Ultrasonography and computerized tomography (CT) imaging demonstrated soft tissue density mass lesions in the lower ureter. The mass was completely excised and retroperitoneal lymphadenectomy was done with the open approach and was verified as a primary leiomyosarcoma by post-surgical histopathological examination. The patient was alive without recurrence, lymphadenopathy and other complications above 18 months. We report the first case of primary leiomyosarcoma in infundibulopelvic ligament.
