Magnetic resonance imaging (MRI) demonstrated a hyperintense lesion without mass effect in the right cerebellar hemisphere with no supra tentorial pathology (Figure 1).
MRI showing interval increase in size of T2 and FLAIR hyperintense infiltrative signal intensity in the right middle cerebellar peduncle and right cerebellar hemisphere as well as a small new focus of FLAIR hyperintense signal intensity in the left cerebellar hemisphere parasagittal to midline.

Repeat MRI showed interval increase in size of T2 and FLAIR hyperintense infiltrative signal intensity in the right middle cerebellar peduncle and right cerebellar hemisphere as well as a small new focus of FLAIR hyperintense signal intensity in the left cerebellar hemisphere parasagittal to midline without enhancement, mass effect, or associated restricted diffusion (Figure 2).
