(A) Pre-operative T1-weighted images showing an isointense lesion at the suprasellar cistern (craniopharyngioma - thick arrow) and an isointense to marginally hyperintense lesion related to the right carotid artery (pituitary adenoma - thin arrow), with mixed intensity after contrast enhancement, (B) post-operative T1-weighted images, before and after gadolinium administration, showing the adenoma (thin arrow) and no residual craniopharyngioma tissue, (C) pre- and post-contrast-enhanced T1-weighted images one year after the initiation of long-acting somatostatin analogue treatment showing no craniopharyngioma regrowth and stable appearances of the adenoma (thin arrow).

Subsequent head magnetic resonance imaging (MRI) disclosed a suprasellar heterogeneous, mainly cystic, 1.9 x 2 x 1.9 cm mass compressing and displacing the optic chiasm and expanding to the third ventricle without causing hydrocephalus; these findings were considered to be consistent with a craniopharyngioma (Fig. 1A), and he was referred for surgery.
