Brain magnetic resonance imaging (MRI) with and without contrast showed left cerebellar lesion measuring 3.6 x 3.2 x 2.9 cm with high T1 signal intensity, low T2 signal intensity, and low gradient echo sequence signal intensity with peripheral and mild internal enhancement, and a significant amount of surrounding vasogenic edema, ipsilateral transtentorial herniation, and obliteration of the fourth ventricle (Figure 1).
Follow-up MRI brain at 1 year showing evidence of prior resection of the left cerebellar mass with no recurrence of metastatic lesion or new metastasis.
