ABSTRACT: A rare syndrome, Chilaiditi's syndrome is interposition of the colon only or with the small intestine in hepatodiaphragmatic area. It may be asymptomatic, but it may also present with symptoms, such as abdominal pain, nausea, vomiting, constipation and respiratory distress. We present a patient who was admitted with urological problems; he was incidentally diagnosed with Chilaiditi's syndrome.Canadian Urological Association journal = Journal de l'Association des urologues du Canada 04/2012; 6(2):E75-6. · 1.66 Impact Factor

A 58-year-old man presented to the Emergency
Department with a two-day history of vomiting, diarrhea
and intermittent central abdominal pain. His background
history was significant for peptic ulcer disease. On
examination there was diffuse abdominal tenderness, and
a fecal occult blood test was positive. A departmental
chest radiograph had appearances suggestive of a
pneumoperitoneum, with an elevated right hemidiaphragm
and subdiaphragmatic free air. The patient was referred to
the surgical team for management of a suspected perforated
Subsequent CT imaging of thorax and abdomen revealed
hepato-diaphragmatic interposition of the transverse colon,
as well as extensive colitis. He was managed conservatively
and discharged home well after four days.
Chilaiditi’s sign is the appearance of free air under the
diaphragm caused by interposition of the transverse colon
between the liver and diaphragm. It is usually asymptomatic
and is an incidental finding. It is estimated to occur in 0.25%
to 0.28% of the general population1 and was first described
by Demetrious Chilaiditi in 1910.2 When the sign is observed
in association with symptoms such as abdominal pain or
vomiting it is termed Chilaiditi’s syndrome. It is in this
scenario that the radiographic findings may be mistaken for
pneumoperitoneum, as occurred in this case.
