Fig. 1From: Primary intracranial germ cell tumour originating from right brachium Pontis with hypertrophic Olivary degeneration: a case reportAxial T1 (a), T2 (b), and T1-weighted contrast-enhanced (c) MR images demonstrate an expansile ill-defined patchy lesion involving the right side of the middle cerebellar peduncle and dentate nucleus (arrows) as well as the displacement of the fourth ventricle. However, the ipsilateral facial nerve (black arrowhead) and vestibulocochlear nerve (white arrowhead) were not affected. The fused PET image (d) of the 18F-FDG PET/CT scan presents a decreasing metabolic lesion (SUVmax = 6.3) in the right brachium pontis that involves the ipsilateral cerebellar dentate nucleus (arrows)Back to article page
