Fetal magnetic resonance imaging is a useful modality for prenatal diagnosis of obstructed hemivagina and ipsilateral renal anomaly syndrome

摘要

The authors report the first case of prenatal fetal MRI diagnosis of unilateral hydrocolpos, uterus didelphys, and ipsilateral renal agenesis in a case of obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome. A 33-year-old woman was referred to the present institution because of a fetal pelvic cyst. Detailed ultrasound revealed a female fetus with a retrovesical cyst and right renal agenesis. Fetal MRI confirmed unilateral hydrocolpos, uterus didelphys, and normal intestinal tract of the fetus. Fetal MRI is a useful modality for prenatal diagnosis of OHVIRA as a method of evaluating the pelvic structures and excluding other cloacal anomalies.
