OBJECTIVE
The purpose of this study was to describe the imaging features of posttransplant lymphoproliferative disorder (PTLD) in pancreas transplant recipients.
CONCLUSION
The prominent image finding of PTLD in pancreas transplant recipients is diffuse allograft enlargement, an appearance that may be indistinguishable from the image findings of acute pancreatitis or transplant rejection. However, failure of response to immunosuppressive therapy, presence of intraallograft or extraallograft focal masses, or organomegaly may suggest the diagnosis of PTLD.
目的
本研究的目的是描述胰腺移植受者中移植后淋巴细胞增生性疾病（PTLD）的影像学特征。
结论
胰腺移植受者中PTLD的突出影像学表现是移植胰腺弥漫性肿大，这种表现可能与急性胰腺炎或移植排斥反应的影像学表现难以区分。然而，对免疫抑制治疗无反应、移植胰腺内或外存在局灶性肿块或器官肿大可能提示PTLD的诊断。
