✦ Synopsis

Craniopharyngiomas are most commonly located extraaxially in the suprasellar area. They are benign but aggressive neoplasms. An adult patient is reported to have a huge craniopharyngioma with gross extensions to the surroundings. In diffusion MRI, it had high signal for b 1000 mm 2 =s (true diffusion) images, and at the same time, high ADC values ( 2.12 and 2:27 £ 10 23 mm 2 =s; compared to that of normal cerebellar parenchyma 0.85 £ 10 23 mm 2 /s). In FLAIR images, obtained after administration of intravenous contrast medium, an intense, diffuse enhancement pattern was seen involving the viable tumor portions as well as the intratumoral ¯uid.
