We reviewed our experience with fiberoptic bronchoscopy (FOB) in patients with pleural effusion of unknown origin. Seventy patients underwent FOB for the investigation of pleural effusion between 1978 and 1983. Those with a second reason for FOB, a mass on chest roentgenogram, or lobar atelectasis were excluded. Forty five patients remained: 28 patients with unexplained pleural effusion after p...

Bronchogenic cysts are generally detected shortly after birth or in early childhood. Most lesions are found in the mediastinum, along the tracheobronchial tree or in the lung parenchyma. Cutaneous or subcutaneous bronchogenic cysts are rarely reported. Our patient was the second case in the English literature who had a cyst over the manubrium sterni in adult life. Surgical total excision is the...

Flexible transbronchial needle aspiration (TBNA) provides access to mediastinal lymph nodes, but its role in staging bronchogenic carcinoma is unknown. To determine the efficacy and safety of this procedure for staging the extent of mediastinal disease, the results of TBNA performed during fiberoptic bronchoscopy in 39 patients without known extrathoracic metastases were reviewed. Flexible TBNA...

The HL-A antigens were determined retrospectively in a group of 14 surgically cured bronchogenic carcinoma patients and prospectively in another group of 100 untreated patients. In the retrospective group, the frequencies of antigens W-19 and HL-A5 were significantly increased when compared with the noncancer control and the prospective lung cancer populations. In the latter group, 60% of the p...

Mediastinoscopy was carried out in 400 cases, including 296 of bronchogenic carcinoma. At the time of presentation the new growth had already spread to involve the mediastinal lymph nodes in slightly more than 50% of these. The incidence of involvement was 76% in oat-cell and 35% in squamous-cell carcinoma. Non-resectability at thoracotomy was encountered in seven out of 120 patients. We advoca...

Purpose: To evaluate the clinical usefulness of steady-state free-precession (SSFP) sequence for differentiating bronchogenic carcinoma from adjacent atelectasis. Methods: Ten patients with bronchogenic carcinoma and adjacent atelectasis underwent unenhanced magnetic resonance imaging (MRI). MRI examinations using the SSFP sequence, T2-weighted imaging (T2WI), and diffusionweighted imaging (DWI...

Serum potassium concentration was normal (greater than or equal to 3.6 mmol/l) in 29 of 32 patients with the syndrome of inappropriate antidiuretic hormone excess (SIADH) associated with a bronchogenic carcinoma. In 11 of the patients there was no significant change in serum potassium concentration after correction of the syndrome, by fluid restriction. Hypokalaemia is thus an uncommon finding ...
