Pediatric Traumatic Pericallosal Artery Aneurysm.

OBJECTIVE

The present investigation is geared towards an in-depth examination of the clinical characteristics, therapeutic approaches, and pertinent considerations associated with traumatic pericallosal artery aneurysms in children.

METHODS

A retrospective analysis was conducted on the diagnosis and treatment process of a case of pediatric traumatic pericallosal artery aneurysm resulting from pediatric traumatic brain injury, complemented by a comprehensive review of the relevant medical literature.

RESULTS

The patient presented with an acute epidural hematoma and cerebral herniation, necessitating the execution of epidural hematoma evacuation and decompressive craniectomy with the removal of the bone flap. The initial computed tomography angiography (CTA) did not reveal any intracranial aneurysms. However, 19 days following the surgical intervention, the patient experienced sudden coma and cerebral herniation, requiring reoperation. Postoperative digital subtraction angiography (DSA) confirmed the presence of a traumatic pericallosal artery aneurysm, which was managed through intracranial aneurysm embolization, culminating in an unfavorable prognosis.

CONCLUSION

Pediatric traumatic pericallosal artery aneurysms are frequently nonspecific in clinical and radiologic manifestations, leading to the potential for missed diagnoses and severe consequences. For patients under suspicion of harboring such aneurysms, early DSA confirmation is essential. In instances of negative preliminary findings, a repeat DSA may be deemed necessary to exclude delayed-onset aneurysms. Upon diagnosis, prompt surgical or endovascular intervention is warranted.
