Traumatic subarachnoid hemorrhage (SAH) is a common finding following traumatic brain injury. In some cases, it can be associated with hydrocephalus. This type of hemorrhage is mostly caused by the rupture of small vessels in the brain and is usually managed conservatively.
We present a case of a 60-year-old woman who presented with traumatic luxation of the eye following a fall. This resulted in diffuse SAH (Fisher grade IV) with associated hydrocephalus. We also report on 3 previous similar cases found in the literature. Avulsion of the ophthalmic artery was found to be the cause of the traumatic SAH. Apart from cerebrospinal fluid diversion using an external ventricular drain, the case was managed conservatively. There was no evidence of delayed clinical or radiologic vasospasm.
Traumatic avulsion of the ophthalmic artery may result in diffuse SAH, mimicking that of aneurysmal rupture. This case shows that management of early complications, such as hydrocephalus and seizures, should be the main aim. Surgical or endovascular treatment of the injured artery, however, would be unnecessary.

We present a case of ophthalmic artery (OA) traumatic avulsion, leading to a post-traumatic subarachnoid hemorrhage (SAH) with ventricular blood invasion and hydrocephalus, mimicking an internal carotid aneurysm rupture. This is the third case of such an event reported in literature and the first without orbital fractures and optic nerve avulsion. Conservative treatment was sufficient for the avulsion, but surgery was needed for the coexisting eye luxation. Traumatic OA avulsion is a rare but possible event and should be suspected in case of basal cisterns SAH, evidence of orbital trauma and CT angiogram or angiographic absence of opacification of the OA.
