The Swyer - James syndrome ( SJMS, Syn Swyer - James - Macleod syndrome); by George CW James, Paul Robert Swyer, William Mathieson Macleod, who had in 1953 and 1954, the clinical picture described is the syndrome of unilateral lung bright in X-ray image. The Swyer - James syndrome is a rare variant of a post-infectious bronchiolitis obliterans. It is one of the chronic obstructive pulmonary disease. Here there is a hypoplasia of the pulmonary vasculature, including their early childhood. The reason for early childhood pneumonia is assumed. SJMS is an incurable respiratory disease with reduced pulmonary function. The symptoms are similar to those of chronic obstructive bronchitis, or cystic fibrosis
In conventional X-ray image unilaterally increased radiolucency and vascular poverty falls on the affected side. The findings are also detectable in the cross-sectional imaging such as MRI or CT.
The disease begins as obliterative bronchiolitis with associated vasculitis, often after infection by adenovirus, measles or pertussis.
