Non-infected postoperative collections in a 71-year-old man following PD for duodenal adenocarcinoma, complicated by intraoperative haemorrhagic shock. During prolonged hospitalisation, unenhanced (a) and postcontrast (b, c) CT images showed “saddlebag”-shaped retroperitoneal collection (*) with homogeneous fluid attenuation, thin walls. Note usual appearance of the MJL (arrows), scanty mesenterial fluid (+), drainage still in place (thick arrows). The patient ultimately recovered without additional procedures
