Angiolipoleiomyoma (ALLM) is a rare hamartomatous tumor of mesenchymal origin composed of smooth muscle, mature adipose tissue, and blood vessels in various proportions. Because of its histologic similarity to renal Angiomyolipoma (AML), it is also called uterine angiomyolipoma. Preoperative diagnosis of uterine ALLM is very challenging due to its uncommon incidence and absence of established characteristic imaging findings.
A 50-year-old multiparous female patient visited our institution for gynecologic screening. Transvaginal Sonography (TVS), Abdominopelvic Computed Tomography (CT), and pelvic Magnetic Resonance Imaging (MRI) revealed large well-defined masses involving the posterior uterine wall with rectal indentation. The patient underwent a total abdominal hysterectomy for this tumor and the histopathological diagnosis was uterine ALLM.
This report would contribute to understanding and establishing the radiologic findings of the uterine ALLM. Considering the benign characteristics and favorable prognosis of this rare tumor, familiarity with its imaging findings by radiologists will guide clinicians in better patient management and prevention of unnecessary radical surgery.
血管脂肌瘤（ALLM）是一种罕见的间叶组织来源的错构瘤，由平滑肌、成熟脂肪组织和不同比例的血管组成。由于其组织学上类似于肾脏血管平滑肌脂肪瘤（AML），也被称为子宫血管平滑肌脂肪瘤。由于其发病率低，且缺乏明确的特征性影像学表现，因此术前诊断子宫 ALLM 极具挑战性。
一位 50 岁的多产妇患者因妇科筛查就诊于我院。经阴道超声（TVS）、腹部盆腔计算机断层扫描（CT）和盆腔磁共振成像（MRI）显示，后子宫壁有大而界限清楚的肿块，伴有直肠凹陷。患者因该肿瘤接受了全子宫切除术，组织病理学诊断为子宫 ALLM。
本报告有助于了解和建立子宫 ALLM 的影像学表现。鉴于这种罕见肿瘤具有良性特征和良好的预后，放射科医生熟悉其影像学表现将有助于临床医生更好地管理患者并预防不必要的根治性手术。
