Abstract

Vulvar and vaginal lesions representing a wide spectrum of diseases in female lower genital tract diseases make up a small part of all gynecological etiologies. Many of them are rare etiologies and are reported in case-reports studies. Translabial and transperineal ultrasound are modalities of choice for the first evaluation of perineal lesions. MRI is usually performed to determine the etiology of the lesions and stage. Benign lesions of the vulva and vagina usually manifest as simple cystic (vestibular cyst or endometrioma) or solid lesions (leiomyoma or angiofibroblastoma), while malignancies usually appear as large, solid masses and fill into both vaginal and perineal area. Post-contrast images play an important role in establishing a differential diagnosis, however, some benign lesions can also exhibit a vivid enhancement. Knowledge about radiologic-associated pathological manifestations may aid clinicians in better understanding these pathologies, especially for some rare lesions, and making a proper diagnosis before invasive procedures.

外阴和阴道常见和不常见病变的磁共振成像:与病理结果的相关性。
外阴和阴道病变代表了女性下生殖道疾病的广泛范围,占所有妇科病因的一小部分。其中许多是罕见的病因,并在病例报告研究中报告。经唇超声和经会阴超声是首次评估会阴病变的首选方式。MRI通常用于确定病变的病因和分期。外阴和阴道的良性病变通常表现为单纯的囊性病变(前庭囊肿或子宫内膜瘤)或实性病变(平滑肌瘤或血管成纤维细胞瘤),而恶性病变通常表现为较大的实性肿块,并填充阴道和会阴区。对比后图像在鉴别诊断中起着重要的作用,然而,一些良性病变也可以表现出生动的增强。了解影像学相关的病理表现可以帮助临床医生更好地理解这些病理,特别是一些罕见的病变,并在侵入性手术前做出正确的诊断。
