Background

B
Enterogenous cyst is - rare congenital
lesion of endodermal derivation - related
to intrauterine volvulus with subsequent
ischemia and infarction persistence of
intrauterine diverticulum incomplete
vacuolization of solid alimentary tract Complete
isolated enterogenous cyst - rare variant
of enteric duplication cyst Unrecognized ,
asymptomatic cysts be the site of adenocarcinoma
during adult life. Coexistence of a
enterogenous cyst with a classic enteric
duplication cyst - has been reported only
twice earlier in the literature

Case

• An 9-month-old russian boy presented with chronic
  constipation and prenatal detected
  intra-abdominal cystic mass. He gave a history of
  constipation after starting solid food and a
  gradual increase in the intra-abdominal mass size
  past nine months(0.9-gt8.0 cm).
• A simple abdomen film showed gas distended bowel
  loop in the upper abdomen(Figure 1).
• Untrasound showed multilobulated and septated
  cystic lesion with internal debris in right upper
  abdomen(Figure 2).

Under the impression of retroperitoneal cystic
lymphangioma and enteric duplication cyst, the
operation was conducted. Operative finding
revealed pancreatic origin mass rather than
cystic lymphangioma. Gross specimen pictures A.

• A Computed tomography scan confirmed and
  retroperitoneal cystic mass but could not comment
  on the origin. It showed features of a cystic

Histopathology of the A. retroperitoneal cystic
mass revealed congenital enterogenous cyst having
esophagus, stomach and colonic wall, while the B.
duplication cyst adjacent to cecum had
heterotopic gastric tissue and partly
communicated with colonic wall

This represents third case in the literature of
retroperitoenal enterogenous cyst with enteric
duplication cyst. Awareness of varied
presentation of enterogenous cysts wound help in
appropriate management during surgery without any
confusion.
