig. 1a). Computed tomography angiography (CTA) as well as digital subtraction angiography (DSA) revealed a right ICA supraclinoid segment aneurysm (Figs. 1b and 2a).
Digital subtraction angiography (DSA) of the aneurysm before and after coiling. DSA lateral projection of the aneurysm (left black arrow) pre-treatment (a) and after coiling (right black arrow) (b) shows the right ophthalmic segment internal carotid artery aneurysm.

Computed tomography angiography (CTA) as well as digital subtraction angiography (DSA) revealed a right ICA supraclinoid segment aneurysm (Figs. 1b and 2a). At our hospital, we performed placement of coils into the aneurysm for treatment (Fig. 2b) 7 days after admission followed by a continued hydrocortisone, levothyroxine, and testosterone replacement therapy.
