Abstract :
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.
