Collapsed loop vs tumor recurrence. The MRI role. 62-year-old female patient during routine follow-up after pancreaticoduodenectomy due to pancreatic adenocarcinoma three months early. (a, c, e) Axial and coronal view contrast-enhanced CT scan. Homogeneous fluid collection (asterisk) in the surgical bed and related to an ill-defined soft tissue enhancing image with peripheral fat stranding associated (dotted arrows). Coronal view denotes a pseudo-mass image (arrowhead in c). Collapsed loop versus inflammatory changes were suggested as possible diagnosis, so strict control was indicated. (b, d, f) MRI performed two months later. Prior collection complete resolution. The ill-defined image related to the hepatic hilum is now better defined as the collapsed loop due to their fluid content and intestinal folds (dotted arrow). Coronal view denotes the blind portion of the afferent loop as the previously described pseudo-mass image (arrowhead in f)
