Final Pr. ID: Poster #: EDU-006

Abdominal aortic pathology is uncommon in the pediatric population. It is a complex clinical condition that can range from aneurysms to stenosis and can present in the emergency department as a life-threatening condition or as an incidental finding in elective studies. As radiologists, knowing the underlying conditions of abdominal aortic pathology can help clinicians narrow the differential diagnosis and provide early and focused treatment, as most of these cases represent a therapeutic dilemma. The purpose of this educational exhibit is to overview the embryology and normal anatomy of the abdominal aorta and to provide a comprehensive review, through cases, of the different causes of abdominal aortic aneurysms and middle aortic syndrome.

This case-based, pictorial, educational exhibit will:
1. Examine the predisposing conditions of thoracic aortic aneurysm (TAA) in children
2. Illustrate the histopathologic and imaging features of these conditions
3. Demonstrate proper technique for measuring and reporting aortic dimensions in children
4. Review treatment options for TAA and how treatment depnds on the underlying disease and imaging findings

Awareness of abdominal aorta abnormalities in pediatric patients is essential for appropriate diagnosis and management of the patients suffering from these conditions. Due to a nonspecific presentation, and sometimes being asymptomatic earlier in life, imaging has an important role in diagnosis of these abnormalities. Aneurysm and dissection are excluded, as they are not specific to children and with few exceptions mostly present in older patients.
We review the clinical presentation and show imaging findings of mid aortic syndrome, Takayusu arteritis, rare entities such as idiopathic infantile arterial calcification. Also we show imaging of the anatomic variants of the distal aorta such as middle sacral artery, persistent sciatic artery, abdominal aorta coarctation and blind ending aorta, with a short review of embryologic development of abdominal aorta. These anomalies are not common, however if remain undiagnosed might have serious consequences.

-Midaortic syndrome is an uncommon disease with progressive narrowing of the abdominal aorta and its major branches, typically involving interrenal segment of the aorta; it affects mostly children and young adults, the cause is not clear, might be the result of an intrauterine insult to the intima and subintimal tissues. Aside from diagnosis, imaging has a major role in endovascular treatment of mid aortic syndrome.
-Takayusu arteritis, also predominantly involves aorta and its major branches of younger patients, with strong female predominance, and frequently found in Asian patients. Destruction of arterial medi leads to aneurysm formation and uncommonly rupture of the involved artery.



-Idiopathic infantile arterial calcification, a rare entity presenting with extensive calcification and stenosis of large and medium sized arteries, usually leads to early death from coronary artery occlusion.
-The aortoiliac variants are rare and not commonly discussed in the imaging literature. Some anomalies might be asymptomatic in young ages, but might complicate surgeries like heart, renal transplant, or hip surgery and increases the risk of morbidity and mortality. Some of these anomalies such as persistent sciatic artery need long term follow-up, given the possibility of aneurysmal degeneration.
