Front. Vet. Sci. 6:145. doi: 10.3389/fvets.2019.00145http://hdl.handle.net/10919/91954This case documents a rare set of congenital anomalies that resulted in an atypical cystic lesion in the cranial vagina of a queen. A discrete cystic lesion was identified in an 8 year old intact female domestic shorthair cat presenting for routine ovariohysterectomy. Morphological, radiographic, and histopathological findings were consistent with segmental aplasia of the uterus, cervix, and vagina resulting in a blind dilation of the cranial vagina. Segmental vaginal aplasia in combination with the failed canalization of the cervix resulted in a blind portion of the cranial vagina, in which normal secretions collected and became inspissated. This formed a discrete cystic structure. This case represents a novel combination and clinical presentation of segmental aplasia in the cat, involving both the uterus and cranial vagina. Ovariohysterectomy was performed for sterilization and a partial vaginectomy was performed to remove the cystic lesion in its entirety.6 pagesapplication/pdfenCreative Commons Attribution 4.0 Internationalsegmental aplasiauteruscervixvaginavaginal massdisorder of sexual developmentatresiacatArticle - Refereedhttps://doi.org/10.3389/fvets.2019.001456
