结节病的临床及CT扫描研究

Study of CT and Clinical Manifestation of Sarcoidosis

目的 :探讨CT在胸部结节病诊断和鉴别诊断中的应用价值。材料与方法 :分析 2 1例经临床和病理证实的结节病患者的资料。结果 :结节病患者女性多于男性 ,女性患者是男性的 2 5倍。结节病可发生于任何年龄 ,但半数以上见于 40～6 0岁年龄组。结节病的临床症状多数较轻 ,且不具有特征性。结节病的胸部淋巴结肿大具有特征性 :两侧肺门淋巴结呈对称性肿大 ;纵隔淋巴结肿大部位按ATS分组法 ,多位于 4R/L、 5、 7和 10R组 ;肿大的纵隔淋巴结多数不融合 ,境界较清晰。按肺部病变的情况 ,结节病可分为Ⅰ、Ⅱ、Ⅲ期。结论 :CT在结节病的诊断和鉴别诊断中具有重要价值 ,并能随访病情的变化 。

Purpose:To explore the diagnosis and differential diagnosis value of the sarcoidosis by CT.Materials and Methods:21 cases of sarcoidosis proved by clinical and pathology were analysed.Results:intrathoracic lymph nodes in patients with sarcoidosis have characteristics:1.It might be accompanied by enlarged hilar and/or mediastinal lymph nodes;2.Bilateral hilar lymph nodes are symmetrical enlargement;3.The interface between the enlarged lymph nodes are discrete and clear.Grouped according to the ATS nodal classification,most enlarged lymph nodes were in 4 R/L,5,7 and 10 R.According to the pulmonary findings,sarcoidosis were divided into stage Ⅰ,Ⅱ and Ⅲ.Conclusion:CT scanning is very important for the diagnosis and differential diannosis of the sarcoidosis.It is very helpful for us to select the effective treatment.
