Emergent stent-graft repair of a massive aortic pseudoaneurysm secondary to Behçet's disease in a child

Isolated Idiopathic Right Common Iliac Artery Aneurysm Presenting as Acute Appendicitis in a 9-Year-Old Girl: A Case Report and Literature Review

The prevalence of iliac artery aneurysms is extremely rare in children. The most common etiologies for developing an aneurysm in children are infections, inflammatory diseases, and trauma. An idiopathic or congenital etiology is the least common cause in the pediatric population. We report a case of a 9-year-old girl with no previous history of trauma, intervention, or family history of vascular diseases who presented with a sudden severe right lower quadrant pain suggesting appendicitis. Upon examination, a large tender pulsatile mass was felt in the right lower quadrant. Ultrasound and computed tomography scans revealed a large right common iliac aneurysm. The aneurysm was noted to have a high risk of rupture due to the sudden symptomatic presentation and its large size. Therefore, the patient underwent an urgent operation, during which an aneurysmal repair was performed with an interposition graft. Postoperative ultrasound imaging showed a patent graft and no residual aneurysm. The patient has been followed up for two years, and no complications were found.
