[Radiographic appearance of fluid in the pleural space].
Observations of the diagnostic procedures of 397 patients treated due to the pleural effusion have been presented. Some of the methods were very differential. Pleural effusions were not only an etiological problem but sometimes the morphological identification is very difficult because of the atypical view of the radiologic appearance. X-ray examinations of the effusion in many projections enables differentiation from other cases. In cases where clinical and X-ray examinations cannot be performed different procedures like transthoracic tap and explorative thoracotomy should be performed.
