Abstract

Post-transplant lymphoproliferative disease (PTLD) is a major cause of morbidity and mortality following both solid organ and haematopoietic stem cell transplantation. PTLD has a broad range of manifestations with extranodal involvement more common in the abdomen than nodal involvement. Fludeoxyglucose positron emission tomography/CT (FDG-PET/CT) is sensitive and specific to detect PTLD and can upstage or detect occult PTLD compared with conventional CT imaging. As functional imaging, FDG-PET/CT also has a role in monitoring treatment response. In this pictorial essay, we will discuss the role of FDG-PET/CT in the diagnosis and staging of abdominal PTLD and describe the advantages of functional imaging in assessing response to therapy.

摘要

移植后淋巴细胞增生性疾病(PTLD)是实体器官移植和造血干细胞移植后发病和死亡的主要原因。PTLD有广泛的表现,结外受累在腹部比淋巴结受累更常见。氟脱氧葡萄糖正电子发射断层扫描/计算机断层扫描(FDG-PET/CT)对检测PTLD敏感且特异,与传统CT成像相比,可使PTLD分期升高或检测出隐匿性PTLD。作为功能成像,FDG-PET/CT在监测治疗反应方面也有作用。在这篇影像论文中,我们将讨论FDG-PET/CT在腹部PTLD诊断和分期中的作用,并描述功能成像在评估治疗反应中的优势。
