Abstract
Diaphragmatic hernia is a congenital malformation, often discovered in the neonatal period, and its occurrence in adults is very rare. This patient, who was completely asymptomatic until the age of 62, had developed an intestinal obstruction and went into respiratory failure after surgery for an external auditory canal carcinoma. He was subsequently diagnosed with a late-presenting congenital diaphragmatic hernia (CDH), thus requiring surgical treatment. Anesthesiologists and critical care physicians should keep in mind the possibility of CDH as well as diaphragmatic relaxation when an unexplained elevation of the diaphragm is observed perioperatively.
