Diaphragmatic hernia originates from insufficient closure of the pericardioperitoneal canals and pleuroperitoneal membranes. It is seen in one in every 4000 births. The general finding in the newborn period is respiratory difficulty. Mortality is 40–50%. There may be other accompanying organ anomalies. Congenital diaphragmatic hernias diagnosed after the newborn period are known as late-presenting congenital diaphragmatic hernias. This group is seen at a level of 5–20% and poses difficulty in diagnosis. This report describes a case under observation and receiving treatment for gastrointestinal haemorrhage, diagnosed as Bochdalek hernia.
