老年前期及老年人胸部结节病的CT表现

目的：总结老年前期及老年胸部结节病患者的CT表现。方法：回顾性分析25例确诊的老年前期及老年胸部结节病患者的CT图像。结果：9例CT呈典型表现，16例CT呈不典型表现，其中纵隔和一侧肺门淋巴结肿大者3例（3／25），无肺门淋巴结肿大的单纯纵隔淋巴结肿在者7例（7／25），无纵隔淋巴结肿大的单侧肺门淋巴肿大者1例（1／25），仅有肺部改变而无胸部淋巴结肿大者5例（5／25）。后者在首诊时全部误诊。结论：老年人胸部结节病的CT表现多不典型，认识此种表现在诊断中很重要。

CT features of thoracic sarcoidosis in senile and pre-senile patients

Objective To study the CT features of thoracic sarcoidosis in senile and pre senile patients. Methods The findings in 25 patients(14 elderly patients and 11 pre senile patients) manifesting thoracic sarcoidosis were reviewed. Results Nine patients with typical findings and sixteen patients with atypical findings were reported at retrospective presentation. The atypical patterns at CT included mediastinal adenopathy with unilateral hilar adenopathy( n =3, 3/25), mediastinal adenopathy alone ( n =7, 7/25), unilateral hilar adenopathy alone ( n =1, 1/25), and lung abnormal findings without any mediastinal and/or hilar adenopathy ( n =5, 5/25). The latter 5 patients were misdiagnosed at the first clinical consultation. Conclusions The thoracic sarcoidosis in the elderly often manifests atypical patterns, and the recognition of the key point is of importance and helpful for the definite diagnosis.
