Analysis of ultrasonographic misdiagnosis of intravenous leiomyomatosis

Objective To observe the ultrasonographic features of intravenous leiomyomatosis(IVL).Methods Ultrasonographic features,pathological results and the clinical manifestations of 7 patients with IVLs were analyzed retrospectively,and the causes of misdiagnosis were discussed as well.Results The median age of 7 IVL patients was 40 years old.Five patients underwent previously hysterectomy due to probable diagnosis of leiomyoma with the mean recurrent time of 13.8 months.Three lesions extended into the right atrium,3 involved the inferior venous cava and 1 was confined in the pelvis venous.Ultrasonographic findings of IVL included uterine solid lesions with intravascular disease,solid occupied lesions in the pelvis with intravascular disease after hysterectomy,solid occupied lesions in the pelvis,large abdominal vessels and cardiac chambes with intravascular disease after hysterectomy.The main misdiagnosis cause was that IVL had similar ultrasonographic features with hysteromyoma,and intravascular lesions of IVL was hard to detect in the early stage.Conclusion Color Doppler ultrasonography is a valuable imaging mortality for detection and follow-up of IVL.
