Mesenteric lipomas are rare tumors, with fewer than 50 reported cases. A 42-year-old woman with no significant medical history was referred to our hospital for surgical removal of submucosal myoma and a left ovarian tumor that was diagnosed at a different clinic. Preoperative magnetic resonance imaging findings suggested a differential diagnosis of fibroma, Brenner's tumors, and mature teratomas; however, the intraoperative findings showed a sigmoidal mesenteric tumor adherent to the left ovary. Pathological examination revealed degenerated adipose tissue, and the patient was diagnosed with sigmoidal mesenteric lipoma. When a degenerated sigmoidal mesenteric lipoma is adherent to the ovary, it must be differentiated from an ovarian tumor.
肠系膜脂肪瘤是罕见肿瘤，报告病例少于50例。一名42岁无重大病史的女性因黏膜下肌瘤和在另一家诊所诊断出的左侧卵巢肿瘤被转诊至我院进行手术切除。术前磁共振成像结果提示纤维瘤、勃勒纳瘤和成熟畸胎瘤的鉴别诊断；然而，术中发现一个乙状结肠系膜肿瘤附着于左侧卵巢。病理检查显示脂肪组织退变，该患者被诊断为乙状结肠系膜脂肪瘤。当退变的乙状结肠系膜脂肪瘤附着于卵巢时，必须与卵巢肿瘤相鉴别。
