SMART Syndrome Identification and Successful Treatment

We report a 41-year-old male patient admitted to our emergency room with a reduced level of consciousness and global aphasia. One month prior to admission, he started with frequent headache attacks of moderate intensity and paroxysmal behavioral alterations, advancing to confusion, gait instability, language impairment, and somnolence. He had a history of medulloblastoma treated with surgical resection followed by craniospinal irradiation 21 years before symptom onset. After excluding more frequent causes for the patient ’s symptoms along with a suggestive image pattern, we started treatment for SMART syndrome with high-dose corticosteroid and calcium channel blocker verapamil. The patient gradually improved his level of consciousness and recovered from aphasia and gait instability without new seizures or neuropsy chiatric symptoms. Follow-up brain magnetic resonance imaging showed resolution of the typical findings. This case displays a successful clinical evolution of a patient treated for SMART syndrome in which identification of previous radiation treatment, exclusion of other etiologies, and prompt treat ment institution were key for effectively tackling this disease.Case Rep Neurol 2021;13:40 –45
