Cough in a patient with an infusion port.

In this case report, we describe a patient with a history of fallopian tube adenocarcinoma who had an infusion port in place for the past 4 years. During the course of her stay in the hospital for pneumonia, she developed a cough that became worse with the infusion of fluids through the port. A portogram done to investigate this problem revealed the presence of a portobronchial fistula. This is the first reported case of a portobronchial fistula. Various possibilities to explain the formation of portobronchial fistula are discussed.
