Abstract:
Swyer-James-MacLeod syndrome is a rare pulmonary disorder that is characterized radiologically by pulmonary lobar or multilobar hyperlucency produced by decreased pulmonary vascularization usually due to a previous infectious process. It is frequently a casual finding in recurrent pulmonary infections or in the study of asthma symptoms. We present the case of a 6-year-old patient who was diagnosed with Swyer-James-MacLeod syndrome after a persistent pneumoniae. A multidisciplinary approach was conducted, with a satisfactory progress up to date, combining medical treatment with respiratory physiotherapy.
Insights
Swyer-James-MacLeod syndrome, a rare lung disorder, presents as hyperlucency due to reduced vascularization, often from infection. This case highlights successful multidisciplinary management in a child with persistent pneumonia.
Area of Science:
- Pediatric Pulmonology
- Radiology
- Infectious Diseases
Background:
- Swyer-James-MacLeod syndrome is a rare pulmonary condition.
- Characterized by lobar hyperlucency and decreased pulmonary vascularization.
- Often results from prior infectious processes.
Observation:
- A 6-year-old patient presented with persistent pneumonia.
- Diagnosis of Swyer-James-MacLeod syndrome was established.
- The condition was identified as a likely incidental finding during pneumonia workup.
Findings:
- Radiological evidence of unilateral hyperlucency consistent with Swyer-James-MacLeod syndrome.
- Confirmed decreased pulmonary vascularization in the affected lobe.
- Underlying cause attributed to a previous infectious event.
Implications:
- Demonstrates the importance of considering Swyer-James-MacLeod syndrome in pediatric cases of persistent pneumonia.
- Highlights the efficacy of a multidisciplinary approach combining medical and physiotherapy treatments.
- Suggests that early diagnosis and tailored management can lead to satisfactory patient outcomes.
