Ground glass opacities with peribronchovascular distribution is noted at middle and upper zones of the both lung parenchyma. Traction bronchiectasis with fibrotic changes are seen particularly at left upper lobe. There are calcified geranoloma at left upper lobe and several peripheral nodules at right upper lobe . Right parateraceal lymphadenopathy is noted.
In this case the appearance resembles a ground glass attenuation, but with a close look you may appreciate that the increased attenuation is the result of many tiny grouped nodules. The findings are consistent with sarcoidosis ; Pattern and distribution of ground glass opacities is compatible with alveolar type of sarcoidosis.
