A 17-year-girl presented with recurrent pain in abdomen of 10-year duration. The pain used to start as dull ache on right side of her abdomen, which gradually would increase over few hours to become moderately severe. This was not associated with nausea, vomiting, abdominal distension, respiratory, bowel or urinary symptoms, jaundice or fever. The pain usually lasted for 4-6 hours and subside on its own mostly or at times with oral analgesics. Such episodes became more frequent with increasing severity of pain from last 2 years. She visited many local practitioners for same to no avail. On careful evaluation, she revealed history of significant blunt trauma to abdomen at the age of 5 years due to fall from a swing.
General physical examination, chest and abdominal examination were unremarkable. Her routine hematological investigations were within normal limits. Chest X-ray suggested right diaphragmatic hernia. A contrast enhanced CT scan showed partially fractured right lobe of liver with heterogeneous enhancement herniating into the right pleural cavity through a diaphragmatic tear. The rest of the right lobe was normal but the left lobe was peculiarly enlarged reaching the left lateral abdominal wall and then curving around the spleen (Figure 1A). Other abdominal viscera were normal.
On abdominal exploration, a significant portion of the right lobe of liver was found fractured that had herniated into the right thoracic cavity through a diaphragmatic rent measuring 8x4 centimeters. This segment could be delivered into the abdomen by enlarging the diaphragmatic defect and adhesiolysis. The herniated segment was congested that explained its heterogeneous appearance on CT scan (Figure 1B). The left lobe of liver was hypertrophied, reaching beyond the splenic flexure and draping around the spleen. The rest of abdominal viscera was normal. The diaphragmatic tear was repaired primarily using polypropylene suture. The post-operative course was uneventful and the girl was discharged after 3 days. At 6 months of follow-up she is asymptomatic.

Right sided diaphragmatic hernias are rare due primarily to the protective effect of the liver [1,2]. They are mostly asymptomatic and may remain undiagnosed for long. It is reported that this delay may be as long as 50 years [2]. At times they may present with non-specific symptoms like abdominal pain, respiratory difficulty and bowel symptoms after variable period from injury, so a history of trauma must be taken in such patients. This proved crucial in our case. The abdominal pain in our patient and the hypertrophy of left lobe of liver may be explained by chronic ischemia of the herniated portion of the liver. This is also supported by its congested appearance. Once diagnosed, the hernia should be repaired either primarily or using a synthetic mesh by open or laparoscopic approach [3].
