Subphrenic abscess: a pulmonary presentation.

A patient with subphrenic abscess can present with pulmonary or abdominal symptoms because of the location of the abscess adjacent to the diaphragm. This thoracoabdominal clinical complex has been described previously and, if chest symptoms predominate, may obscure the diagnosis of subphrenic abscess. The case of a patient with occult abdominal pathology who presented with respiratory complaints is discussed.
