INTRODUCTIONRetroperitoneal soft tissue sarcomas (RPS) are frequently incidental findings on imaging for non‐related symptoms or diseases and can grow to a large size in the retroperitoneum before symptoms or signs of abdominal pain, back pain, bowel obstruction or a palpable abdominal mass develop. RPS are rare and account for approximately 12‐15% of all soft tissue sarcomas with a mean incidence of 2.7 per million. Therefore the radiologist and clinicians involved in the patients care at presentation may not have experience of the imaging appearances. Failure to recognize RPS on imaging can lead to inappropriate management in inexperienced centres. This can have catastrophic consequences due to incomplete resections or contamination of the patients peritoneal cavity with tumor which jeopardizes the patients chance of a curative operation. After tumor grade, the long‐term survival following RPS resection is most dependent on the completeness of surgical resection. Other important factors are patient age, tumor subtype, tumor size, multifocality, and centralized multidisciplinary management in a specialist sarcoma center. Therefore early referral is advisable.DIAGNOSTIC IMAGING TECHNIQUESComputed tomography (CT)CT allows confirmation of site and origin of the mass and often tissue composition ie, lipomatous elements, calcifications or myxoid elements. Particularly where large masses distort anatomy, distinction
