Suprasellar RCC appears hyperintense on T1WI (a, b) without contrast enhancement (d). On coronal T2WI (c), an arrow indicates an intracystic hypointense nodule, a typical sign of RCC, related to proteinaceous concretion. MR angiography (e) can be useful to rule out the possibility of an aneurysm, but the cyst will appear mildly hyperintense on MIP reconstruction
