Objective To observe CT and MRI manifestations of uterine leiomyomatosis involving the inferior vena cava and the right cardiac cavity.Methods Eight patients with pathologically diagnosed uterine leiomyomatosis involving the inferior vena cava and right heart chamber were enrolled,and their preoperative CT and MRI data were analyzed retrospectively.Results CT and MRI images showed that the majority of the lesion floated in the vein or heart cavity and connected with the primary or recurrence lesions with moderate heterogeneous enhancement.When the right heart was involved,it looked like walking stick head or snakeheads.Dilated and tortuous blood vessels could be found around the primary or recurrent uterine leiomyomatosis,which was the specific feature of uterine leiomyomatosis.Conclusion CT and MRI can not only observe the range of uterine leiomyomatosis involving the inferior vena cava and the right cardiac cavity,but also detect the primary or recurrent pelvic diseases,therefore are important to the treatment and prognostic evaluation.
