%X El pulm車n hiperlucente unilateral tambi谷n se ha denominado s赤ndrome de Swyer-James, s赤ndrome de Macleod o enfisema lobular o unilateral. Es una enfermedad poco frecuente que se caracteriza por una hiperclaridad pulmonar o lobar unilateral asociada a un atrapamiento a谷reo en la espiraci車n. En cuanto a la etiolog赤a, existe evidencia que se atribuye a una enfermedad adquirida que aparece tras una infecci車n pulmonar durante la infancia, probablemente una bronquiolitis una neumon赤a viral. El cuadro cl赤nico es variable: algunos pacientes se encuentran asintom芍ticos, otros con infecciones de v赤as respiratorias bajas a repetici車n, y los que presentan disnea de esfuerzo. El diagn車stico se suele realizar como un hallazgo incidental al hacer una radiograf赤a de t車rax a un ni o por infecciones respiratorias repetidas, o en la edad adulta en una exploraci車n radiol車gica de rutina, en una persona por lo dem芍s asintom芍tica. El diagn車stico diferencial de este s赤ndrome se debe hacer con otras entidades tor芍cicas que disminuyen la densidad radiol車gica pulmonar unilateral. A continuaci車n se describe el caso cl赤nico de un ni o que es portador de pulm車n hiperlucente. Unilateral hiperlucent lung is also known as Swyer-James Syndrome, Macleod Syndrome, lobular or unilateral emphysema. It is an uncommon disease characterized by hiperlucency of one lobe or lung and air trapping upon expiration. This syndrome is considered to be an acquired disease that appears secondary to respiratory infections during the early years of life, probably bronchiolitis and/ or viral pneumonia. The clinical presentation varies among patients. Some of them are asymptomatic, others present a history of recurrent episodes of pulmonary infections from early years of life or present exertional dyspnea. The diagnosis is usually made accidentally by a chest radiograph in a child with history of respiratory infections or in an adult during a routine chest x- ray. It is important to differentiate this syndrome from other causes of unilateral pulmonary hiperlucency on conventional chest x-rays. Few cases of Swyer-James Syndrome in children have been reported, we present herein the clinical case of a patient who had a Para influenza 3 bronchopneumonia when he was a month and eighteen days of age. The ensuring chest radiographs showed a hiperlucent lung. Further testing confirmed the clinical diagnosis of an unilateral hiperlucent lung.
