a Computed tomography scan without contrast showing irregular soft tissue mass (White arrow). The lesion had an uneven interior and was surrounded by a blurred fat gap. There were multiple spots of high density with clear margins in the upper right of the lesion. b-c Contrast-enhanced computed tomography showing multilocular changes of the lesion (White arrow), uneven enhancement of cystic wall, slight enhancement of adjacent duodenal wall, and multiple enlarged lymph nodes. d Abdominal computed tomography was reviewed 1 month after treatment. Computed tomography scan without contrast showing the postoperative change of local high-density imaging in the duodenum wall, the volume of the lesion (White arrow) gradually decreased, and the edge was clear, and no substantial changes in the multiple high-density shadow spots were seen
