Purpose: This study aims to evaluate the importance of preoperative radiological findings in the distinction between giant lipom and low-degree liposarcoma and to identify the appropriate surgical method. Methods: 59 patients with marginal and broad recession due to huge lipoma (21 women, 15 men) and low-degree liposarcoma (14 women, 9 men) were considered retrospective. Pre-biopsy radiological findings were studied using magnetic resonance images. Pre- and postoperative functional results were evaluated using the Upper Extreme Functional Index (UEFI), the Lower Extreme Functional Index (LEFS) and the Visual Analogo Scale (VAS). Based on the marginal and broad recession of these lesions, functional results were assessed. Results: According to preoperative radiological findings, there was no meaningful relationship between thin septa and giant lipoma or low-degree liposarcoma. But there was a meaningful relationship between the appearance of a thick spine and globular area in low-degree liposarcoma and the appearance of homogeneous mass in giant lipom patients. Postoperative middle-term UEFI, LEFS and VAS scores were significantly better than preoperative functional results for marginal and broad recession. There was no difference between preoperative and postoperative mid-term functional results in both lesions in marginal and broad resections. Local nuts were detected in four low-degree liposarcoma patients with marginal resection. The study found that the thick septum, the globular area and nonadiposis mass for low-degree liposarcoma, and the homogeneous mass for the giant lipom, were distinguishing. However, it will be more convenient to treat low-degree liposarcoma with extensive surgical resection.
