Eighteen patients with pulmonary lesions of histiocytosis X were studied with high-resolution computed tomography (CT). Thin-walled cysts were found in all but one patient. The other abnormalities included nodules (n = 14), cavitated nodules (n = 3), thick-walled cysts (n = 7), reticulation (n = 4), ground-glass opacities (n = 4), and irregular interfaces (n = 4). The lesions were most often diffuse (n = 16), with a topographic predominance in the upper or middle lung zones in nine patients. Comparison of CT scans and chest radiographs shows that small and large cysts and micronodules are better detected with CT. Comparison of abnormalities found in patients in the early and late stages of the disease, as well as the evolution observed in one case, suggests that CT patterns progress from nodules to cavitated nodules and thick-walled cysts to cysts to confluent cysts.
对18例肺组织细胞增多症X患者进行了高分辨率计算机断层扫描（CT）研究。除1例患者外，其余患者均发现薄壁囊肿。其他异常包括结节（n = 14）、空洞结节（n = 3）、厚壁囊肿（n = 7）、网状影（n = 4）、磨玻璃影（n = 4）和不规则界面（n = 4）。病变最常见为弥漫性（n = 16），9例患者在上肺或中肺区有地形优势。CT扫描与胸部X线片的比较表明，CT能更好地检测出大小囊肿和微结节。对疾病早期和晚期患者发现的异常以及1例患者观察到的演变进行比较，提示CT表现从结节发展为空洞结节、厚壁囊肿发展为囊肿、融合囊肿。
