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

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

Swyer-James-MacLeod Syndrome (SJMS) is an uncommon, emphysematous disease characterized by obliteration of the small bronchioles, hypoplasia/or absence of pulmonary artery and peripheral vascular bed. It is most commonly diagnosed in childhood. Patients are often asymptomatic or they could suffer from symptoms of recurrent pulmonary infections. Read More

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 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

This case describes a female patient who presented with an acute on chronic deterioration in respiratory symptoms, on a background of chronic obstructive pulmonary disease and heavy cigarette smoking. Chest radiograph demonstrated long-standing hyperlucency of the right lower lobe, with further imaging later confirming the rare combination of Swyer-James-MacLeod syndrome and multiple pulmonary arteriovenous malformations within the affected lung.

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

A 24-year-old female with a history of Swyer-James-MacLeod syndrome presented with acute onset of pleuritic chest pain and was initially diagnosed with acute pericarditis. The 12-lead electrocardiogram demonstrated typical diffuse ST-segment elevation and PR-segment depression. Symptoms resolved rapidly with anti-inflammatory therapy consisting of ibuprofen and colchicine. Read More

Unilateral hyperlucent lung was firstly described by Swyer and James 1950s. After that, some patients with same disease were detected by Macleod . Then this syndrome was named as Swyer- James-Macleod syndrome (SJMS), and this syndrome includes a smaller or normal sized unilateral hyperlucent lung. Read More

Swyer-James-MacLeod syndrome (SJMS) is an uncommon obliterative lung disease that is radiologically characterized by hyperlucency of a part of or the entire lung. A 33-year-old man presented to our hospital for chest tightness. A chest X-ray revealed unilateral hyperlucency of left lower lung, and contrast-enhanced computed tomography (CT) of the chest disclosed a hyperlucent left lung without vascularity. Read More

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

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

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

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.
