Contrast-enhanced MRI of the head and spine

Gadolinium-enhanced, fat-suppressed, 3 mm axial T1-weighted images of the brain showing: abnormal area of enhancement within the left cerebellar hemisphere (black arrow) and abnormal enhancement of the left cochlea basal turn (red arrow; A); and abnormal enhancement within the left cerebellar hemisphere (black arrow), right cochlea basal turn (red arrow), anterior genu of the tympanic segment of the left facial nerve (blue arrow), and focus of enhancement within the left internal auditory canal (orange arrow; B). Gadolinium-enhanced 4 mm sagittal T1-weighted image of the lumbar spine showing enhancement involving the surface of conus and along the cauda equina (green arrow; C).
