@entity3969 is the most common pediatric primary @entity703 and is highly responsive to surgery and chemotherapy. The role of radiotherapy has evolved in the last three decades from the use of stepwise incremental doses in all @entity1 to the current concept of added radiotherapy in advanced cases or in those with unfavorable pathology. To the authors' knowledge, this is the first case of a young @entity1 with prior history of @entity3969 and significant @entity353 due to radiation @entity3468 involving the abdominal vasculature. A 31-year-old @entity1 presented with a history of @entity353 and severe @entity3147 . An angiogram revealed that the aorta was occluded below the renal artery. The celiac artery and the superior mesenteric artery were occluded at the origin, and large intercostal collaterals reconstituted the pelvic circulation. She was initially treated with total parenteral nutrition (TPN) and underwent an infrarenal aortic bypass surgery. Histopathology of the aorta revealed intimal fibrocalcific thickening and changes consistent with radiation-induced @entity3468 . Later, she was readmitted with progressive @entity7752 . Despite intensive medical therapy, she died of @entity881 .
