Patient is admitted for bilateral pneumonia and has a fever. Fever did not respond to antibiotic treatment.

On the ultrasound examination thickened pleura pressing on the heart with hypoechoic oval structures and septa moving in connection with cardiac contraction. Due to the fact that the temperature did not reduce during antibiotic therapy, a thin drain was inserted during an ultrasound examination, and at the same time a pleural biopsy was performed. Next the drain was flushed (material from the flushing can be seen on the picture); on the day after the drainage the patient was completely afebrile. In the check-up ultrasound examination there was a regression of the thickened pleura and the hypoechoic area gradually disappeared. The histological examination found an abscessing inflammation. On the video after drainage we can see the flushing solution filling the area, how the area enlarges as the solution is applied, and how the area flattens as the solution is suctioned out.
