We report a case of pulmonary lymphangiomyomatosis in a young female. CT--and especially high resolution CT--is more specific and sensitive than chest radiography in showing the lung abnormalities. Pathognomonic CT findings are the presence of thin walled cystic air spaces spread throughout the lung parenchyma without nodules and without regional predominance and mostly surrounded by normal parenchyma. The superposition of the multiple thin walls of the cysts is responsible for the reticular interstitial pattern observed at chest radiography.
我们报告一例年轻女性的肺淋巴管平滑肌瘤病。在显示肺部异常方面，CT（尤其是高分辨率CT）比胸部X线摄影更具特异性和敏感性。CT的特征性表现是薄壁囊状气腔遍布肺实质，无结节，无区域优势，且大多被正常实质包围。囊肿的多个薄壁叠加形成了胸部X线摄影中观察到的网状间质影像。
