A 31-year-old female with lymphoma was incidentally found to have a left retroperitoneal lymphangiomyomatosis (LAM). The tumor was proved by pathology and immunohistochemical study of the tissue specimen obtained by ultrasound-guided core needle biopsy. The characteristic sonographic, computed tomographic, magnetic resonance imaging, and positron emission tomographic (PET) features of this unusual lesion were described. It was managed conservatively and remained stable on 2-year follow-up study. LAM should be considered in the differential diagnoses in cases of a retroperitoneal solid mass with cystic components.
一名31岁的淋巴瘤女性患者偶然发现患有左腹膜后淋巴管肌瘤病（LAM）。通过超声引导下的粗针活检获得的组织标本经病理及免疫组化研究证实了该肿瘤。描述了这种不寻常病变的特征性超声、计算机断层扫描、磁共振成像和正电子发射断层扫描（PET）表现。对其进行了保守治疗，在2年的随访研究中病情保持稳定。对于具有囊性成分的腹膜后实性肿块病例，鉴别诊断时应考虑LAM。
