Retroperitoneal cystic teratoma masquerading a pancreatic Pseudo cyst: A Case Report

Retroperitoneal cystic teratoma

Abstract

Background: Primary retroperitoneal teratomas constitute about 1-11% of all primary retroperitoneal tumours. Retroperitoneal cysts (RPCs) are uncommon with an estimated incidence of 1/5750 to 1/250,000 and have versatile presentation.
Case History: A 34-year old male presented with insidious onset upper abdominal lump & occasional dull aching pain for 4 months. On examination, a large rounded ,non mobile cystic mass measuring 7cm in diameter was palpable in upper abdomen involving the epigastric and left hypochondrium. This case is very rare and very educational as it highlights an unusual presentation of male patient having benign retroperitoneal cyst which simulates pancreatic pseudocyst. Conclusion: Retroperitoneal teratoma is one of the rare entities. Due to wide space of origin toumour has nonspecific presentation & though very rare sometimes toumours may simulate with pancreatic pseudocyst due to similarity in clinical features . It needs multi-disciplinary approach for the accurate diagnosis and management.
