Perivascular epithelioid cell tumors (PEComas) constitute a rare subset of mesenchymal neoplasms classified by the World Health Organization in 2002. We present two cases of PEComas; the first is a cervical PEComa in a 35-year-old woman with no known past medical history who presented with a palpable pelvic mass; the second is an adnexal PEComa in a 39-year-old woman with a history of colitis who presented with abdominal pain and diarrhea. The rarity of these tumors has led to little information about imaging characteristics which we hope these two cases will help expand.
血管周上皮样细胞瘤（PEComas）是间叶性肿瘤中罕见的一类，于2002年被世界卫生组织分类。我们报告两例PEComas；第一例是一名35岁女性的宫颈PEComa，既往无已知病史，因可触及盆腔肿块就诊；第二例是一名39岁患有结肠炎病史的女性的附件PEComa，因腹痛和腹泻就诊。这些肿瘤的罕见性导致关于其影像学特征的信息很少，我们希望这两例病例将有助于拓展这方面的信息。
