Abstract

Stroke-like migraine attacks after radiation (SMART) syndrome is a rare and late complication of cerebral radiotherapy of unknown pathophysiology. It is characterised by hemicranial headache associated with persistent unilateral focal neurological signs and, occasionally, epileptic seizures. An increase in the frequency of SMART syndrome can be attributed to an increase in the survival rate of patients undergoing radiation therapy This study details the case of a 60-year-old woman with a history of small-cell lung carcinoma, who, in her late forties, was treated with prophylactic cranial irradiation. She presented at the emergency room with acute onset of global aphasia, lethargy and headache that started a few days before.
