The magnetic resonance imaging (MRI) and computed tomography (CT) appearance of 18 paravaginal cysts was reviewed. On MRI, serious cysts were hypointense on T1-weighted and hyperintense on T2-weighted images. Cysts presumed to contain proteinaceous material were hyperintense on T1-weighted and T2-weighted sequences while hemorrhagic cysts exhibited varying stages of hemorrhage. On CT, a high attenuation cyst was presumed to contain proteinaceous material or hemorrhage. MRI and CT examination may reveal paravaginal cysts; their varied appearance must be recognized to avoid confusion with other lesions.
回顾了18例阴道旁囊肿的磁共振成像（MRI）和计算机断层扫描（CT）表现。在MRI上，单纯囊肿在T1加权像上呈低信号，在T2加权像上呈高信号。推测含有蛋白质物质的囊肿在T1加权和T2加权序列上均呈高信号，而出血性囊肿表现出不同阶段的出血。在CT上，高密度囊肿推测含有蛋白质物质或出血。MRI和CT检查可发现阴道旁囊肿；必须认识到其多样的表现，以避免与其他病变混淆。
