To analyze the computed tomography (CT) findings of lymphocytic interstitial pneumonia (LIP).
We retrospectively reviewed the clinical and CT findings of 36 patients with LIP, including 25 women and 11 men, with a mean age of 52.5 years (age range, 22-78 years).
The main associated diseases with LIP were Sjögren syndrome (42%), human immunodeficiency virus infection (17%), amyloidosis (17%), Sjögren syndrome associated with secondary amyloidosis (11%), idiopathic (8%), and systemic lupus erythematosus (5%). The predominant CT abnormalities were multiple cystic airspaces (n = 35), small nodules (n = 15), ground-glass opacities (n = 13), bronchiectasis and/or bronchiolectasis (n = 8), and thickening of the bronchovascular bundles (n = 8). Other CT findings included reticular opacities (n = 7), calcified nodules (n = 4), airspace consolidation (n = 4), emphysema (n = 3), honeycombing (n = 3), lymph node enlargement (n = 2), mosaic attenuation pattern (n = 1), and cavitated nodules (n = 1).
The main CT findings of LIP were multiple cysts, small nodules, and ground-glass opacities.
分析淋巴细胞间质性肺炎（LIP）的计算机断层扫描（CT）表现。
我们回顾性分析了36例LIP患者的临床和CT表现，其中女性25例，男性11例，平均年龄52.5岁（年龄范围22 - 78岁）。
与LIP相关的主要疾病有干燥综合征（42%）、人类免疫缺陷病毒感染（17%）、淀粉样变性（17%）、干燥综合征合并继发性淀粉样变性（11%）、特发性（8%）和系统性红斑狼疮（5%）。主要的CT异常表现为多发囊状气腔（n = 35）、小结节（n = 15）、磨玻璃影（n = 13）、支气管扩张和/或细支气管扩张（n = 8）以及支气管血管束增粗（n = 8）。其他CT表现包括网状影（n = 7）、钙化结节（n = 4）、实变影（n = 4）、肺气肿（n = 3）、蜂窝状改变（n = 3）、淋巴结肿大（n = 2）、马赛克样衰减（n = 1）和空洞性结节（n = 1）。
LIP的主要CT表现为多发囊肿、小结节和磨玻璃影。
