TRAUMA-INDUCED ARTERIAL ANEURYSM IN CHILD HOOD - REPORT OF A CASE ANDREVIEW OF THE LITERATURE

We report a case of calloso-marginal artery aneurysm in a 3 year old c hild, revealed 3 weeks after a craniocerebral trauma with frontal emba rrure, by a sudden subarachnoidal hemorrhage syndrome with loss of con sciousness and coma. The CT scan confirmed the subarachnoid hemorrhage in all the basal cisterns, with an interhemispheric subdural hematoma . The carotid angiography showed a right calloso-marginal aneurysm. Th e child has been operated (coagulation of the artery and excision of t he false aneurysm. We studied the mechanism of pediatric post-traumati c aneurysm, the histological and clinical presentation emphasizing the necessity of a complete neuroradiological exploration when new neurol ogical symptoms develop after head trauma. Neurosurgical and/or endova scular neuroradiological treatment is mandatory.
