A 65-year-old woman with a remote history of right frontal low-grade astrocytoma resection and adjuvant radiotherapy (RT) at the age of 15 years underwent routine electroencephalography (EEG). She had experienced RT-induced infratentorial and supratentorial cavernomas and right occipital angiomatous meningioma. The patient reported a 5-year history of episodic right frontal migraine-type headaches, paroxysmal flashes of light in the left visual field, and transient left arm paresthesia. She had visited the emergency department twice for transient left hemibody weakness, attributed to a possible right transient ischemic attack (TIA). Contrast-enhanced T1 magnetic resonance imaging of the brain revealed cortical edema, T2-weighted fluid-attenuated inversion recovery hyperintensity, and gyriform enhancement (), along with hyperperfusion in the right temporoparietooccipital and posterior frontal lobes. The clinical and imaging features were compatible with stroke-like migraine attacks after radiation therapy (SMART) syndrome.
