[Dystrophic hyperlucent lung (author's transl)].

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 operated. They showed that surgery provided many improvements and that making a pleural adhesion during the intervention limited the bullous evolution of the disease. Results plead in favour of early interventions and wider indications.

Chronic unilateral hyperlucent lung. A consecutive series of 40 patients.

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%), bronchial carcinoma (3 patients, 7.5%), sequelae of radiation therapy (2 patients, 5%) and benign intrabronchial neoplasm (1 patient, 2.5%). The reduction of pulmonary vasculature was scored (0-9). The most extensive reduction was found in patients with Swyer-James syndrome (mean 5.8), whereas patients with bronchial cancer had the smallest changes (mean 3.0).

Hyperlucent lung secondary to homocystinuria.

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 subsequently shown to be present in the surviving twin as well. A ventilation/perfusion lung scan of the surviving twin revealed multiple ventilation/perfusion mismatched defects, suggestive of pulmonary embolism. The presenting manifestation of homocystinuria in these patients was the pulmonary thrombotic disease. Neither twin had any other stigmata of homocystinuria at the time of initial presentation.

Transient unilateral hyperlucent lung due to mucus plugs.

A 63-year-old patient with a tracheostomy presented with a transient unilateral hyperlucent lung and absent breath sounds over the left lower lobe. A tracheobronchial cast and an additional floating mucus plug in the left lower lobe bronchus were retrieved with fiberbronchoscopy. Subsequently normalisation of ventilation and radiological appearance of the left lung occurred.

Unilateral hyperlucent lung (Swyer-James syndrome) after severe Mycoplasma pneumoniae infection.

An 11-year-old girl contracted pneumonia with consolidation of the left lower lobe, infiltrates in the lingula and left upper lobe, and a large left pleural effusion, accompanied by a Mycoplasma complement-fixation titer increasing to 1:16,384. Serial chest radiographs demonstrated resolution of the pneumonia and effusion, followed by development of a hyperlucent left lower lobe. This diagnosis was supported by abnormalities discovered by chest cinefluoroscopic examination and lung scans of ventilation and perfusion. Unilateral hyperlucent lung should be considered as a possible sequel to severe Mycoplasma pulmonary infection.

[Unilateral hyperlucent lung].

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 left hilar shadow. We considered the diagnosis of Mac Leod's syndrome after eliminating a proximal obstructive pathology and pulmonary embolus. Mac Leod's syndrome or Swyer James' syndrome was described in 1954 and is suggested on the standard radiograph above all if the expiratory films have confirmed the presence of air trapping. Angiography shows a slender and fine pulmonary network. Computer tomographic examination of the chest rules out a bronchial tumour, excludes bullous emphysema and reveals hyperlucent zones. Scintigraphy with ventilation perfusion supplies the essentials to understanding the mechanism (a syndrome of aerated lung which is neither directly ventilated nor perfused). The expiratory function tests most often show a restrictive syndrome but sometimes an obstructive syndrome is found with associated air trapping. The disorder does not progress and the prognosis is good.

Unilateral hyperlucent lung with decreased vascular markings (Swyer-James syndrome).

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 yound patient, in whom the Swyer-James Syndrome was diagnosed on clinical, radiological, angiographical and ventilatory symptoms, suffered from pneumonia shortly before. This pneumonia was probably caused by adenovirus type 7, as appears from this virus being isolated from the faeces at that time. Treatment of this condition consists of antibiotics, mucolytics, bronch-spasmolytis, and physiotherapy. Surgery is rarely indicated.
