Dilated sigmoid colon with Chilaiditi's sign mimicking diaphragmatic hernia: A case report

Chilaiditi's sign is a rare radiological presentation characterized by colonic interposition between the diaphragm and liver which is usually confused with conditions such as diaphragmatic hernia, pneumoperitoneum and subdiaphragmatic abscess.

We report a case of 55 year old male presenting with abdominal pain since a year which was associated with abdominal fullness, loss of appetite and constipation. Further investigations showed us as a case of diaphragmatic hernia but intra operatively it was found to be Dilated sigmoid colon with Chilaiditi's sign.

It is a rare incidental finding with major preponderance in male. The intestinal, hepatic and diaphragmatic causes predispose its pathology. Conservative management is the first line of treatment but the complicated abdominal pathologies are managed by various surgical intervention.

Dilated sigmoid colon along with Chilaiditi's sign can sometime mimic as Diaphragmatic hernia which can make enormous difference in our pre and post-operative diagnosis. Chilaiditi's syndrome is a rare entity so early diagnosis is of utmost benefit.
