Swyer-James syndrome: A cause of adult-onset dyspnea in a patient with adult polycystic kidney disease.

Respir Med Case Rep 2022 3;36:101569. Epub 2022 Jan 3.

University of Oklahoma Health and Sciences Center, Department of Pulmonary, Critical Care and Sleep Medicine, 800 Stanton L Young Boulevard, AAT 8400, Oklahoma City, OK, 73104, USA.

Swyer-James syndrome (SJS) is a rare lung condition characterized by abnormal lung growth secondary to childhood post-infectious bronchiolitis obliterans. Usually, one lung is affected more than the other leading to asymmetrical lungs with one lung being significantly smaller. The disease can lead to pulmonary obstructive airflow physiology, bronchiectasis, and fibrosis. Read More

Chronic lung allograft dysfunction phenotype and prognosis by machine learning CT analysis.

Eur Respir J 2021 Dec 23. Epub 2021 Dec 23.

Toronto Lung Transplant Program, Ajmera Transplant Centre, University Health Network, Toronto, ON, Canada.

Background: Chronic lung allograft dysfunction (CLAD) is the principal cause of graft failure in lung transplant recipients and prognosis depends on CLAD phenotype. We used machine learning computed tomography (CT) lung texture analysis tool at CLAD diagnosis for phenotyping and prognostication compared to radiologists' scoring.

Methods: This retrospective study included all adult first double-lung transplant patients (01/2010-12/2015) with CLAD (censored 12/2019) and inspiratory CT near CLAD diagnosis. Read More

Congenital lung lesions: a radiographic pattern approach.

Pediatr Radiol 2022 Apr 30;52(4):622-636. Epub 2021 Oct 30.

Division of Pediatric Radiology, Department of Radiology, NYU Grossman School of Medicine, 550 First Ave., New York, NY, 10016, USA.

Congenital lung malformations represent a spectrum of abnormalities that can overlap in imaging appearance and frequently coexist in the same child. Imaging diagnosis in the neonatal period can be challenging; however, the recognition of several archetypal radiographic patterns can aid in narrowing the differential diagnosis. Major radiographic archetypes include (1) hyperlucent lung, (2) pulmonary cysts, (3) focal opacity and (4) normal radiograph. Read More

Aerosp Med Hum Perform 2021 Apr;92(4):281-285

Swyer-James-MacLeod syndrome (SJMS) is a specific form of bronchiolitis obliterans that occurs rarely, but represents recognized sequelae of common pediatric respiratory illness, and presents as unilateral hyperlucency on chest imaging. This case study describes such an incidental radiographic finding identified during the assessment of chest wall discomfort in a military pilot. A 35-yr-old military pilot presented to his flight surgeon with vague intermittent chest discomfort. Read More

Pulmonology Department, Laiko General Hospital, Athens, GRC.

Swyer-James-Macleod syndrome is an infrequent clinical condition characterized by unilateral hyperlucent lung as a complication following infectious bronchiolitis obliterans, typically diagnosed during childhood. However, in some patients, the diagnosis may be confirmed in adulthood. The syndrome can be misdiagnosed with other lung disorders such as asthma, pulmonary embolism, and pneumothorax, leading to inappropriate management and worse outcome. Read More

Swyer-James-Macleod Syndrome: Case Report and Brief Literature Review.

S D Med 2019 Nov;72(11):518-520

Division of Pulmonary, Critical Care, Sleep and Allergy, University of Nebraska Medical Center, Omaha, Nebraska.

Swyer-James-Macleod syndrome is a rare radiologic entity with radiolucent lung fields which could include the entire lung, a lobe or a subsegment. The pathogenesis is unclear but is thought to be related to childhood pulmonary viral and non-viral infections with subsequent vascular and alveolar distortion. It usually presents incidentally in asymptomatic patients on imaging, but could present with recurrent pulmonary infections, shortness of breath, cough, hemoptysis or bronchiectasis. Read More

Lung Hyperlucency: A Clinical-Radiologic Algorithmic Approach to Diagnosis.

Chest 2020 01 26;157(1):119-141. Epub 2019 Jul 26.

Pulmonary, Critical Care & Sleep Medicine, Lenox Hill Hospital, New York, NY; Medicine and Radiology, Barbara and Donald Zuckerberg School of Medicine at Hofstra/Northwell, New York, NY. Electronic address:

Areas of diminished lung density are frequently identified both on routine chest radiographs and chest CT examinations. Colloquially referred to as hyperlucent foci of lung, a broad range of underlying pathophysiologic mechanisms and differential diagnoses account for these changes. Despite this, the spectrum of etiologies can be categorized into underlying parenchymal, airway, and vascular-related entities. Read More
