Case ReportsArterial spasm following perimesencephalic nonaneurysmal subarachnoid hemorrhage in a pediatric patient.
Perimesencephalic nonaneurysmal hemorrhage is a benign form of subarachnoid hemorrhages. This entity is well recognized as a distinct type of subarachnoid hemorrhage in adults. However, perimesencephalic nonaneurysmal subarachnoid hemorrhage in pediatric patients is not well recognized. ⋯ Cerebral carotid angiography performed on the tenth day of the posthemorrhagic period revealed severe vasospasm affecting the basilar artery. The patient, treated symptomatically, was discharged after improvement. One year later, magnetic resonance angiography revealed completely normal features.
