duplications of the alimentary tract are well - known but rare congenital
malformations that can occur anywhere in the gastrointestinal ( gi ) tract
from the tongue to the anus . while midgut duplications are the most
common , foregut duplications such as oesophagus , stomach , and parts 1
and 2 of the duodenum account for approximately one - third of cases .
they are most commonly seen either in the thorax or abdomen or in both as
congenital thoracoabdominal duplications . cystic oesophageal duplication
( ced ) , the most common presentation , is often found in the lower third
part ( 60 - 95% ) and on the right side [ 2 , 3 ] . hydatid cyst ( hc ) is
still an important health problem throughout the world , particularly in
latin america , africa , and mediterranean areas . turkey , located in the
mediterranean area , shares this problem , with an estimated incidence of
20/100 000 . most commonly reported effected organ is liver , but in
children the lungs are the second most frequent site of involvement [ 4 ,
5 ] . in both ced and hc , the presentation depends on the site and the
size of the cyst . hydatid cysts are far more common than other cystic
intrathoracic lesions , especially in endemic areas , so it is a challenge
to differentiate ced from hc in these countries . here , we present a
7-year - old girl with intrathoracic cystic mass lesion , who had been
treated for hydatid cyst for 9 months , but who turned out to have
oesophageal cystic duplication . a 7-year - old girl was referred to our
clinic with coincidentally established cystic intrathoracic lesion during
the investigation of aetiology of anaemia . the child was first admitted
with loss of vision in another hospital ten months previously . the
patient 's complaints had been attributed to pseudotumour cerebri due to
severe iron deficiency anaemia ( haemoglobin : 3 g / dl ) . chest
radiography and computed tomography ( ct ) images resulted in a diagnosis
of cystic intrathoracic lesion ( fig . the cystic mass was accepted as a
type 1 hydatid cyst according to world health organization ( who )
classification . after 9 months of medication , no regression was detected
in ct images , so the patient was referred to our department . an ondirect
haemagglutination test result was again negative . during surgery , after
left thoracotomy incision , a semi - mobile cystic lesion , which was
almost seven centimetres in diameter , with smooth contour , was found
above the diaphragm , below the lung , outside the pleura ( fig . the
entire fluid in the cyst was aspirated ; it was brown and bloody ( fig . 2
) . the diagnosis of cystic oesophageal duplication was considered , and
so an attachment point was searched for . it was below the hiatus , on the
lower third left side of the oesophagus , and it also was excised
completely through the hiatus . pathologic analysis of the specimen showed
oesophageal mucosa with an underlying proper smooth muscle layer.
