FIG 2. Images in second patient with a solid cerebellar tumors that progressed to enlarging cysts with the subsequent development of symptoms.
A, Contrast-enhanced T1-weighted MR image shows an enhancing nodule in the right cerebellar hemisphere (arrow). (500/11 [TR/TE])
B, Image obtained 15 months later shows a large cyst associated with this nodule. Cerebellar symptoms necessitated surgical excision of this tumor. (460/13)
C, Follow-up contrast-enhanced MR image obtained 44 months after the initial study shows a new, small, enhancing nodule (arrow) and postsurgical change. (360/13)
D, Three years later, another contrast-enhanced MR image (D) shows that this nodule has increased in size. Also shown are two new, smaller nodules. (360/13)
E, Two years later, a STIR image reveals that a large cyst is now associated with this tumor. The patient experienced additional cerebellar symptoms, and further surgery was performed to remove this second tumor. (4400/96)
