Patient Data

Age: 55 years
Gender: Male
MRI

There is a right intra-axial cerebellar mass measuring 4.5 x 4 x 3.5 cm. It displays a low signal on T1, iso-to high signal on FLAIR, and inhomogeneous high signal on T2 with heterogeneous enhancement on postcontrast sequences and elevated rCBV on MR perfusion. Numerous tortuous vessels coursing over the surface and within the mass well visualized on FLAIR and T2 sequences. The adjacent transverse and sigmoid sinuses are patent. Surrounding vasogenic edema with tonsillar herniation and mass effect on the 4th ventricle and brainstem. Dilated 3rd and lateral ventricles with transependymal edema, in keeping with obstructive hydrocephalus.
