Abstract:
Traumatic intracranial aneurysms are rare lesions that occur after blunt or primarily penetrating mechanisms. These are extremely fragile vessel injuries associated with significant morbidity and mortality, especially after rupture. Disease natural history, surveillance strategies, and management are based on small case series. Here we present a case of a 29-year-old male with a large epidural hematoma after blunt trauma, who underwent emergent surgical intervention. Three months postoperatively, he presented with unusual cerebral bleeding. Clinical suspicion prompted a conventional angiogram, which diagnosed a ruptured cortical traumatic intracranial aneurysm. The patient was urgently treated by surgical clipping with a good outcome.
