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

Background: Congenital atresia of the cervix in the setting of an obstructed hemivagina with ipsilateral renal anomaly (OHVIRA) is an unusual occurrence that is frequently missed using preoperative imaging modalities.

Case: A 14-year-old female adolescent presented to a tertiary care facility with abdominal pain associated with a mass. Initial imaging with ultrasound and magnetic resonance suggested OHVIRA but 3-D magnetic resonance imaging (MRI) also correctly identified unilateral cervical atresia on the obstructed left side.
