Inflammatory myofibroblastic tumor (IMT) occurring in the pancreas was rare and few clinical cases had been reported. The specificity of clinical presentation of IMT was lacked and its CT imaging manifestations were diverse. The enhanced CT images of a rare patient with IMT of the pancreas with liver metastases were presented to the readers, and the pathophysiological mechanisms associated with the CT imaging manifestations were briefly described, so as to enhance the readers’ understanding and knowledge of the CT imaging manifestations and raise the diagnostic awareness of the disease.
Inflammatory myofibroblastic tumor (IMT) involving stomach, liver, biliary tract, and peritoneal mesentery was very rare, nonspecific clinical manifestations and laboratory examination were the main reasons for the difficult preoperative diagnosis of IMT. An IMT case involving multiple systems and multiple sites of the abdomen was presented, the CT and MRI imaging signs and pathological basis of IMT were illustrated, so as to strengthen the understanding of IMT for clinicians and radiologists.
Schwannoma originating from the common bile duct is rare. We presented a patient who was diagnosed with biliary cystadenoma preoperatively and pathologically confirmed as a choledochal Schwannoma, analyzed the CT and MRI imaging manifestations, and illustrated its anatomical and pathological basis, and to improve the understanding of clinicians and radiologists for choledochal Schwannoma.
