Axial brain CT image shows a hypodense mass in the suprasellar region, extended to basal cisternae and frontal region, and surrounded the vascular structures, chiasm, and stalk.

On brain CT images a hypodense mass measuring approximately 5.3 x 4 cm in size was observed in the suprasellar region, extended to basal cisternae and frontal region, and surrounded the vascular structures and chiasm and stalk (Fig. 1).
(a) Axial T1 weighted brain MRI shows a hypo-intense mass in the suprasellar region (red arrow), extended to basal cisternae and frontal region (blue arrow) and surrounded the vascular structures, chiasm, and stalk. (b) Axial T2 weighted brain MRI shows a hyper-intense mass in the suprasellar region (red arrow), extended to basal cisternae and frontal region and surrounded the vascular structures, chiasm, and stalk. (c) Axial T1 weighted fat-suppressed, post-contrast brain MRI shows a hypo-intense mass in the suprasellar region, extended to basal cisternae and frontal region and surrounded the vascular structures, chiasm, and stalk. (d) Coronal T1-weighted fat-suppressed, post-contrast brain MRI shows a hypo-intense mass in the suprasellar region, extended to basal cisternae and displaced the vascular structures, chiasm and stalk.

In contrast-enhanced brain MRI, the same findings were noted (Fig. 2a, b). The lesion was extended to the frontal region as seen on CT, and some fat compatible signals were detected in this region (Fig. 2c and d).
(a) Axial DWI-MRI shows restricted diffusion in the suprasellar region. (b) Apparent diffusion coefficient maps show actual diffusion in the suprasellar region.

There was no post-contrast enhancement in the lesion but in diffusion-weighted MRI images, the restricted diffusion was observed within the lesion (Fig. 3a and b).
(a) Postoperative axial CT image shows post-operative changes and pneumocephalus in suprasellar region with no mass lesion. (b) Postoperative axial T1 weighted brain MRI image shows post-operative changes and pneumocephalus in the suprasellar region with no mass residual. (c) Postoperative axial Diffusion-weighted brain MRI image shows no restricted diffusion in the suprasellar region.

The postoperative brain CT and MRI performed at this time showed resection of the suprasellar lesion and postoperative changes. (Fig. 4a, b, and c).
