Traumatic Hemorrhage from the Anterior Choroidal Artery

Bilateral large traumatic basal ganglia haemorrhage in a conscious adult: A rare case report

“…TBGH is thought to be caused by shearing injury of the lenticulostriate or anterior choroidal artery as a result of acceleration/deceleration forces [3,4,7]. Such shearing forces might occur in the basal ganglia region when a strong impact is applied to the vertex, forehead or occipital area and directed toward the tentorium.…”

A Viewpoint on Treatment of Traumatic Bilateral Basal Ganglia Hemorrhage in a Child: Case Report

“…A small amount of TBGH (<2 cm in diameter) can be considered as a hemorrhagic contusion 4). It can be related to diffuse axonal injury when it is associated with contusions and/or small hemorrhage in the corpus callosum, basal ganglia, tegmentum of pons, IVH, and acute brain swelling 11).…”

“…The pathophysiologic mechanism of unilateral TBGH is unclear, but is believed to occur from shear strain in ganglionic lesion 12). Mosberg and Lindenberg4) demonstrated a traumatic tear of a pallidal branch of anterior choroidal artery as the origin of pallidal hematoma in an autopsy case. Head injuries including traffic accidents associated with acceleration and deceleration forces with rotational movement traumatic dissection of perforating arteries, mainly the anterior choroidal artery or lenticulostriate artery, can cause basal ganglia hemorrhage 61012).…”

Unstable Chest Surgical Management in Pregnancy: Case Report and Literature Review

“…2 The sudden acceleration/deceleration forces at the time of injury result in shearing strain over the lenticulostriate and anterior choroidal vessels leading to bleeding. Mosberg and Lindenberg, 4 in an autopsy of fatal head injury patient, demonstrated massive hematoma in the improvement in all patients managed conservatively. Kimura et al, 13 Katz et al, 3 and Jang et al 7 have also reported favorable outcomes for TBGH with conservative management.…”
