ABSTRACT
Introduction Mullerian anomalies arise because of aberrant embryogenesis and a longitudinal vaginal septum (LVS) is a failure of resorption of the distal Mullerian canal. A 26-year-old Material and methods pregnant lady with full-term gestation presented to our rural hospital in labour. Her physical examination was normal except for a partial longitudinal vaginal septum that she had in the proximal vagina distinct from the cervix extending from the 12 O clock position of the anterior vaginal wall to 6 O clock of the posterior vaginal wall along with a bulge felt in the posterior fornix. An emergency lower segment caesarean section was performed for possible fetal distress and a right ovarian mass was encountered which was removed along with the resection of the partial longitudinal vaginal septum. Her postoperative period was uneventful and the histopathology report of the ovarian mass turned out as a mature cystic teratoma. A partial Conclusion longitudinal vaginal septum can be easily resected during labour if it hasn't been diagnosed before. This is one of the ?rst cases reported where a partial LVS along with an ovarian mass was reported and managed successfully by resection
