Resolution of a complex mediastinal pseudocyst in a patient with alcohol-related chronic pancreatitis following abstinence from alcohol.

We describe a 55-year-old patient with alcoholic chronic pancreatitis, a large mediastinal pseudocyst and a hemorrhagic pleural effusion. A single thoracocentesis and withdrawal of alcohol without other conservative or invasive measures resulted in a complete resolution of the pleural effusion and the mediastinal pseudocyst, which to our knowledge has not been described before.
