Superficial temporal artery-middle cerebral artery bypass surgery in a pediatric giant intracranial aneurysm presenting as migraine-like episodes.

Introduction: Aneurysms of the intracranial arteries in the pediatric population are reportedly rare. There is a male predominance, association with connective tissue disorders, as well as bacterial, mycotic infections, and trauma.

Results And Discussion: Common sites of presentation are the internal carotid artery bifurcation, posterior circulation, and distal segment of middle cerebral artery. Clinical manifestations can vary from seizures and subarachnoidal hemorrhage to headache, irritability, lethargy, vomiting, or focal motor deficits. Current treatment modalities encompass endovascular or surgical approach.

Conclusion: We present a case report on an 11-year-old girl with migraine-like episodes due to an underlying giant fusiform middle cerebral artery aneurysm treated successfully with two superficial temporal artery-middle cerebral artery bypasses.
