1. Retroperitoneal liposarcoma recurrence can be extremely subtle; by viewing this exhibit the reader will increase their awareness of early signs of recurrence. 2. Localised increase in fat is the most commonly missed sign of liposarcoma recurrence. It may present as separation of bowel loops, displacement of solid viscera or widening tissue interfaces. 3. Serial computed tomography may show only very slow enlargement of soft tissue nodules or increase in soft tissue stranding which can be missed unless all historic examinations are reviewed. 4. We discuss the common post operative findings, which if stable over the follow up period, are considered to be benign post surgical changes.  

1. Background of retroperitoneal liposarcoma 2. Our experience: We are a large supra regional oncology centre, with extensive experience in the surgical management of retroperitoneal liposarcoma. We present our experience of imaging follow up of 112 cases of retroperitoneal liposarcoma over a 7 year period. 3. Imaging Serial CT is the mainstay of follow up after initial radical surgery, with an aim of early identification of recurrences to allow further curative surgery. We provide examples of subtle recurrences and highlight the teaching points in each case. 4. Summary
