Traumatic aneurysm of the callosomarginal artery

Traumatic intracranial aneurysm: A brief review

“…8 Distal anterior cerebral arteries are also prone to traumatic aneurysm formation because of their proximity to the stationary falcine edge. 10 In penetrating intracranial injury, the aneurysm is usually the result of direct injury to the vessel by the missile itself, a bone fragment, or a surgical procedure. 4,6 The clinical presentation of TICA is variable.…”

“…Since the CT scan has replaced cerebral angiography as the neuroradiological investigation of choice in acute head injury, the early diagnosis of intracranial aneurysms may have become less common and difficult. 4,10 Although CT angiography has improved significantly over the past few years as a non-invasive screening method to detect intracranial aneurysms, it is not sensitive enough to replace digital substraction angiography. 12,13 Conventional cerebral angiography thus remains the reference standard in the diagnostic work-up of intracranial aneurysms and it should be obtained in the setting of all severe head injuries.…”

“…These include a poorly defined neck, irregular contour of the aneurysm, an unusual location (at a peripheral vessel rather than at a major proximal branching point), and delayed filling and emptying of the aneurysm. 6,10 The timing of angiography is still controversial. Some authors believe that angiography performed within hours of injury may be normal because the aneurysm take time to develop.…”

“…Arterial contusion by the anterior clinoid process causes supraclinoid internal cerebral artery pseudoaneurysms 14)15). Distal anterior cerebral arteries might be injured by the proximal falcine edge 16). Cortical artery aneurysms commonly form because of an overlying skull fracture 21)…”

“…1,6,7 They can occur following penetrating as well as blunt head injury. [8][9][10][11][12] However, penetrating head injury is a more common cause of TICA formation than blunt head injury. 2,[12][13][14][15] Iatrogenic trauma has also been reported as a cause for TICAs.…”
