侵蚀性葡萄胎的MRI诊断

目的 探讨侵蚀性葡萄胎的MRI表现及其诊断价值.资料与方法 回顾性分析8例经临床手术和病理证实的侵蚀性葡萄胎患者的MRI表现.结果 所有8例患者MRI表现为宫腔增大,肌层不均匀增厚,宫腔和肌层内可见长T1、长T2信号的囊性影和等信号结节影,外肌层和盆腔内可见大量的血管流空信号.5例宫腔和肌层内见斑点状、条片状高信号出血灶.6例双侧附件出现实性或囊性肿块.增强扫描表现为宫腔、肌层及附件病灶呈环形和结节状强化.结论 侵蚀性葡萄胎MRI表现具有特征性,有助于诊断.

Magnetic Resonance Imaging Findings of the Invasive Mole

Objective To investigate the magnetic resonance imaging (MRI) features in the diagnosis of the invasive mole. Materials and Methods MRI findings in eight patients with invasive mole confirmed by pathology were reviewed retrospectively. Results Enlargement of the uterine cavity and irregularly thickened myometrium were observed in all eight cases with long T1 and long T2 cystic lesions and iso-intense nodules in the uterine cavity and myometrium and signal void of vessels in the deep myometrium and pelvic cavity. Spotty and patchy high intense hemorrhagic lesions were found in 5 cases. Solid or cystic masses were found in bilateral adnexas in six patients. Gadolinium-enhanced T1-weighted imaging showed rim and nodular enhancement in all 8 cases. Conclusion The invasive mole displayed characteristic MRI findings, contributing to the diagnosis.
