Internal High Echoes Can Suggest the Possible Resection of Ovarian Vein Leiomyosarcoma: A Case Report

Year: 2025

Type: article

Abstract: Introduction: Leiomyosarcomas of ovarian veins often affect the IVC, the duodenum, and kidneys. Therefore, the resectability of the leiomyosarcomas highly depends on the presence or extent of their invasion to the surrounding organs. Case Presentation: A 55-year-old woman with a retroperitoneal mass on CT was referred to our hospital. CT and MRI showed a lobulated large mass with broad contact with the duodenum. EUS showed focal internal high echoes in the tumor areas adjacent to the duodenum. After obtaining the pathological diagnosis of leiomyosarcoma, the tumor was successfully removed without duodenum resection. Post-operative pathological findings confirmed the absence of direct leiomyosarcoma invasion to the duodenum and the sparse atypical cells with edematous background in the high internal echo areas. Conclusions: Surgeons should note that internal high echoes in the tumor areas adjacent to the duodenum can be an important predictor of possible resection of the retroperitoneal tumors.
