Yashaswini Basaboina, Rohini Avansta, Abhimanyu B. Punja

Abstract: Objective: This study aims to determine the different imaging features of the retroperitoneal liposarcomas and categorize the histopathological type based on these features. Methods: A retrospective study was performed in Justice K. S. Hegde Charitable Hospital on 10 patients who were histopathologically proven to have retroperitoneal liposarcomas who had also undergone CECT abdomen and pelvis. Results: Out of 10 cases with HPE - proven liposarcoma of the retroperitoneum, the CT features favoring RPS are 90% of the lesions were more than 5 cm, 80% of the lesions were fat density lesions showing heterogenous enhancement, and involving the adjacent structures.7 lesions were having well - defined lobulated margins.50 - 60% of the lesions were having calcifications and internal enhancing septae within. Also in our study 30% were HPE was proven to be well - differentiated RPS, 30% were dedifferentiated, 10 % were round cell type and 10% had myxoid type of RPS. Conclusion: The CT features of retroperitoneal liposarcoma are pathognomonic and this helps in ruling out other retroperitoneal masses and the masses arising from the adjacent structures.
