Radiographic appearance of a sellar and suprasellar meningioma in the current patient (a) Axial T1 MRI with gadolinium showing large homogeneously enhancing suprasellar mass. (b) Sagittal T1 MRI with gadolinium showing sellar/suprasellar mass with enhancing dural tail along planum sphenoidale. (c) Coronal T1 MRI with gadolinium showing superior displacement of optic chiasm

Imaging characteristics were most consistent with a tuberculum sella meningioma [Figure 1].
MRI head post resection of sellar/suprasellar meningioma. (a) Axial T1-weighted MRI with gadolinium showing extensive leptomeningeal enhancement around the base of the brain and postsurgical packing with no evidence of residual tumor, and (b) coronal T1-weighted MRI with gadolinium showing enhancement extending along the optic nerves and infundibulum. (c) T2-weighted trace, acquired from diffusion-weighted MRI, highlighting infarcts within the caudate head bilaterally, more extensively present on the right

MRI of the head revealed extensive leptomeningeal enhancement, surrounding the optic nerves and chiasm, into the Sylvian fissures and encasing the infundibulum [Figure 2a]. MRI revealed bilateral caudate head infarcts, more extensive on the right with involvement of the adjacent capsular white matter and right anterior inferior lentiform nucleus infarct [Figure 2b]. MR angiography revealed constricted left and right A1 segments, Sylvian M1 segments, and the basilar artery [Figure 3].
