A RARE CASE OF MCLEOD SYNDROME DIAGNOSED IN AN ADULT

Swyer-James-McLeod Syndrome (SJMS) or unilateral hyperlucent lung syndrome is a rare entity associated with postinfectious bronchiolitis obliterans occuring in childhood. It is characterized by hypoplasia and or agenesis of the pulmonary arteries resulting in pulmonary parenchyma hypoperfusion, showing a characteristic radiological pattern, such as translucent or hyperlucent unilateral lung. Typically, this disorder is diagnosed in childhood after an evaluation for recurrent respiratory infections but sometimes patients who have have minor symptoms or are asymptomatic may miss their diagnosis until adulthood. Here we present a case with Mcleod syndrome found in the differential diagnosis workup for unilateral hyperlucent lung.
