Key Words: CT Pseudoaneurysm Aortic arch
A 57-year-old woman was admitted after ingesting a fish bone. Chest CT scans showed a pseudoaneurysm of aortic arch caused by penetration of a fish bone (Figs. 1 and 2
). The patient was operated on and pathologic evaluation by microscopy revealed fibrotic-granulation tissue, which confirmed the diagnosis of pseudoaneurysm.
