    Abstract:
    Pulmonary emphysema is anatomically defined as abnormal persistent enlargement of the air spaces distal to the terminal bronchioles, accompanied by destruction of alveolar walls, without evident fibrosis. High-resolution computer tomography (HRCT) imaging is a valuable tool for diagnosis of this disease. The presence of minute cysts distributed evenly through all lung zones is rarely observed in pulmonary emphysema. In such cases, emphysema should be differentiated from other cystic lung diseases. We present a case of a 45-year-old women admitted to our Department with dyspnoea on exertion. Physical examination revealed no abnormalities. A chest radiograph showed diffused interstitial lesions in both lungs; HRCT revealed multiple oval-shaped cysts equally dispersed in all lung areas. The pulmonary function tests revealed increased lung volumes (total lung capacity 114.6% predicted, residual volume 200.6% of predicted), while both vital capacity and FEV1 were decreased (73.6% and 54.0% of predicted volumes, respectively). Diffused lung capacity was normal. Trans-bronchial biopsy was non contributory. Histiological examination of lung tissue obtained by videothoraco-scopy (VTS) was diagnostic for bullous emphysema. The patient had prescribed ipratropium bromide and teophyline. Differential diagnosis, apart from pulmonary emphysema, should take into consideration lymphangioleiomyomatosis, histiocytosis and sarcoidosis.
