Periaortic CT findings of INAA. a Axial CECT image of a 58-year-old female patient demonstrates enhancing periaortic soft-tissue mass and fat stranding surrounding the multilobulated infrarenal aneurysm. b Axial CECT image of a 69-year-old male patient reveals a group of periaortic lymph nodes and fat stranding adjacent to the level of an infrarenal aneurysm. Left perinephric space involvement of INAA is also evident. c Axial CECT image of a 57-year-old female patient reveals a suprarenal aneurysm with periaortic soft-tissue mass and surrounding hypodense fluid extending to the peritoneal and retroperitoneal spaces. d Axial CECT image of a 62-year-old male patient shows periaortic soft-tissue mass with a few ectopic gas bubbles in the infrarenal aneurysm.
