【摘要】 目的探讨苗勒管囊肿的CT和MRI表现,提高对该病的认识。方法收集经手术病理证实的苗勒管囊肿8例,回顾性分析其CT和MRI表现。结果 8例苗勒管囊肿中,其中1例位于右下腹部,呈类圆形肿块影,信号不均匀,T1WI肿块外周以等、稍高信号为主,中心呈高信号,T2WI外周呈明显高信号,中心为较高信号,增强未见强化;其余7例均位于前列腺后正中线,呈倒置的水滴状或椭圆形,6例T1WI呈低信号,T2WI呈高信号,1例CT表现为不规则囊性低密度影,内见条状纤细分隔,增强扫描均未见强化。结论根据苗勒管囊肿的CT和MRI表现及发病部位特点,可以在术前对苗勒管囊肿做出正确诊断。MRI较CT能提供更准确的信息,在本病的影像诊断中具有无可替代的作用。更多还原

【Abstract】 Objective To discuss the CT and MRI findings of Mullerian duct cyst and improve the recognition of this disease. Methods The CT and MRI findings of 8 cases with Mullerian duct cysts which proved by operation and pathology were retrospectively analyzed. Results One of the 8 cases was located in the right lower abdomen,which was a round-like mass with heterogeneous signal.The peripheral area of the mass showed isointesity signal or slightly high signal on T1WI and obvious high signal on T2WI,and the center showed high signal both on T1WI and T2WI.It had no enhancement. Other 7 cases were located in the midline behind prostate, which were inversion of water droplets or elliptic.6 cases showed low signal on T1WI and high signal on T2WI.The other one showed irregular cyst with low density on CT, in which could see slender septation.All the 7 cases had no enhancement. Conclusion According to the CT and MRI findings of Mullerian duct cyst and the location,can make correct diagnosis before operation.MRI can provide more accurate information than CT,and it had a irreplaceable role in the imaging diagnosis of the disease.更多还原
