目的通过分析成人气管支气管异物的临床及CT表现,探讨成人气管支气管异物的临床及CT影像特点。方法回顾性分析经过硬支气管镜钳取证实或手术证实的18例成人气管支气管异物患者的临床及CT影像资料,分成急性组和慢性组,对比分析其临床症状、异物性质及位置、CT表现。结果成人气管支气管异物18例,急性组6例,慢性组12例,有明确异物吸入史者7例,CT直接显示异物者10例,发现肺叶或肺段炎症11例,肺不张4例。结论急性成人气管支气管异物患者多数病史明确,CT容易正确诊断;慢性成人气管支气管异物患者由于无明确病史,症状无特异性,容易误诊为肺炎、肺部肿瘤等其它疾病。
Objective To analyze the clinical and CT features of adult tracheal and bronchial foreign bodies by analyzing the clinical and CT findings of adult tracheal and bronchial foreign bodies. Methods The clinical and CT images of 18 adult patients with tracheobronchial foreign bodies confirmed by the bronchoscope forceps or confirmed by surgery were retrospectively analyzed. The clinical symptoms, foreign body features, location and CT findings were compared between the acute group and the chronic group. Results There were 18 cases of tracheobronchial foreign bodies in adults, 6 cases of acute group and 12 cases of chronic bronchitis. Among them, 7 cases had clear history of foreign body aspiration, 10 cases showed foreign body directly by CT, 11 cases of lobular or pulmonary section inflammation and 4 cases of atelectasis. Conclusion Most patients with acute adult tracheobronchial foreign body have definite history and CT is easy to diagnose correctly. Patients with chronic adult tracheal and bronchial foreign body are easily misdiagnosed as other diseases such as pneumonia and lung tumor because they have no definite history and no specific symptoms.
