Introduction
The report by McCarthy and coworkers (McCarthy et al. 2021) in this issue describes a case of vaginal septum with pyometra in a 10‐week‐old Westphalian filly foal. This is an interesting case report which evokes thought about the developmental abnormalities of the caudal female reproductive and urogenital tracts and their pathophysiology. Such anomalies are rare, reflected by the limited number of cases reported in the literature involving mares/fillies with uterine, cervical, vaginal and hymenal abnormalities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
