Although retroperitoneal sarcomas are rare tumours, they can be encountered by a wide variety of clinicians as they can be incidental findings on imaging or present with non specific symptoms and signs. Surgical resection can offer hope of cure and patient outcomes are improved when patients are managed in high-volume specialist centers. Failure to recognize retroperitoneal sarcomas on imaging can lead to inappropriate management in inexperienced centers. Therefore it is critical that a diagnosis of retroperitoneal sarcoma should be considered in the differential diagnosis of a retroperitoneal mass with prompt referral to a soft tissue sarcoma unit. In particular, the most common retroperitoneal sarcoma subtypes, liposarcoma and leiomyosarcoma, have characteristic imaging appearances which are discussed. This review therefore aims to set the context and guide clinicians through a diagnostic pathway for retroperitoneal masses in adults which arise extrinsic to the solid abdominal viscera.
尽管腹膜后肉瘤是罕见肿瘤，但各类临床医生都可能遇到，因为它们可能是影像学检查中的偶然发现，或者表现为非特异性症状和体征。手术切除可带来治愈希望，在大容量专科中心对患者进行管理时，患者的预后会得到改善。在影像学检查中未能识别腹膜后肉瘤可能导致经验不足的中心进行不恰当的处理。因此，在鉴别诊断腹膜后肿块时，至关重要的是应考虑腹膜后肉瘤的诊断，并迅速转诊至软组织肉瘤科。特别是，最常见的腹膜后肉瘤亚型，脂肪肉瘤和平滑肌肉瘤，具有特征性的影像学表现，本文将对此进行讨论。因此，本综述旨在为成人腹部实质性脏器外源性腹膜后肿块的诊断途径提供背景信息并指导临床医生。
