A Case of Unilateral Hyperlucency of the Lung: a Rare Adult Occurrence of Swyer-James-MacLeod Syndrome.

Maedica (Buchar) 2018 Jun;13(2):143-146

"Grigore T. Popa" University of Medicine and Pharmacy, Iasi, Romania.

Swyer-James-MacLeod syndrome is a rare pulmonary disorder that exhibits unilateral hyperlucency of a part of or the entire lung and because it is usually asimptomatic the diagnostic of this illness is discovered accidentally after a chest X-ray. Although the cause of this disorder is not completely understood, most authors believe that this is due to late sequela of infectious bronchiolitis that occurs during childhood. The symptoms presented by the individuals are often scarce at the moment of diagnostic, but a history of recurrent episodes of pulmonary infection accompanied by dyspnea, hemoptysis and/or chronic productive cough should raise the suspicion for such a diagnosis.

Service de pneumologie, hôpital Pasteur, universite Côte-d'Azur, FHU OncoAge, centre hospitalier universitaire de Nice, 06000 Nice, France.

Introduction: Chronic obstructive pulmonary disease (COPD) is a common condition that may initially look simple but may conceal other diseases capable of accelerating its natural history or even simulating it. We describe four cases presenting as COPD with emphysema that were reclassified on the basis of certain clinical characteristics and the radiological pattern.

Case Reports: A 52 year old never smoking woman presenting with emphysema was eventually diagnosed as having lymphangioleiomyomatosis on the basis of an abdominal CT scan showing kidney angiomyolipomas. Read More

Swyer-James-MacLeod syndrome-a rare diagnosis presented through two adult patients.

Respirol Case Rep 2017 09 16;5(5):e00245. Epub 2017 Jun 16.

Department of Pulmonary Medicine King George Medical University Lucknow India.

Swyer-James-MacLeod syndrome (SJMS) is a rare syndrome of acute obliterative bronchiolitis following an early childhood infective insult to the lungs. This causes arrest of alveolarization, affecting lung development with hypoplasia of the ipsilateral pulmonary artery and results in a characteristic radiological pattern, such as a unilateral hyperlucent lung with expiratory air-trapping and pruned-tree appearance on pulmonary angiogram. The clinical presentation is either recurrent chest infections, exertional dyspnoea or it may be an incidental finding. Read More

Department of Radiology, Lancashire Teaching Hospitals NHS Foundation Trust, Royal Preston Hospital, Preston, UK.

Swyer-James-MacLeod syndrome is a rare, complex disease characterized by the radiological finding of unilateral hyperlucent lung due to pulmonary oligaemia and alveolar hyperdistention as a consequence of previous obliterative bronchiolitis (bronchiolitis obliterans). Idiopathic pulmonary fibrosis is a chronic, progressive, fibrosing interstitial pneumonia of unknown cause characterized by bilateral, chronic, progressive and irreversible fibrosis limited to the lungs. We report an interesting case of Swyer-James-MacLeod syndrome affecting one lung and Idiopathic pulmonary fibrosis affecting the contralateral lung. Read More

Swyer-James-Macleod syndrome mimicking an acute pulmonary embolism: a report of six adult cases and a retrospective analysis.

Clin Respir J 2018 Feb 1;12(2):404-409. Epub 2016 Aug 1.

Deparment of Chest Diseases, Faculty of Medicine, Ordu University, Ordu, Turkey.

Background And Aim: In patients with pulmonary embolism (PE), a pulmonary radiograph may reveal oligemic fields (the Westermark sign) associated with sites of occlusion of the pulmonary arteries, interruption or loss of the artery line (the knuckle sign), and even unilateral hyperlucency attributable to reduced overall lung vascularity. In Swyer-James-Macleod syndrome (SJMS), which develops as a result of bronchiolitis obliterans, unilateral hyperlucency is evident because of emphysema and hypoplasia of the pulmonary artery and its branches. Therefore, SJMS cases with clinical and laboratory data compatible with PE may in fact be confused with PE. Read More

Allergic bronchopulmonary aspergillosis complicating Swyer-James-Macleod's syndrome: case report and review of literature.

Department of Pulmonary Medicine, Postgraduate Institute of Medical Education and Research, Chandigarh, India. mail: Phone: +91 172 275 6825 Fax: +91 172 274 8215.

Allergic bronchopulmonary aspergillosis (ABPA) is a pulmonary disorder that results from immune responses mounted against antigens of Aspergillus fumigatus, resulting in non-specific respiratory symptoms and structural lung damage. Classically defined in individuals suffering from bronchial asthma and cystic fibrosis, ABPA has recently been described in other lung diseases including COPD, pulmonary tuberculosis, idiopathic bronchiectasis and others. Herein, we report the first case of ABPA complicating Swyer-James-Macleod's syndrome that was successfully treated with oral antifungal therapy. Read More

Areas with reduced density are a common finding with thin-slice computed tomography (CT) examinations of lung parenchyma. Diffuse and localized patterns can be differentiated. The most frequent cause for a diffuse decrease in density is pulmonary emphysema which can be classified into centrilobular, panlobular and paraseptal emphysema based on the distinct anatomical features.
