“…Blunt brain injury could lead to formation of traumatic aneurysms around the cerebral falcine edge and cerebellum tentorium, but not in the trunk or sub-cortical branches of the middle cerebral artery. On the other hand, cortical artery aneurysms develop beneath an overlying skull fracture [1,2]. In our case, P-com pseudoaneurysm is formed due to disrupted vessel of P-com artery caused by sudden stretching during impact.…”

“…10) Moreover, infraclinoid ICA and basilar artery aneurysms are commonly associated with skull base fractures. 3) The possible mechanism for the formation of the traumatic ophthalmic artery aneurysm was not fully understood. After originating from the ICA, the ophthalmic artery runs under the optic nerve and penetrates the dural sheath of the optic nerve in the floor of the optic canal.…”

“…TICAs occasionally regress in size, or spontaneously disappear, 4,9,10) but have a high incidence of rupture. 1,3) Therefore, surgery or endovascular treatment is necessary as soon as practicable after the diagnosis of TICA. In our case, the aneurysm originated at the peripheral portion of the ophthalmic artery near the dural penetration point, and the patient had already lost sight in his left eye.…”

A 42-year-old male presented with a rare case of delayed aneurysmal formation of the intracranial ophthalmic artery after closed head injury manifesting as subarachnoid hemorrhage. Initial magnetic resonance angiography revealed no aneurysmal formation, but angiography 7 days after the injury demonstrated an intracranial ophthalmic artery aneurysm. Follow-up computed tomography angiography demonstrated enlargement of the aneurysm. The aneurysm was successfully treated by surgical resection. Histological examination revealed that the aneurysm was a pseudoaneurysm. Traumatic intracranial aneurysm (TICA) is rare and usually occurs in the peripheral arteries of the cerebral circulation or the basal portion of the internal carotid artery. The present case shows that failure to demonstrate an aneurysm on the initial angiography in the acute stage does not exclude the presence of traumatic aneurysm. This case clearly shows the time course of development of a TICA of the ophthalmic artery after closed head injury.

CasesTraumatic intracranial aneurysm following blunt head injury is uncommon but can be induced by extension of skull base fracture and causes unexpected hemorrhagic complications. We present two cases of traumatic intracranial aneurysm in the paraclinoid area that was revealed by delayed massive epistaxis. Lack of initial neurological deficits omitted screening for cerebrovascular injury.OutcomeInternal trapping was carried out using endovascular techniques in both cases, with extracranial–intracranial bypass in one case. No recurrent bleeding occurred in either case.ConclusionTo prevent unexpected delayed life‐threatening hemorrhagic accidents, careful assessment of skull‐base fracture is prerequisite, even in cases of mild facial injury.
