作者报告100例支原体肺炎的临床和X线表现。该病临床表现不一,可影响肺上叶或下叶,单或双侧,并可伴有胸腔积液,胸部X线表现为肺段实变或弥漫性网状结节型浸润,作者发现有二种不同临床-X线征群: 第1组48例平均年龄26岁,表现为急性肺炎的特征:非胸膜炎性胸痛、咳嗽、肌肉酸痛和发热。胸片显示为段或叶实变伴有空气支气管造影征,偶有肺不张。单侧受累31例。胸腔积液9例,其中4例为血性。2例作诊断性肺血管造影均正常。14例作肺功能检查,其中4例缺氧,PO_2在75毫米汞柱以下,PCO_2则正常。肺活量与1秒钟用力肺活量(FEV_1)亦均正常。用红霉素及四环素治疗后临床及X线均有进步,5～14天内肺部浸润消失。本组中有4例系统性红斑狼疮,3例镰状细胞病,3例淋巴网细胞瘤。
The authors report 100 cases of mycoplasma pneumonia clinical and X-ray findings. The clinical manifestations of the disease may affect the upper lobe or lower lobe of the lung, single or bilateral, and may be associated with pleural effusion, chest X-ray showed consolidation or diffuse reticular nodular infiltration, the authors found There are two different clinical-X-ray syndromes: Group 1 48 patients with an average age of 26 years showed characteristics of acute pneumonia: non-pleuritic chest pain, cough, sore muscle and fever. Chest radiograph showed segment or leaf consolidation accompanied by air bronchogram signs, occasionally atelectasis. Unilateral involvement in 31 cases. Pleural effusion in 9 cases, of which 4 were bloody. 2 cases of diagnostic pulmonary angiography were normal. Fourteen patients underwent pulmonary function tests, of which 4 were hypoxic, PO 2 was below 75 mmHg and PCO 2 was normal. Vital capacity and forced expiratory volume in one second (FEV_1) were also normal. With erythromycin and tetracycline treatment of clinical and X-ray have improved, 5 to 14 days disappeared pulmonary infiltration. In this group, there are 4 cases of systemic lupus erythematosus, 3 cases of sickle cell disease, 3 cases of lymphoblastoma.
