Obstructed hemivagina with ipsilateral renal and urinary tract anomaly presenting as an unusual cause of acute abdomen: a radiologic perspective.

Obstructed hemivagina with ipsilateral renal anomaly (OHVIRA) is a rare congenital genitourinary defect with a triad of unilateral vaginal obstruction, uterine anomaly and ipsilateral renal agenesis. This paper reports an unusual presentation of OHVIRA, with our patient experiencing severe abdominal pain from a left tubo-ovarian abscess that is contralateral to the side of the vaginal outflow obstruction. Another reportable finding is our patient's rare association of a trifid ureter that fuses distally before inserting ectopically in her vaginal canal. Lastly, this case report also emphasises the importance of radiologists' expertise in suspecting the diagnosis early on and in contributing to the preoperative evaluation of patients with OHVIRA, thereby providing adequate management for these patients.
