Three-Dimensional Technology to Diagnose Unilateral Cervical Atresia in Obstructive Hemivagina with Ipsilateral Renal Anomaly: A Case Report and Review of the Literature

Congenital atresia of the cervix in the setting of an obstructed hemivagina with ipsilateral renal anomaly (OHVIRA) is an unusual occurrence which is frequently missed by preoperative imaging modalities.A 14 year-old adolescent female presented to a tertiary-care facility with abdominal pain associated with a mass. Initial imaging with ultrasound and MRI (magnetic resonance imaging) suggested OHVIRA but a 3-D MRI also correctly identified unilateral cervical atresia on the obstructed left side.3-D MRI in the setting of OHVIRA was used successfully in this case to preoperatively identify cervical atresia and to guide preoperative surgical counseling and planning. The use of 3-D MRI for this purpose has never been described in the literature.
