SMART syndrome. A 31-year-old male with a history of posterior fossa atypical teratoid rhabdoid tumour resected and radiated 10 years prior, now presents with persistent headaches, visual field deficits, and 1 day of word-finding difficulties. MRI images demonstrate gyriform thickening and a high T2 FLAIR signal involving much of the posterior cortex of the left temporal, parietal, and occipital lobes (arrow). There is associated mild diffusion restriction (arrowhead) and gyriform enhancement (bracket). Follow-up EEG demonstrated no epileptiform activity and symptoms subsequently resolved. Imaging findings and clinical course compatible with SMART syndrome
