{{::suprasellar_lesion808252.jpg?500|}}

A hyperintense [[suprasellar lesion]] is identified in [[T2]] sequence and [[hypointense]] in [[T1]] sequence, which heightens in a heterogeneous way after [[contrast]] administration, with the presence of necrotic [[cyst]]ic areas inside. The approximate diameters of the lesion are 15 x 11 x 11 (craniocaudal, transverse and anteroposterior respectively). The tumor broadly encompasses the [[pituitary stalk]], with only the most distal portion of it being respected.

Likewise, the tumor exerts a mass effect on the [[optic chiasm]], which is cranially displaced and widened.
The findings described raise the differential diagnosis of suprasellar lesions such as [[craniopharyngioma]], [[neurocytoma]], [[metastases]], [[pituitary neuroendocrine tumor]] of ectopic location ...
