[Chylothorax after pressure pneumothorax].

Chylothorax is a pleural effusion caused by leakage of chyle into the pleural cavity. The commonest causes of pleural effusion are trauma to the ductus thoracicus or neoplasms in the mediastinum. The trauma can be iatrogenic or accidental. Chylothorax caused by tension pneumothorax has not previously been reported. We describe a case where this etiology is the most likely explanation of the chylous effusion in our patient.
