Posttraumatic infarction in the territory supplied by the lateral lenticulostriate artery after minor head injury

Abstract

Children with minor head trauma who have normal findings on initial CT scan may rarely have basal ganglionic infarction resulting from arterial spasm or thromboembolism of the perforating arteries. Hospital admission and careful observation should be considered for patients with minor head injury and persistent neurologic deficits despite normal CT findings. Magnetic resonance study is valuable for the evaluation of posttraumatic infarction, differentiating from hemorrhagic diffuse axonal injuries.

Basal ganglia germinoma: Diagnostic value of MR spectroscopy and 11C-methionine positron emission tomography

“…The patient presented here showed a tumor distribution similar to that observed for brain infarcts around the lateral lenticulostriate artery, which can be triggered by a minor head trauma [8,9]. Partial recovery of the initial hemiparesis and the lactate peak on MR spectroscopy [10] were also compatible with such an etiology.…”

Pontine Infarction Induced by Injury of the Perforating Branch of the Basilar Artery After Blunt Head Impact -Case Report-

“…9,16) Axonal injury is occasionally associated with perforating branch injury, resulting in hemorrhage or infarction due to shearing force. 1,12) Therefore, shearing force to the paramedian branch of the basilar artery may have caused the cerebral infarction in this case.…”

“…Brain infarction following perforator injury, which also tends to occur following shearing force due to blunt head trauma, is thus more frequently reported in children 1,6,8,14) than in adults. 23) Furthermore, the cerebral hemisphere may be more vulnerable than the brainstem following shearing force, 17) as infarction of the basal ganglia due to perforator injury induced by shear stress 1,6,8,14) is more frequent than that of the brainstem 21) in children. Again, infarction due to perforator injury induced by shear stress of both basal ganglia and brainstem is extremely rare in adults in comparison to children.…”

Current status of infarction in the basal ganglia‑internal capsule due to mild head injury in children using PRISMA guidelines (Review)

“…It is noteworthy that most injuries are low-speed injuries. Most had a definite history of a fall from a low-altitude height, either from the lap of a mother, a chair, a bed, a table, fences, stairs or the child tripped while running (17,33,35,42).…”
