Pelvic tumors that contain fat are common findings in women. Although the majority of these lipomatous tumors are benign cystic ovarian teratomas, other diseases should be considered in the differential diagnosis: malignant degeneration of a benign cystic ovarian teratoma, nonteratomatous lipomatous ovarian tumors, lipomatous uterine tumors, benign pelvic lipomas, and pelvic liposarcomas. Although these diseases are rare, their differentiation can be clinically significant. While most of these tumors are treated by surgical excision, asymptomatic lipomatous uterine tumors and benign pelvic lipomas may require no therapy. Additionally, correct identification of a malignant lipomatous tumor will affect both prognosis and surgical planning. The purpose of this essay is to illustrate the imaging findings of these conditions.
盆腔内含有脂肪的肿瘤在女性中较为常见。尽管这些脂肪瘤性肿瘤大多是良性囊性卵巢畸胎瘤，但在鉴别诊断时应考虑其他疾病：良性囊性卵巢畸胎瘤的恶性变、非畸胎瘤性脂肪瘤性卵巢肿瘤、脂肪瘤性子宫肿瘤、良性盆腔脂肪瘤和盆腔脂肪肉瘤。虽然这些疾病罕见，但它们的鉴别在临床上可能具有重要意义。虽然这些肿瘤大多通过手术切除治疗，但无症状的脂肪瘤性子宫肿瘤和良性盆腔脂肪瘤可能无需治疗。此外，正确识别恶性脂肪瘤性肿瘤将影响预后和手术规划。本文的目的是阐述这些疾病的影像学表现。
