Diagnostic Significance of Intracystic Nodules on MRI in Rathke’s Cleft Cyst
Figure 2
Case 10: nonenhanced MRI shows bull’s eyelike intracystic nodules in RCC. Cyst fluid with hypointense signal in T1-weighted images and hyperintense signal in T2-weighted images. Circular isointense signal in T1- and T2-weighted images surrounding the nodule, and slight hypointense signal in T1-weighted image and slight hyperintense signal in T2-weighted images at the center of cyst. (a) nonenhanced coronal T1-weighted image; (b) coronal T2-weighted image; (c) axial T2-weighted image.
