Endometriosis is a benign disease characterized by the implantation of functional endometrial tissue in ectopic locations. We present a case of a 42-year-old woman with widespread endometriosis that mimicked ovarian malignancy on FDG PET/CT. Increased FDG uptake was observed not only in the right ovary, but also in the liver capsule, perihepatic nodules, greater omentum, and the mesentery. This case indicates that widespread endometriosis may be a cause of multiple FDG uptakes in women of reproductive age and should always be kept in mind in the differential diagnoses of suspicious malignancy.
子宫内膜异位症是一种良性疾病，其特征是功能性子宫内膜组织在异位部位的植入。我们报告了一例 42 岁女性，其广泛的子宫内膜异位症在 FDG PET/CT 上模拟卵巢恶性肿瘤。不仅在右侧卵巢，而且在肝包膜、肝周结节、大网膜和肠系膜上均观察到 FDG 摄取增加。本例表明，广泛的子宫内膜异位症可能是生育年龄妇女多个 FDG 摄取的原因，在可疑恶性肿瘤的鉴别诊断中应始终牢记这一点。
