Abstract:
Objective To recognize the CT manifestations of benign metastasizing leiomyoma (BML).Methods Four cases of BML proved by pathology were retrospectively analysed.Among these, 2 cases were pulmonary BML,1 ease was leiomyomatosis peritonealis diseminata(LPD),and 1 case was combined with pulmonary BML and LPD.All of them were female,and had a history of hysterectomy,the average age were 45.The CT findings of them were analyzed.Results The CT of pulmonary BML in three cases showed multiple rounded,well-defined discrete nodules,0.2—2.0cm in diameter,random distribution,and no calcification in the nodules.No hilum or mediastinum lymphadenopathy,and no pleural effusion.There were no enhancement after intravenous contrast examination.The CT findings of LPD in two cases were many masses around the vena cava,abdominal aorta and/or iliac artery.The masses were 4— 5cm in diameter with smooth margin and homogeneous density.No lymph node or ascites were found.One case who got intravenous contrast enhanced CT scan showed significant enhancement of the lesions;another case who got PET CT study showed no significant tracer concentration.Conclusion When multiple metastasizing nodular lesions with sharp margin and homogeneous density were found in the lungs or abdomen,they should be considered the possibility of BML in women with hysterectomy history.
