Unilateral lung hyperlucency in an adult: an unusual cause


We report a case of young adult with unilateral lung hyperlucency. His radiological features were suggestive of Swyer–James syndrome. The condition is uncommon in adults. We report this rare case with discussion on clinical presentation, diagnosis, and management of Swyer–James syndrome. The report also throws light on various other causes of unilateral lung hyperlucency and its approach.
