Left-sided congenital diaphragmatic hernia: delayed presentation.

Seven patients with left-sided congenital diaphragmatic hernias at ages of 2--20 months are reported and five are described in detail. Radiographic findings were classic in one patient, but simulated inflammatory chest disease in two patients, gastric volvulus in three patients, and a pneumothorax in one patient. These misleading appearances if not recognized can lead to incorrect radiographic interpretation and in some cases inappropriate treatment.
