This article will illustrate and describe the spectrum of diseases associated with air cysts at high-resolution CT (HRCT).
HRCT is an important modality in the evaluation of interstitial lung disease to include cystic lung disease. Although most commonly associated with lymphangioleiomyomatosis or Langerhans cell histiocytosis, cystic lung disease is increasingly being recognized as a feature of other entities. Awareness of the spectrum of HRCT findings associated with these diseases may help the trained observer narrow the differential diagnosis.
本文将阐述并描述高分辨率 CT（HRCT）下与空气囊肿相关的疾病谱。
HRCT 是评估间质性肺疾病（包括囊性肺疾病）的重要方式。虽然最常与淋巴管肌瘤病或朗格汉斯细胞组织细胞增生症相关，但囊性肺疾病越来越被认为是其他疾病的特征之一。了解这些疾病相关的 HRCT 表现谱，可能有助于训练有素的观察者缩小鉴别诊断范围。
