A 15-year-old girl with history of medulloblastoma was evaluated for headache and neurologic deficits 5 years after completion of initial radiation therapy and 3 years following completion of reirradiation. Neurologic examination was notable for new-onset left hemianopia, hemiparesis, and neglect. Magnetic resonance imaging showed extensive areas of cortical T2 prolongation and thickening involving the right parietal, occipital, and temporal lobes with associated extensive gyral enhancement. Upon spontaneous resolution of her weakness after 4 days, repeat magnetic resonance imaging showed resolution of the edema and gyral enhancement, suggestive of the diagnosis of stroke-like migraine attacks after radiation therapy (SMART syndrome). A review of SMART is provided in this case report.
