Ruptured duodenal duplication cyst in a 58-year-old man who sustained blunt trauma in a fall down stairs. a Reformatted sagittal contrast-enhanced CT shows circumferential wall thickening of the cyst and a disruption in its anterior surface (arrow). b Axial CT shows retroperitoneal fluid in the right anterior pararenal space (white arrow). The duodenal lumen is narrowed and displaced medially due to inflammatory changes (black arrow). c Axial T2-weighted MRI shows stranding of the periduodenal fat on (arrows). d Axial T1-weighted MRI image shows a hyperintensity of the content of the lesion (*). The high signal intensity (more than muscle tissue), in a traumatic context, suggests an haemorrhagic transformation of the cyst. e Detail of the fiberoptic endoscopic study
