Large dumbbell-shaped solid cystic lesion in the left perimedullary cistern along the course of the left hypoglossal nerve appearing hyperintense on T2 (a, c) and iso- to hypo-intense on T1 (b). On post-contrast study, it showed heterogenous enhancement (d). Posteriorly, it was causing a mass effect over the medulla and cervico-medullary junction (e).
