BACKGROUND
Lipoma is a benign mesenchymal tumor of soft tissue that occurs in almost all parts of the body where fat normally exists. Retroperitoneal lipomas are very infrequent condition with about 20 cases represented in the literature since 1980. They usually present as an abdominal mass or with pressure symptoms to adjacent organs.
CASE PRESENTATION
A 66-year-old, post-menopausal woman referred to Imam Hossein Medical Center due to abdominal pain. Abdominopelvic magnetic resonance imaging (MRI) revealed a large mass containing fat component without enhancement on the right side of the pelvis. Tumor markers were within normal ranges. The patient underwent laparotomy and a 12 cm retroperitoneal mass which was located on the iliopsoas muscle with extension into the inguinal canal was resected with pathology report of lipoma. There has been no recurrence after one year of follow-up since surgery.
CONCLUSION
In the differential diagnosis of retroperitoneal pelvic mass at all ages, lipoma should be considered as a rare cause.
背景
脂肪瘤是一种软组织良性间叶肿瘤，几乎发生于身体所有正常存在脂肪的部位。腹膜后脂肪瘤非常罕见，自1980年以来文献报道约20例。它们通常表现为腹部肿块或伴有对邻近器官的压迫症状。
病例报告
一名66岁绝经后女性因腹痛转诊至伊玛目侯赛因医疗中心。腹盆腔磁共振成像（MRI）显示盆腔右侧有一个含有脂肪成分且无强化的大肿块。肿瘤标志物在正常范围内。患者接受了剖腹手术，切除了一个位于髂腰肌上并延伸至腹股沟管的12厘米腹膜后肿块，病理报告为脂肪瘤。术后随访一年无复发。
结论
在各年龄段腹膜后盆腔肿块的鉴别诊断中，脂肪瘤应被视为一种罕见病因。
