This study examines the value of different imaging methods in assessing the anatomic structures of unilateral hyperlucent lung due to obliterative bronchiolitis. We studied 9 patients, 5 males and 4 females, suffering from UHL (mean age 49 years). Ventilation-perfusion scan (VPS) and computed tomography (CT) of the chest were performed in all, and conventional angiography or digital substraction angiography (DSA) in 7 patients. The VPS showed the characteristic pattern of a matched ventilation-perfusion defect and considerable air trapping during the washout phase. Conventional angiography and DSA displayed a smaller pulmonary artery on the affected side, with a poor peripheral vasculature. CT displayed a loss of lung volume in all cases, with diminished mean attenuation values, a markedly diminished vasculature and integrity of the main airways. In contrast to other imaging modalities, CT imaged bronchiectasis, which was the cause of the patients' clinical symptoms of bronchorrhea and hemoptysis. We conclude that CT of the chest is the most valuable imaging method for evaluating unilateral hyperlucent lung, particularly in symptomatic patients.

Bronchioloalveolar carcinoma is characterized pathologically by a pulmonary neoplasm showing lepidic growth. More than half of all patients with bronchioloalveolar carcinoma are asymptomatic. The most frequent symptoms and signs are cough, sputum, shortness of breath, weight loss, hemoptysis, and fever. Bronchorrhea is unusual and a late manifestation. Nonmucinous bronchioloalveolar carcinoma tends to be more localized and has a lower frequency of bronchogenic spread than mucinous bronchioloalveolar carcinoma. Bronchioloalveolar carcinoma appears radiographically as a single nodule, segmental or lobar consolidation, or diffuse nodules. At computed tomography (CT), the single nodular form appears as a peripheral nodule or localized ground-glass attenuation with or without consolidation, frequently associated with bubblelike areas of low attenuation and open bronchus signs. The lobar consolidative form may demonstrate the CT angiogram and open bronchus signs. The diffuse nodular form appears as multiple nodules or areas of ground-glass attenuation or consolidation. The single nodular form has a better prognosis than the others but may show false-negative results for malignancy at 2-(fluorine-18) fluoro-2-deoxy-D-glucose positron emission tomography.

Respiratory symptoms such as dyspnea, coughing, bronchorrhea, hemoptysis and death rattle are a common problem in palliative medicine. Their prevalence increases markedly in terminal phase oncological patients. In such cases, new therapeutic methods with lower toxicity and well documented efficiency in the control of respiratory syndrome should be considered.
