[A case of idiopathic pulmonary alveolar proteinosis with multiple localized ground-glass opacities].
A 58-year-old Japanese female consulted our staff with multiple localized ground-glass opacities in chest CT. She underwent video assisted thoracoscopic surgery for diagnosis. Histopathologic finding from surgery specimen in one of ground-glass opacities revealed bronchioloalveolar carcinoma. Six months later, we performed second video assisted thoracoscopic surgery, and histopathologic finding of all other ground-glass opacities revealed pulmonary alveolar proteinosis. Serum anti GM-CSF antibody elevated, and she was diagnosed as having idiopathic pulmonary alveolar proteinosis. A case of idiopathic pulmonary alveolar proteinosis presenting multiple localized ground-glass opacities is rare. And, differentiating ground-glass opacities of pulmonary alveolar proteinosis and bronchioloalveolar carcinoma by chest CT is difficult.
