A 57-year-old woman was admitted to our hospital because of a slowly growing pulmonary tumor with a 34 year history. Chest roentgenogram on admission showed a 42 mm sharply demarcated solitary tumor in the left upper lobe. Chest CT revealed a slit-like pulmonary air meniscus. Left upper lobectomy was performed. A specimen from the resected lung histologically showed solid, papillary and hemorrhagic patterns, and the diagnosis of pulmonary sclerosing hemangioma was therefore made. Pulmonary air meniscus sign in pulmonary sclerosing hemangioma is rare. We think one possible mechanism in the production of an air meniscus sign in sclerosing hemangioma is bleeding in communication with a bronchus.
一名57岁女性因肺部肿瘤生长缓慢且有34年病史而入住我院。入院时胸部X线片显示左上叶有一个42毫米边界清晰的孤立性肿瘤。胸部CT显示有裂隙状肺空气半月征。行左上叶切除术。切除肺组织的标本组织学显示为实性、乳头状和出血性模式，因此诊断为肺硬化性血管瘤。肺硬化性血管瘤中的肺空气半月征罕见。我们认为硬化性血管瘤中产生空气半月征的一种可能机制是与支气管相通处出血。
