Pulmonary air meniscus sign

Respiration. 1984;46(1):139-44. doi: 10.1159/000194682.


In chest roentgenograms, the pulmonary meniscus sign is a crescent-shaped inclusion of air surrounded by consolidated lung tissue. The common cause is aspergilloma. A hydatid cyst is, however, the most common cause in endemic areas. In this study, 10 cases with meniscus sign are presented and the pertinent literature is reviewed.
