INTRODUCTION Retroperitoneal sarcomas Are uncommon tumours, accounting for 10-15% of soft tissue sarcomas, with 2.7 cases per million. Usually presents in their 50s, but age range is broad. Equal frequency in men and women. 80% of retroperitoneal neoplasms are malignant. Clinical Present[...]

PRE-OPERATIVE DIAGNOSIS AND STAGING: IMAGING PRINCIPLES Accurate pre-operative imaging impacts survival by helping surgeons plan complete R0 resection and planning radiotherapy for non resectable cases. CT scan of chest, abdomen and pelvis is the preferred tool for tumour detection, staging, g[...]
RPS are uncommon and typically present late. CT scan is the firstline modality in staging and follow-up. Imaging clues to histological subtypes like retroperitoneal liposarcoma and leiomyosarcoma are often present. Most RPS resections involves concomitant resection of at least one visceral organ[...]
