Traumatic middle cerebral artery aneurysm: case report and review of the literature

Abstract

Traumatic intracranial aneurysms are rare. A case of traumatic middle cerebral artery aneurysm was presented. A 66-year-old man sustained a severe head injury in a bicycle accident. Serial computed tomography and angiography showed the delayed intracerebral hemorrhage caused by the traumatic middle cerebral artery aneurysm. The aneurysm was trapped and removed. Histological examination clearly revealed the pseudoaneurysm. Traumatic middle cerebral aneurysms were reviewed.

Hemorrhagic Progression of a Contusion after Traumatic Brain Injury: A Review

“…Unfortunately, there is ambiguity in the literature. ''Delayed intracerebral hematoma'' or DTICH may refer to cases that present many weeks after injury, when delayed hemorrhage may be due to a traumatic intracranial aneurysm (Horiuchi et al, 2007;Hossain et al, 2002;Kaplan et al, 2003;McFeeley et al, 1988;Yang et al, 2007). The term ''progressive hemorrhagic injury'' has been used to refer to progression of an epidural hematoma, subdural hematoma, intraparenchymal contusion or hematoma, or subarachnoid hemorrhage (Oertel et al, 2002).…”

A Rare Case of Posterior Communicating Artery Pseudoaneurysm Caused by Traumatic Head Injury

“…The hematoma organizes to form the outer wall of the aneurysm. Unlike berry aneurysms, TICAs typically do not have a neck, are more irregular in their dome contour, and are subject to delayed filling and emptying of the sac based on angiograms [4]. On the basis of anatomic location, we divided TICAs secondary to blunt brain injury into two categories: skull base and peripheral TICAs.…”

Traumatic aneurysm of the cortical middle cerebral artery

“…Traumatic middle cerebral artery aneurysms (TMCAA) are a subtype of TICA and in 93% of cases occur in the cortical segment of the MCA, usually in association with skull fracture 3. Owing to their location, 55% of TMCAA present with SDH 3…”
