肺淋巴管性癌病指肿瘤在肺淋巴管内生长。大多数淋巴管位于支气管肺泡丛内、小叶间隙和肺的胸膜下区域。病理、放射线和CT发现有可能反应出位于这些区域的病变。本文复习21例肺淋巴管癌病的CT表现,对CT和病理表现进行了对照,并阐述了解剖异常的性质。本组21例中,男13例,女8例,平均年龄59岁(28～79)岁。其中肿瘤原发于肺部12例、 Lung lymphangitic cancer refers to the growth of tumors in the lung lymphatic vessels. Most lymphatic vessels are located within the bronchial alveolar space, the leaflet space and the subpleural region of the lung. Pathology, radiation and CT findings may reflect the presence of lesions in these areas. This review of CT findings of 21 cases of pulmonary lymphangitic cancer, CT and pathological findings were compared, and described the nature of anatomic abnormalities. The group of 21 cases, 13 males and 8 females, with an average age of 59 years (28 to 79 years). Including tumor in the lungs in 12 cases,
