Hyperlucent lung; Pulmon hiperlucente

Abstract

Unilateral hyperlucent lung is also known as Swyer-James Syndrome, Macleod Syndrome or lobular or unilateral emphysema. It is an uncommon disease characterized by lung or unilateral lobe hiperlucency associated to an air trapping upon expiration. As regards to etiology, 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 effort 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 in an asymptomatic person. 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, it is presented the clinical case of a patient who had a parainfluenza 3 bronchopneumonia when he was a month and eighteen days of age. The differential diagnosis of this syndrome should be done with other thoracic entities that diminish the radiological pulmonary unilateral  More>>

(author) [Spanish] El pulmon hiperlucente unilateral tambien se ha denominado Sindrome de Swyer-James, Sindrome 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 aereo en la espiracion. En cuanto a la etiologia, existe evidencia que se atribuye a una enfermedad adquirida que aparece tras una infeccion pulmonar durante la infancia, probablemente una bronquiolitis o una neumonia viral. El cuadro clinico es variable: algunos pacientes se encuentran asintomaticos, otros con infecciones de vias respiratorias bajas a repeticion, desde los primeros anos de vida y los que presentan disnea de esfuerzo. El diagnostico se suele realizar como un hallazgo incidental al hacer una radiografia de torax a un nino por infecciones respiratorias repetidas, o en la edad adulta en una exploracion radiologica de rutina, en una persona por lo demas asintomatica. Es importante diferenciar este sindrome de otras causas de hiperclaridad pulmonar unilateral en las radiografias de torax convencionales. Pocos casos del Sindrome Swyer-James han sido reportados en ninos. Se presenta el caso clinico de un paciente quien tuvo una bronconeomonia parainfluenza 3 al mes y 18 dias de edad. El diagnostico diferencial de este sindrome se debe hacer con otras entidades toracicas que disminuyen la densidad radiologica pulmonar unilateral. Se describe el caso clinico de un nino que es portador de pulmon hiperlucente. (autor)}
