Nephrobronchial fistula and lung abscess secondary to Xanthogranulomatous pyelonephritis

Abstract

There are multiple causes of lung abscess, but the differential rarely includes pyelonephritis as a primary cause leading to lung abscess resulting from the development of a nephrobronchial fistula. The patient had no urinary symptoms or abdominal pain and the etiology of lung abscess was only incidentally discovered after chest CT revealed extension of pleural fluid below the diaphragm.
