阔韧带平滑肌瘤的影像诊断(附九例报告)

目的 研究阔韧带平没肌瘤的影像诊断。方法 回顾性总结９例经手术和病理证实为阔韧带平滑肌瘤的Ｂ超、ＣＴ及ＭＲＩ表现。结果 ９例Ｂ超检查表现为盆腔内、子宫外实性肿块，呈低回声灶，４例内有斑点状液性暗区或不均匀光点，５例显示包膜，７例边界清晰。８例ＣＴ检查７例表现为实性肿块，边界较清晰，平扫密度较均匀，与子宫肌密度相当或稍低；１例为混合密度灶，可见液化、坏死与囊变；８例增强扫描实性部分均见明显强化，４例

Imaging diagnosis of broad ligament leiomyoma (report of 9 cases )

Objective To study imaging diagnoses of the broad ligament leiomyoma Methods The findings of ultrasound, computed tomography and magnetic resonance imaging of 9 cases with broad ligament leiomyoma were retrospectively analyzed The diagnosis was proved by operation and pathology Results The findings of ultrasound were pelvic and extrauterine solid hypoechoic masses in all cases There were patchy fluid areas or inhomogeneous hyperechoic points in 4 case, capsule in 5 cases and clear margin in 7 cases Among 8 cases of CT examination, there were solid masses in 7 cases with clear border and homogeneous density similar to uterus muscles and mixed masses in 1 case on plain CT scan The masses were obviously enhanced on contrast enhanced CT scan There were inhomogeneous patchy and non enhanced areas in the tumor in 4 cases MR was obtained in 2 cases, which demonstrated masses with capsule and clear border These tumors had a signal of intermediate or slightly low intensity on T 1 weighted images, while on T 2 weighted images an intermediate signal intensity of the masses with patchy and stripe hyperintense areas were seen The masses were obviously enhanced with patchy non enhanced areas after intravenous Gd DTPA injection Conclusion The detection of a large, solid mass by ultrasound, CT or MR in extrauterine pelvis with capsule indicates broad ligament leiomyoma MR possesses good soft tissue resolution, multi direction imaging and the fat suppression technique which can demonstrate the capsule, inner structure of the tumor, and help establish the diagnoses
