原发性肺肿瘤在小儿中少见,而其良性瘤中约一半是浆细胞肉芽肿(PCG),因肺PCG没有特异的临床表现及影象学特征,常在手术切除后才能确诊。具有瘤体组织钙化的肺PCG,其症状类似于前纵隔肿瘤。病例男,9岁,因反复咳嗽、气短1年,加重2天而急诊入院。曾用抗生素和支气管扩张剂治疗。体检:一般状态良好,胸部叩诊右下肺呈浊音,听诊右肺呼吸音减弱,可闻及水泡音及哮鸣音。实验室检查未见异常。胸部X线正侧位片见右前纵隔有较大的肿物,轮廓清晰,其内有形状及大小不等的钙化点;胸部增强CT(CECT)扫描,肿物邻近右纵隔,轮廓清晰,内有散在钙化点,肿物密度低于纵隔。术前诊断为纵隔畸胎瘤。
Primary lung tumors are rare in children, and about half of their benign tumors are plasmacytoma granulomas (PCG). Pulmonary PCG has no specific clinical manifestations and imaging features and is often diagnosed after surgical resection. PCG with calcified lung tissue has symptoms similar to those of anterior mediastinal tumors. Case of male, 9 years old, due to repeated cough, shortness of breath for 1 year, increased 2 days and emergency admission. Have used antibiotics and bronchodilators treatment. Physical examination: The general condition is good, the right lower lung of the percussion of the chest is dull, auscultatory right lung breath sounds weakened, can be heard and blisters and wheeze sounds. Laboratory tests showed no abnormalities. Chest X-ray is the lateral radiographs of the right anterior mediastinal large tumor, clear outline, which has a shape and size of calcification; chest enhanced CT (CECT) scan, the tumor adjacent to the right mediastinum, clear outline, within Scattered calcification, tumor density is lower than the mediastinum. Preoperative diagnosis of mediastinal teratoma.
