目的:分析胸部结节病的影像学表现,探讨造成结节病初诊困难的原因。方法:分析57例胸部结节病临床资料及影像学表现。其中有32例初诊为其他疾病,但需进一步检查除外结节病。结果:57例均可见胸部淋巴结增大,其中42例纵隔、双侧肺门淋巴结均增大;8例纵隔、单侧淋巴结增大;7例仅见纵隔淋巴结增大。36例出现肺部病变;4例胸膜病变。结论:结节病的胸部影像及临床表现缺乏特异性,肺部病变及不典型胸部淋巴结增大是导致结节病初诊困难的主要原因。
OBJECTIVE: To analyze the imaging findings of the thoracic sarcoidosis and to explore the causes of the first diagnosis of sarcoidosis. Methods: 57 cases of chest sarcoidosis clinical data and imaging findings. Among them, 32 cases were newly diagnosed as other diseases except for further sarcoidosis. Results: All of the 57 cases showed increased thoracic lymph nodes, including 42 cases of mediastinal and bilateral hilar lymph nodes, 8 cases of mediastinal and unilateral lymph nodes, and 7 cases of mediastinal lymph nodes. 36 cases of lung disease; 4 cases of pleural disease. Conclusion: The stenosis of the chest imaging and clinical manifestations of the lack of specificity, pulmonary lesions and atypical chest lymph nodes is the leading cause of first diagnosis of sarcoidosis difficult.
