Uterus didelphys with unilateral distal vaginal agenesis and ipsilateral renal agenesis: common presentation of an unusual variation

Luther Adair 2nd et al. J Radiol Case Rep. 2011.

Abstract

Mullerian duct abnormalities are congenital malformations that are easily missed and can lead to incorrect diagnosis and unnecessary operative procedures. In this case, a young female presented with cyclic pelvic pain that continued after previous surgical resection of an ovarian cyst. Further investigation with clinical examinations and multimodality imaging demonstrated ipsilateral renal agenesis and a Class III Mullerian duct anomaly (MDA) requiring a second operative procedure. It is believed that this case is a variant of the described obstructed hemi-vagina with ipsilateral renal agenesis (OVIRA) anomaly as pathologically there was ipsilateral renal agenesis and complete vaginal agenesis in our case. It is imperative to have a high clinical suspicion of mullerian duct abnormalities when encountering a patient with other urogenital anomalies. This will decrease the amount of misdiagnoses, guide appropriate surgical intervention, and decrease the risk of future reproductive complications.

Keywords: didelphys; ipsilateral renal agenesis; unilateral; uterine; vaginal agenesis.

13 year old female with uterus didelphys, unilateral distal vaginal agenesis, and ipsilateral renal agenesis. Transabdominal ultrasound. Transverse sections demonstrated widely divergent uterine corpi, raising the index of suspicion for uterine duplication anomaly. Normal appearing uterus on the right (filled arrow). Distended endometrial cavity identified on the left (open arrow). Complex cyst superior the urinary bladder was initially presumed to be a complex left ovarian cyst (arrow head). (Protocol: 3.5 MHz curvilinear transducer (Phillips).

13 year old female with uterus didelphys, unilateral distal vaginal agenesis, and ipsilateral renal agenesis. Axial T2 noncontrast demonstrates a normal right uterine horn (long arrow). Distended lower uterine segment with blood products (short arrow). Distended tubular structure noted extending to the expected left adnexa superior to the distended left uterus, compatible with hematosalpinx (arrow head). (Protocol: 1.5 Tesla MRI (GE Signa Excite), TR/TE: 2800/80, 5mm slice thickness, non-contrast).

13 year old female with uterus didelphys, unilateral distal vaginal agenesis, and ipsilateral renal agenesis. Coronal long axis non-fat saturated FSE T2. After administration of sterile saline plus sterile ultrasound gel into the vaginal fornix via a small sterile catheter (arrowhead) high T2 signal extended from the vaginal fornix into a normal appearing cervix and uterine horn confirming patency on the right (filled arrow) and corresponding with a prior physical exam performed by the surgeon. Note blind-ending uterus (long arrow). Please note the lower uterine segment (open arrow). (Protocol: 1.5 Tesla MRI (GE Signa Excite), TR/TE: 4000/110, 5mm slice thickness, non-contrast).

13 year old female with uterus didelphys, unilateral distal vaginal agenesis, and ipsilateral renal agenesis. Coronal long axis non-fat saturated FSE T2. Left uterine horn and distended, blind-ending left lower uterine segment ended in intermediate signal tissue at the superior aspect of what appeared to be the vagina as noted on prior MRI (open arrow). Normal right uterine horn (filled arrow) and blind-ending uterus (long arrow). (Protocol: 1.5 Tesla MRI (GE Signa Excite), TR/TE: 4000/110, 5mm slice thickness, non-contrast).

Normal right ovary, fallopian tube, uterus, cervix, and vagina. Left uerine horn with normal left ovary, left hematosalpinx, hematometra, and blind-ending left uterine segment (open arrow). Note there is no left vagina or exocervix.
