Huge craniopharyngioma: diffusion MRI and contrast-enhanced FLAIR imaging

Comput Med Imaging Graph. May-Jun 2002;26(3):199-203. doi: 10.1016/s0895-6111(01)00043-x.

Abstract

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 x 10(-3)mm(2)/s, compared to that of normal cerebellar parenchyma 0.85 x 10(-3)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 fluid.
