Peripheral primitive neuroectodermal tumors (PNET) are extremely uncommon, malignant neoplasms affecting mostly children and young adults. We retrospectively reviewed the clinical data and radiological studies of four such cases. All cases were pathologically proven. Plain films, US, and CT scans were used. The youngest child had a huge pelvic tumor and two adolescents each had a chest wall (Askin) tumor. The fourth patient had a most unusual location of the PNET in the anterior mediastinum. The CT findings are emphasized. We emphasize that the markedly abnormal CT findings are not specific for PNET.
外周原始神经外胚层肿瘤（PNET）极为罕见，是主要影响儿童和年轻人的恶性肿瘤。我们回顾性分析了4例此类病例的临床资料和影像学研究。所有病例均经病理证实。使用了平片、超声和CT扫描。最年幼的患儿有一个巨大的盆腔肿瘤，两名青少年各有一个胸壁（Askin）肿瘤。第四例患者的PNET位于前纵隔，位置极为特殊。文中强调了CT表现。我们强调，CT表现明显异常并非PNET所特有。
