Chronic expanding hematomas (CEHs) in the retroperitoneal space are rare disease. Since CEHs often develop huge masses, it is difficult to differentiated from malignant tumor. Here, we present a case of CEH in the retroperitoneal space. The lesion exhibited increased activity on 18F-fluordeoxyglucose positron emission tomography (FDG-PET). In the present case, the increased FDG uptake was showed only in the peripheral rim of the mass, and no other abnormal uptake was observed. The findings of our case and previously reported cases suggest that FDG uptake observed only in peripheral rim of the mass might be characteristic findings of CEHs.
腹膜后间隙慢性扩展性血肿（CEH）是一种罕见疾病。由于CEH常形成巨大肿块，因此难以与恶性肿瘤相鉴别。在此，我们报告一例腹膜后间隙CEH病例。该病变在18F-氟脱氧葡萄糖正电子发射断层扫描（FDG-PET）上表现为活性增加。在本病例中，FDG摄取增加仅显示在肿块的周边，未观察到其他异常摄取。我们病例及先前报道病例的结果提示，仅在肿块周边观察到的FDG摄取可能是CEH的特征性表现。
