Myelolipomas are rare benign tumors that contain a mix of fatty and hematopoietic tissues. These tumors are frequently seen in the adrenal glands. While extra-adrenal myelolipomas are extremely rare, once identified, they are commonly found in the retroperitoneum--particularly the presacral region. Because of the fat content, these tumors can be easily mistaken for retroperitoneal liposarcomas. We are presenting a case of a 44-year-old female with a pathology proven case of retroperitoneal extra-adrenal myelolipoma that was initially diagnosed by imaging as a retroperitoneal liposarcoma. In this case report, the clinical presentation, imaging findings, operative details and histopathology features are illustrated.
肾上腺髓质脂肪瘤是一种罕见的良性肿瘤，由脂肪组织和造血组织混合构成。这些肿瘤常见于肾上腺。肾上腺外髓质脂肪瘤极为罕见，一旦发现，通常位于腹膜后，尤其是骶前区域。由于其脂肪成分，这些肿瘤很容易被误诊为腹膜后脂肪肉瘤。我们报告一例44岁女性患者，经病理证实为腹膜后肾上腺外髓质脂肪瘤，最初经影像学检查诊断为腹膜后脂肪肉瘤。本病例报告阐述了临床表现、影像学表现、手术细节及组织病理学特征。
