Cardiothoracic imaging findings of Proteus syndrome.

Sci Rep 2021 Mar 22;11(1):6577. Epub 2021 Mar 22.

Cardiovascular and Pulmonary Branch, National Heart Lung and Blood Institute, National Institutes of Health, Building 10, Room B1D416, 10 Center Drive, Bethesda, MD, 20814, USA.

In this work, we sought to delineate the prevalence of cardiothoracic imaging findings of Proteus syndrome in a large cohort at our institution. Of 53 individuals with a confirmed diagnosis of Proteus syndrome at our institution from 10/2001 to 10/2019, 38 individuals (men, n = 23; average age = 24 years) underwent cardiothoracic imaging (routine chest CT, CT pulmonary angiography and/or cardiac MRI). All studies were retrospectively and independently reviewed by two fellowship-trained cardiothoracic readers. Read More

Incidental Diagnosis of Swyer-James-MacLeod Syndrome in a Military Pilot.

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

Recurrent Exacerbations of Chronic Obstructive Pulmonary Disease Reveal Swyer-James-MacLeod Syndrome in a 63-year-old Patient.

Cureus 2021 Jan 10;13(1):e12601. Epub 2021 Jan 10.

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

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

A Pulmonary Sequestered Segment with an Aberrant Pulmonary Arterial Supply: A Case of Unique Anomaly.

Korean J Radiol 2016 Mar-Apr;17(2):302-5. Epub 2016 Mar 2.

Department of Radiology, Eulji Hospital, Eulji University, Seoul 01830, Korea.

We presented a rare case of a 64-year-old man with a combined anomaly of the bronchus and pulmonary artery that was detected incidentally. Computed tomography showed a hyperlucent, aerated sequestered segment of the right lower lung with an independent ectopic bronchus, which had no connection to the other airway. The affected segment was supplied by its own aberrant pulmonary artery branch from the right pulmonary trunk. Read More

Lung volume reduction of pulmonary emphysema: the radiologist task.

Curr Opin Pulm Med 2016 Mar;22(2):179-86

Division of Radiology, Department of Surgical Sciences, University of Parma, Parma, Italy.

Purpose Of Review: Several lung volume reduction (LVR) techniques have been increasingly evaluated in patients with advanced pulmonary emphysema, especially in the last decade. Radiologist plays a pivotal role in the characterization of parenchymal damage and, thus, assessment of eligibility criteria. This review aims to discuss the most common LVR techniques, namely LVR surgery, endobronchial valves, and coils LVR, with emphasis on the role of computed tomography (CT). 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.
