An Atypical Cause of Primary Amenorrhea: A Case Report of Rare Vaginal Agenesis

Abstract

Vaginal agenesis is part of a group of anomalies, referred to as Mullerian anomalies due to their embryologic origin, in which there is a congenital absence of the vagina. We present a unique case in which a 20-year-old female presented to the Emergency Department with cyclical abdominal pain and primary amenorrhea. The original assessment showed a probable imperforate hymen; however, it was later found that she likely had vaginal agenesis. Vaginal agenesis is a rare disease, but it is prevalent enough that it should be kept at the forefront of the differential diagnosis in a woman with primary amenorrhea and recurring pain. We also highlight the importance of patient education in general, but categorically to sexual health.
