Malignant Glioma in the Cerebellum Presenting as Multiple Small Lesions
Magnetic resonance images (MRIs) of the patient before biopsy. (a-d) Gd-enhanced T1-weighted images (Gd-T1WI) showing three separate lesions in the cerebellum: the lesion in the left cerebellum near the vermis with relatively regular enhancement (a), the lesion with the similar size in the right cerebellum with ring enhancement (b, arrowhead), and the tiny lesion in right cerebellum located far from two lesions (b, c, d, arrow). T2-weighted images (T2WI) showing peritumoral edema around two lesions (e, f, g), but no edema around the tiny lesion (f, arrow). FLAIR showing no clear connection of the tiny lesion to other two lesions (h, arrow).
