Radiograph and CT study of a 10-year old boy with Swyer-James-MacLeod syndrome and post mycoplasma infection at the age of 2 years. The radiograph reveals hyperlucency of the right lung without any significant increase in volume. The CT study confirms the markedly hyperlucent parenchyma of the right lung. In addition, the vascular tree is rarefied and cylindrical bronchiectasis are evident in the affected areas.
CT study of a 9-year old girl with Swyer-James-MacLeod syndrome. There are markedly hyperlucent lung areas, e.g. in the left lower lobe, here with bronchiectasis and markedly rarefied vasculature (d). The functionless left lower lobe is clearly contracted and atelectatic (a, c), in this case left hemithorax is reduced in volume and has a slight mediastinal shift.
