Calcified abdominal aortic aneurysm in a 12-year-old boy

Area of Science:

• Vascular Surgery
• Pediatric Cardiology
• Radiology

Background:

• Aneurysmal disease is rare in children, often linked to specific causes like genetic disorders, infections, or trauma.
• Idiopathic cases, without a clear cause, are even less common in the pediatric population.
• Abdominal aortic aneurysms (AAAs) are particularly uncommon in children, with very few documented cases.

Observation:

• A 12-year-old boy presented with an isolated infrarenal abdominal aortic aneurysm.
• The aneurysm exhibited dense intramural calcification, a rare finding in pediatric cases.
• The patient also had sterile mesenteric lymphadenopathy, an associated finding not previously reported.

Findings:

• This case represents one of the few documented instances of abdominal aortic aneurysm in a child with dense intramural calcification.
• The co-occurrence of sterile mesenteric lymphadenopathy with an abdominal aortic aneurysm in a pediatric patient is unprecedented.
• The etiology of the abdominal aortic aneurysm and associated lymphadenopathy in this case remains idiopathic.

Implications:

• This case highlights the importance of considering rare vascular pathologies in pediatric patients, even without apparent risk factors.
• The unique presentation may prompt further research into the underlying mechanisms of idiopathic aneurysms in children.
• Further investigation is needed to understand the relationship between aortic calcification, mesenteric lymphadenopathy, and aneurysmal disease in the pediatric population.
