Abstract:
Portal vein aneurysm is a rare vascular disorder, particularly in the pediatric population, with relatively few cases reported in the literature. The most frequent complication of portal vein aneurysm is thrombosis, which may lead to diagnostic uncertainty as it can resemble a tumor. Therefore, it is important to recognize this entity and its imaging features for accurate diagnosis. We present a case of a portal vein aneurysm in an adolescent boy, complicated with thrombosis, and report radiological findings, treatment, and short-term follow-up.

Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
