Malignant peritoneal mesothelioma (MPeM) is a rare malignancy that accounts for approximately 10%-30% of all mesothelioma cases, with the more common type being pleural mesothelioma. In this case report, we describe an atypical presentation of MPeM in a 73-year-old female presenting with periumbilical swelling and subacute chest pain. Imaging demonstrated a large periumbilical mass and a posterior mediastinal mass encasing, but not obstructing, the esophagus. A brief literature review examining the broad range of clinical and imaging manifestations of MPeM is presented.
恶性腹膜间皮瘤（MPeM）是一种罕见的恶性肿瘤，约占所有间皮瘤病例的10%-30%，更常见的类型是胸膜间皮瘤。在本病例报告中，我们描述了一名73岁女性MPeM的非典型表现，其表现为脐周肿胀和亚急性胸痛。影像学检查显示脐周有一个大肿块，后纵隔有一个肿块包绕但未阻塞食管。本文简要回顾了MPeM广泛的临床和影像学表现。
