Arachnoid Cyst Associated With Traumatic Chronic Subdural Hemorrhage in Children
Introduction:
It was reported that most arachnoid cyst (AC)-associated chronic subdural hematoma (CSDH) was spontaneous. However, AC with CSDH caused by trauma was extremely scarcely reported. In this paper, the authors reported a successful surgical treatment of a case of AC associated with CSDH after trauma.
Case Presentation:
A 15-year-old girl was admitted with headache and vomiting persisting for 3 days following a head injury received 1 month previously. Head magnetic resonance imaging (MRI) showed a left temporal AC and ipsilateral CSDH. Digital subtraction angiography (DSA) of the brain showed no vascular abnormalities. The patient underwent a left burr hole irrigation and drainage (BHID). The patient recovered well after surgery and was discharged 4 days later.
Clinical Discussion:
This event's pathogenesis is thought to be caused by vascular rupture around AC. It can not only occur spontaneously but also be caused by varying degrees of head trauma. Surgery is the most common and effective treatment, including BHID, partial/subtotal membrane resection, endoscopic fenestration, and so on.
Conclusion:
Arachnoid cyst (AC) with traumatic CSDH is an extremely scarce condition. Surgery is the most common and effective treatment. Moreover, it is necessary to perform DSA before surgery to rule out cerebral vascular malformations in children and adolescents.
