We report a case of 33 year old man who consulted us in 1994 for recurrent bronchitis sometimes with haemoptysis. The physical examination was unremarkable. At consultation abnormal fascicular sounds were noted at the left base. A chest x-ray showed hyperlucency of the left lung associated with a very small ...

We report an unusual case of patent ductus arteriosus (PDA) co-existing with bronchial carcinoid. The initial radiographic presentation was hyperlucent lung. Causes and possible mechanisms of unilateral hypoperfusion of the lung are reviewed briefly. Useful diagnostic modalities in evaluating a hyperlucent lung are also discussed.

A 39-yr-old woman developed progressive exertional dyspnea 13 yr after receiving mediastinal irradiation for Hodgkin's disease. Chest roentgenogram showed a hyperlucent right lung. Pulmonary blood flow was markedly reduced on the right by ventilation-perfusion scanning. Pulmonary angiography showed attenuation and diffuse atrophy of the right pulmonary artery and its branches. ...

Emphysematous bullae isolated on a healthy lung and primitive progressive dystrophic emphysema all belong to the dystrophic hyperlucent lung and are surgical cases. Having recalled the excellent prognosis of isolated bullae, the authors analyzed the surgical indications in the progressive dystrophic emphysema concerning 66 observations of which 52 cases were ...

At 23 months of age, one of a pair of monozygotic twins with radiographic unilateral hyperlucent lung was evaluated by radionuclide ventilation/perfusion pulmonary studies, which revealed a ventilation/perfusion mismatch of an entire lung. This twin died, and autopsy revealed pulmonary arterial thrombosis and histological changes compatible with homocystinuria, which was ...

Unilateral emphysema secondary to bronchial obstruction by a foregut-derived mediastinal cyst is rare. Here we describe an infant with a unilateral hyperlucent lung due to compression on the left main bronchus by an esophageal cyst, visualized by chest computed tomography and magnetic resonance imaging. A chest roentgenogram and a perfusion ...

11 cases of idiopathic unilateral hyperlucent lung were reported: The clinical pictures and X-ray findings were analysed. The main X-ray changes were abnormal hyperlucency of the affected lung or lobe while the size of the hyperlucent lung was normal or smaller than the contralateral side. The hilar shadow and vascular ...

A patient with a unilateral hyperlucent lung with acute respiratory complaints is presented. A ventilation-perfusion scan was performed to rule out pulmonary embolism. The perfusion scan ( [99mTC]MAA) showed peripheral perfusion defects in the hyperlucent lung. The ventilation study (133Xe) demonstrated peripheral ventilatory defects on the single breath image in ...

Twenty-four of 230 patients with patent ductus arteriosus had hypovascularity and hyperlucency in the left lung on preoperative chest roentgenograms. Two of the 24 patients died shortly after operation, and one was unavailable for follow-up. During the postoperative course (mean, three years), roentgenograms of eight of the remaining 21 patients ...

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 ...

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. 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 ...

When diagnosing unilateral hyperlucency on a X-ray picture one of the possible underlying conditions is the Swyer-James Syndrome. It consists principally of hyperlucency, diminished size, deficient blood supply, decreased ventilation, and bronchiectasis of the affected lung. Frequently a preceding pneumonia, caused by adenovirus, seems to be of aetiological importance. A ...

Lower respiratory infections in infancy caused lung emphysema in a 10-year old girl; being a locus minoris resistentiae the emphysema led to recurrent pulmonary complaints. This corresponds to the definition of the Swyer-James or McLeod Syndrome. The radiologic clue to the diagnosis is often the "unilateral hyperlucent lung", which is ...

A cases of unilateral hyperlucent lung syndrome (Swyer-James', MacLeod's syndrome) in a 45-years old male patients is presented. The patient was being treated since 1982 because of recurrent upper and lower respiratory tract's infections. An increasing dyspnea was the main patient's manifestation. In 1997 the patient was admitted to the ...

The paper presents the picture of the unilateral or partial "hyperlucent lung" syndrome. The most common causes of this anomaly are described according to pathological and anatomical criteria. The difficult diagnosis of its X-ray-appearance is discussed. The value of differential diagnostic criteria is demonstrated in suitable cases. Differentiation from the ...

Pneumocystis carinii pneumonia (PCP) presented as unilateral hyperlucent lung in a 27-month-old patient with a brain tumor who was receiving chemotherapy. Although unilateral pneumonia is an uncommon presentation of PCP in non-AIDS patients, PCP must be suspected in any pediatric cancer patient not receiving trimethoprim-sulfamethoxazole prophylaxis and receiving intensive chemotherapy.

The occurrence in a young patient of a chronic cough with dyspnoea and restrictive ventilatory failure as shown by respiratory function tests suggested the possibility of a Mac Leod syndrome. However, other aetiologies could be considered such as vascular malformations, bronchial malformations and also tumours. If the chest X-ray sometimes ...

Seventeen children with unilateral hyperlucent lungs were referred for investigation. Of the 11 who had a referring diagnosis of possible Macleod's syndrome only two were shown to have post-viral bronchiolitis. Three of the 11 had conditions that required surgical treatment and a further two with brochiectasis were treated medically. To ...

A variety of congenital and acquired etiologies can give rise to the radiographic finding of a unilateral hyperlucent lung. An unusual case of congenital lobar emphysema diagnosed in a young adult following the initial discovery of a hyperexpanded, hyperlucent lung is reported. Although subsequent bronchoscopy and radiologic studies detailed extensive ...

She has diagnosed asthma and since 1997 she has been treated with inhaled corticosteroids and long-acting beta-agonists without improvement. She complained of a cough, shortness of breath, pulmonary function test reveal irrvesibility airflow obstruction. The routine X-ray chest ...

Swyer-James syndrome is a pulmonary condition acquired following bronchiolitis obliterans early in life. Clinically characterized by repeated bouts of pulmonary infections, Swyer-James syndrome is characterized radiographically by a unilateral small, hyperlucent lung that demonstrates diminished arterial supply to the involved lung, air-trapping, and bronchiectasis. Radioimaging procedures may reveal otherwise unsuspected ...

Disproportionate emphysematous involvement of the lung bases, compared with the apices, sometimes called basilar hyperlucency, is an unusual radiographic pattern that has been reported primarily in patients with alpha-1 antitrypsin deficiency, but also in individuals with emphysema caused by intravenous injection of methylphenidate. We present a patient with emphysema associated ...

A clinical series of 40 consecutive patients with chronic unilateral hyperlucent lung was analysed. Swyer-James (MacLeod) syndrome turned out to be the most common diagnosis (18 patients, 45%). Other causes were localized emphysema (8 patients, 20%), congenital hypoplastic pulmonary artery (4 patients, 10%), previous massive pulmonary embolism (4 patients, 10%), ...

OBJECTIVES: Unilateral hyperlucent lung on chest radiograph is uncommon in children. It is often found incidentally and always refers to Swyer-James syndrome, with decrease in pulmonary vascularity and air trapping during expiration. However, it may occasionally mimic other serious lung diseases such as pulmonary hypoplasia/aplasia, defect of pulmonary artery, and ...

Swyer-James-MacLeod Syndrome (SJMS) is considered to be a relatively uncommon and complex disease characterized by roentgenographic hyperlucency of one lung, lobe, or part of a lobe, due the pulmonary vascular structure and alveolar overdistension. It is sometimes associated with bronchiectasis. This syndrome seems to be an acquired disease that develops ...
