Abstract

Introduction

Cranial irradiation is used both prophylactically and for the treatment of brain tumors. There are various complications associated with it. The rare complication of stroke-like migraine attacks after radiation therapy (SMART) syndrome usually occurs several years after radiation therapy but is a reversible phenomenon. It usually presents with headaches, seizures, or other focal neurological deficits concerning stroke or recurrence of the underlying disease.

Objectives

We aim to present two cases of SMART syndrome highlighting the typical presentation, imaging findings, and differential diagnosis. We also conducted the literature review since the early recognition of this rare delayed onset complication is crucial, given its self-limited course and to avoid misinterpretations of the cases.

Conclusion

Our extensive review favors MRI, CT, and prolonged EEG monitoring to rule out other differentials and showed that initiation of corticosteroid therapy and antiepileptic treatment were helpful in the resolution of symptoms and prevent recurrences. Therefore, future studies should be focused on early identification and management guidelines for SMART syndrome.
