Oblique Cervical Septum with Complete Uterine Septum: Diagnosis and Treatment of a Rare Case

BACKGROUND: Müllerian anomalies take many forms of manifestation. The oblique cervical septum with a complete uterine septum (OCSCUS), as a rare form of Müllerian anomaly, has never been reported in the literature. CASE: A 10-year-old female adolescent presented with progressive abdominal pain after the onset of menarche was diagnosed as OCSCUS using magnetic resonance imaging and treated with hysteroscopic dissection of the uterine part of the septum. SUMMARY AND CONCLUSION: Greater awareness of the OCSCUS will lead to earlier detection and is the key to alleviating patient suffering and avoiding potentially severe complications, such as endometriosis and infertility. For the treatment of OCSCUS, hysteroscopic dissection of the uterine part of the septum is a minimally invasive treatment choice with low surgical risk.
