J86: Pyothorax

J86.0: Pyothorax with fistula

The lungs are surrounded by a smooth membrane. A smooth membrane like this is also located inside the ribs. Both membranes cling to each other via a small amount of fluid. Through the suction of the fluid between the membranes, the lungs follow the movements of the chest while breathing. The lungs then alternately expand and contract. Air for breathing flows into the lungs and out again during these movements.

In your case, there is pus between both membranes around the lungs. This pus is caused by an inflammation. This inflammation is usually caused by pathogens.

In your case, a connecting passage has additionally formed. Such a passage connects two locations in the ribcage that are not normally connected together. For example, a passage to the pulmonary tissue may be formed from the space between the smooth membranes. Or a passage may be formed from the windpipe to the gullet.
