Images 1 & 2: Axial T2 weighted images of the cerebellum show high
signal areas at the medial aspect of the Lt cerebellum involving the
Lt vermis and Lt superior and middle cerebellar peduncles.
Minimal mass effect on the fourth ventricle is seen.
Images 3 & 4: Sagittal T1 weighted images of the brain demonstrate
the lesion as hypointense area involving only the anterosuperior
aspect of the Lt cerebellum with a wedge shape appearance.
Images 5 & 6: MR angiogram of brain MIP images reveal a
poorly delineated distal basilar artery. Both vertebral arteries
and proximal basilar artery show normal flow signal. (T. Lai)
