AbstractBackground Retroperitoneal cysts (RPCs) are uncommon with an estimated incidence of
1/5750 to 1/250,000. In this entity, non-pancreatic pseudocyst are the rarest with only
handful of cases reported in literature, out of which all were found in males. Most of the
time they are discovered incidentally and diagnosis depends in part histologically on
absence of an epithelial lining to the cyst wall, and the patient’s history represents the
cornerstone for diagnosis prediction.
Case presentationA 27 year old, female patient presented to the Gynaecology out patient
department with complaints of amenorrhea for 2 months & lower abdominal discomfort.
On investigation, there was an incidental finding of a large multi-cystic lesion arising from
the pelvis on transvaginal ultrasound scan. The patient was then referred to the General
Surgery department for further management. Correlation of the clinical scenario, imaging
and post- operative histopathological examination of the specimen, revealed
Retroperitoneal Non-pancreatic Pseudocyst.
ConclusionRPC’s are very rare, and probably remain quiescent, until attain considerable
size. Usually, symptoms are non-specific and on examination there may be a palpable,
freely mobile abdominal mass. Sometimes, subjected to one of its classical complications
such as infection, rupture or haemorrhage enforcing the patient to seek urgent medical
advice. In view of potential development of symptoms and complications, the treatment
protocol lines with complete excision of the cyst in order to prevent any recurrence.
