lung was observed in early stages of FBA, while atelectasis or consolidation indicated a fairly advanced stage.
The chest radiograph of patients with UAPA typically shows asymmetric lung fields, with an ipsilateral small hemithorax holding a hyperlucent
Chest radiograph showed hyperlucent
lungs with atelectatic bands in both lower zones and blunting of the right costophrenic angle.
Presented in sections on the chest wall, pleura, and mediastinum; pulmonary opacities; and hyperlucent
abnormalities, the images include pleural effusions, anterior mediastinal mass, segmental and lobar opacities, multiple nodules and masses, and hyperlucent
Chest radiographic signs include a unilateral hyperlucent
lung field with collapse of the lung, tracheal deviation and mediastinal displacement (see Figure 4) (Ho & Gutierrez 2009).
Chest radiograph (Figure 1) showed hyperlucent
right lung with decreased vascular markings and a small hilar shadow.
Because of the decreased parenchymal perfusion, this syndrome is often mentioned as translucent or hyperlucent
Swyer-James syndrome (unilateral hyperlucent
lung) in children.
In 1953, Swyer and James (1) described unilateral, hyperlucent
lung syndrome in a 6-year-old boy.
Ad7 infections have also been associated with diseases of the central nervous system (8,9) and long-term respiratory sequelae that include bronchiectasis and hyperlucent
lung or McLeod syndrome (10).
Swyer James syndrome is an uncommon abnormality characterized radiologically by hyperlucent
lobe or lung and functionally by air trapping during expiration.
On CT, the bronchovascular tissue in this region is proportionally less than in the remainder of the lungs, and some of the left lung vessels were shown to be convex anteriorly (white arrows) indicating increasing volume of the hyperlucent
region when compared to the prior CT (Figure 4).
