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

Complication of post-infectious bronchiolitis obliterans (Swyer-James syndrome).

Rev Assoc Med Bras (1992) 2015 Sep-Oct;61(5):404-6

Medical Department, Faculdade São Lucas, Porto Velho, RO, Brazil.

Swyer-James syndrome is a complication of post-infectious bronchiolitis obliterans that causes inflammation and fibrosis of the bronchial walls. There are two types: asymptomatic, with most cases diagnosed in adults during routine radiological examinations; and symptomatic, most commonly found in children. Here, we report the case of a 6-year-old child with recurrent dyspnea since the age of 3, who showed signs and symptoms of bronchiolitis obliterans and radiological signs of bronchial wall thickening and air trapping.

Division of Cardiothoracic Imaging, Department of Medical Imaging, University of Toronto, NCSB-IC560, 585 University Avenue, M5G2N2, Toronto, ON, Kanada.

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.

Department of Radiology, Section of Pediatric Radiology, C. S. Mott Children's Hospital, University of Michigan Health System, 1500 E Medical Center Dr, Ann Arbor, Mich 48109, USA.

Unilateral hyperlucent hemithorax is a common pediatric chest radiographic finding that may also be seen at computed tomography. It may result from congenital or acquired conditions involving the pulmonary parenchyma, airway, pulmonary vasculature, pleural space, and chest wall, as well as from technical factors such as patient rotation. Unilateral hyperlucent hemithorax has a broad differential diagnosis that includes unilateral emphysematous or bullous disease, pneumatocele, foreign body aspiration, Swyer-James syndrome, congenital lobar emphysema, endobronchial mass, unilateral pulmonary agenesis, proximal interruption of the pulmonary artery, scimitar syndrome, diaphragmatic hernia, and Poland syndrome.

Imaging diagnosis--Congenital lobar emphysema in a dog.

Vet Radiol Ultrasound 2011 Jan-Feb;52(1):79-81

Section of Diagnostic Imaging, Louisiana State University, School of Veterinary Medicine, Baton Rouge, LA 70803, USA.

A 14-week-old female West Highland White Terrier developed acute dyspnea. Radiographically there was an enlarged, hyperlucent caudal portion of the left cranial lung lobe and a diffuse, severe interstitial-to-alveolar pattern in the remaining lung lobes that was accentuated caudodorsally. Computed tomography confirmed the presence of the emphysematous lobe and further showed it to have focal lobar bronchial collapse. Read More

Collateral ventilation to congenital hyperlucent lung lesions assessed on xenon-enhanced dynamic dual-energy CT: an initial experience.

Korean J Radiol 2011 Jan-Feb;12(1):25-33. Epub 2011 Jan 3.

Department of Radiology and Research Institute of Radiology, Asan Medical Center, University of Ulsan College of Medicine, Seoul 138-736, Korea.

Objective: We wanted to evaluate the resistance to collateral ventilation in congenital hyperlucent lung lesions and to correlate that with the anatomic findings on xenon-enhanced dynamic dual-energy CT.

Materials And Methods: Xenon-enhanced dynamic dual-energy CT was successfully and safely performed in eight children (median age: 5.5 years, 4 boys and 4 girls) with congenital hyperlucent lung lesions. Read More

Swyer-James-MacLeod syndrome with ipsilateral herniation of hyperinflated hyperlucent lung.

BMJ Case Rep 2011 Aug 31;2011. Epub 2011 Aug 31.

Department of Pulmonary Medicine, Chhatrapati Shahuji Maharaj Medical University, Lucknow, Uttar Pradesh, India.

Swyer-James-MacLeod syndrome is characterised by unilateral hyperlucency on chest radiograph with small or normal-sized lung on the affected side and compensatory hyperinflation of opposite lung. Hyperinflation of the affected lung is a very rarely reported entity. An adult female patient, who presented with exertional breathlessness and diagnosed to have hypoplastic left pulmonary artery with hyperlucent, hyperinflated and herniated left lung is described.
