A case of nephrobronchial and colonobronchial fistula presenting as lung abscess.

A nephrobronchial fistula is an uncommon clinical entity and perinephric abscess in the most common etiological lesion. At times, pulmonary symptoms may dominate the clinical picture and the diagnosis of an associated renal lesion may be overlooked. An unusual case of a coexisting nephrobronchial and colonobronchial fistula is reported. The patient had been treated for chronic lung abscess for 4 years before the final diagnosis was made.
