摘要
目的分析64层螺旋CT肺部结节病的影像学表现,特别是结节病CT强化后的特征性表现,以提高对本病的认识和诊断水平。方法回顾性分析经病理证实及临床治疗符合诊断标准的21例肺部结节病的CT表现。结果 21例结节病中,肺门、纵隔淋巴结肿大20例,肺内病变18例,其中沿支气管血管束分布及胸膜下肺结节13例,5例有磨玻璃影。结论双肺门对称性淋巴结增大、纵隔淋巴结增大以及沿支气管血管束分布的结节影为结节病的特征性表现。需与胸内恶性淋巴瘤、结核及胸部转移瘤的鉴别,可以从纵隔淋巴结的好发部位,强化方式等方面进行鉴别;另外结节病对激素治疗有效。
Objective To analyze CT features in 64-slice spiral of chest sarcoidosis ,especially enhanced scan, so as to improve CT diagnostic accuracy. Methods CT features of 21 chest sarcoidosis cases proven by clinicl therapy and pathology were retrospectively analyzed. Results Of 21 cases, 20 cases presented mediastinal lymph node enlargement and hilar lymph node enlargement, 18 cases presented pulmonary parenchymal abnormality, 13 cases presented the nodules of pulmonary which mostly distributed around the bronchovascular bundle, and 5 cases presented ground glass opacity. Conclusion The imaging finding of hilarl and mediasina lymph node enlargement and nodes distributing along bronchi and vascular bundle is arecharacteristic sign of intrathoracic sarcoidosis. Srcoidosis could be diagnosted by the location,mode and degree of enhancement in mediastinal lymph node. Besides, Sarcoidosis is useful after hormonal therapy.
