Diagnosis of congenital oblique vaginal septum syndrome: A case report and literature review

Introduction: This report details a case of Type I oblique vaginal septum syndrome (OVSS), highlighting its complexity as a congenital uterine malformation.

Case presentation: A 12-year-old girl presented with severe lower abdominal pain coinciding with her first menstrual period. Ultrasound revealed a septate uterus and an oblique vaginal septum, prompting an emergency hysteroscopic procedure that confirmed the diagnosis of Type I OVSS.

Discussion: OVSS is a rare urogenital anomaly often diagnosed during adolescence. Common symptoms include abdominal pain, abdominal masses, and irregular vaginal bleeding. Due to its atypical presentation, OVSS is frequently misdiagnosed. Early surgical intervention is crucial to relieve pain and restore normal uterine morphology.

Conclusion: Diagnosing OVSS can be challenging, but early detection is vital to prevent complications such as retrograde menstruation and long-term issues.
