Abstract
Swyer-James syndrome (SJS), in literature also reffered to as Swyer-James-MacLeod syndrome or simply MacLeod syndrome, is a rare pulmonary disease characterized by unilateral hemithorax lucency which appears as a result of postinfectious obliterative bronchiolitis in childhood. We present the case report of a young woman - an active athlete - with this syndrome and we document the importance of a regular intensive physical activity on the improvement of a general condition of an individual with a severe pulmonary impairment.
