title: Recurrent noisy pneumothorax mimicking pericarditis.
abstract: Sounds related to the cardiac cycle may have an extra-cardiac origin. We report a case of recurrent noisy pneumothorax producing a loud rub, audible at a distance from the patient and initially diagnosed as pericarditis. The sounds and their mechanisms of production in this condition are also discussed.
