摘要
目的探讨儿童胸膜肺母细胞瘤(PPB)的CT影像学表现。方法回顾性分析14例(15例次)经手术、病理学证实的儿童PPB的临床、病理学及影像学资料。结果 15例次患儿发病平均年龄(27.3±12.5)个月,临床表现为咳嗽14例次,发热8例次,呼吸困难8例次,腹痛1例次。Ⅰ型(囊性)3例次,Ⅱ型(囊实性)3例次,Ⅲ型(实性)9例次。病灶位于右侧10例次,左侧5例次。肿瘤来源于肺内5例次,来源于胸膜10例次。肿物平均直径为(11.86±2.94)cm。合并胸腔积液、肺不张12例次,胸膜增厚10例次。15例次均未见肋骨破坏及胸壁软组织浸润。纵隔淋巴结转移4例次,远处转移1例次。CT表现为巨大囊性、囊实或实性肿块,增强后肿瘤实性部分明显不均匀强化及延迟强化。结论 PPB的CT表现具有一定的特征性。
Objective To explore CT manifestations of pleuropulmonary blastoma（PPB）in children.Methods Fifteen cases of PPBs confirmed by surgery and pathology were retrospectively analyzed in terms of clinical data,pathology and imaging manifestations.Results The mean age of all cases was（27.3±12.5）months.The common chief complaints were upper respiration tract symptoms,8cases with fever,14 cases with cough,8cases with dyspnea and 1case with abdominal pain and thoracalgia.TypeⅠ（predominantly cystic）was 3cases,Type Ⅱ（cystic and solid）was 3cases,Type Ⅲ（pure solid）was 9cases.Tumors located in the left and right hemithoras were 5and 10 cases,and tumors originated from the lung and the pleura were 5and 10 cases,respectively.The average diameter of masses about（11.86±2.94）cm.In 15 cases,12cases associated with pleural fluid and pulmonary atelectasis,10 cases with pleural thickening of affected side.None of the cases with rob erosion and chest wall soft tissue damage,4cases were lymph nodes and 1case was kidney and retroperitoneal.PPBs showed a huge lesions of cystic,cystic and solid or solid mass,the solid part of the tumor was significantly heterogeneous enhancement and delayed enhancement.Conclusion PPB has certain CT image features in children.
