目的分析肺郎格汉斯细胞组织细胞增生症(PLCH)的CT表现.方法 11例患者均行CT平扫,其中8例加HRCT扫描.11例均经病理确诊为PLCH.结果 11例PLCH的主要CT表现为囊腔和结节.2例仅表现为囊腔,1例仅表现为结节且多数结节伴空洞;余8例为囊腔与结节影合并存在,其中4例以囊腔为主要表现,无一例以结节影为主,2例出现间质性改变.病变的分布:1例仅有囊腔且位于左上肺;10例上、中、下肺均可见,其中2例以下肺及肋膈角区明显;3例以上叶和下叶背段明显,中叶及舌叶病变相对较轻;8例肋膈角区相对较轻.结论 PLCH的CT表现有一定的规律和特征,熟悉这些表现,有助于对该病的早期诊断.

Objective To analyzes the CT manifestations of pulmonary Langerhans cell histiocytosis (PLCH). Methods CT features of 11 patients with PLCH proved pathologically were analyzed retrospectively. Results The main findings in 11 PLCHs were cysts and nodules. Two cases only had cysts,and 1 only had nodules, which most had cavitations. The other 8 cases showed cysts and nodules with 4 cases mainly manifested with cysts and nine mainly manifested with nodules. Two cases had pulmonary interstitial changes. One case only had cysts in the left upper lung field and 10 cases had lesions not only in the upper and middle but in the lower lung field, which 2 cases had more lesions in the lower and costophrenic angle field and 8 cases had less lesions in the costo-phrenic angle field. Three of these 8 cases had more lesions in the superior lobe and apical segment of lower lobe. Conclusion CT manifestations of PLCH are helpful for the early diagnosis.
