Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA), also known as Herlyn-Werner-Wunderlich syndrome, is a rare syndrome with. Herlyn-Werner-Wunderlich (HWW) syndrome, is a rare anomaly characterised by Müllerian duct anomalies (MDA) associated with mesonephric duct anomalies. Herlyn-Werner-Wunderlich (HWW) syndrome is a very rare congenital anomaly of the urogenital tract involving Müllerian ducts and Wolffian.

Obstructed hemivagina and ipsilateral renal anomaly OHVIRAalso known as Herlyn-Werner-Wunderlich uwnderlich, is a rare syndrome with only a few hundred reported cases described since Only a handful of these cases have been associated with pyocolpos. Symptoms usually present shortly after menarche when hematocolpos develops during menstruation resulting in dysmenorrhea and a pelvic mass.

The pelvic mass is the collection of blood products within the obstructed hemivagina. The first study in the diagnostic work-up is usually ultrasonography, which typically demonstrates a pelvic fluid collection which can simulate other disease processes thus confounding the diagnosis.

MRI findings of the pelvis reveal a didelphic uterus. Imaging of the abdomen reveals agenesis of the ipsilateral kidney. MRI is beneficial in characterizing the didelphic uterus and vaginal septum for pre-operative planning. Understanding the imaging findings, in conjunction with the clinical presentation, is critical for early diagnosis in attempting to prevent complications such as endometriosis or adhesions from chronic infections with subsequent syndroke.

We present an unusual case of a didelphic uterus with pyocolpos in an obstructed hemivagina and ipsilateral renal anomaly figure 1. Didelphic uterus with left hemivaginal obstruction LVhydrometrocolpos of the left uterine horn LU and ipsilateral renal agensis. Occasional ectopic ureter Ur insertion into the obstructed hemivagina can occur. A year-old Caucasian female presented to our institution with progressive painful distention of the lower abdomen.

It was not until recently that she began complaining of yellowish vaginal discharge. She denied fevers, chills, nausea, vomiting or diarrhea. However, she reported an ultrasound performed in a small military medical clinic in Samoa, prior to her arrival, revealed absence of her left kidney. The patient had reported overall good health.

She denied sexual activity or exposure to sexually transmitted diseases. She also denied any gynecological problems except for the recent cyclic abdominal pain and enlarging abdominal mass.

The patient reported normal menstruation beginning at 12—13 years of age. She denied any prior surgeries, use of medications or allergies. Family history was relevant for a paternal aunt with ovarian and cervical cancer and a mother with questionable cervical cancer. Physical exam was remarkable only for a palpable left pelvic mass, which measured 4. Speculum exam revealed a fluctuant intravaginal mass. A normal appearing right sided cervix was identified with yellowish vaginal discharge.

The external genitalia was normal. Furthermore, a urinalysis later demonstrated a urinary tract infection, which was subsequently treated with antibiotics. The patient was sent to radiology for further characterization. A pelvic ultrasound was performed revealing a 7 cm fluid collection with diffuse low level internal echoes, which appeared contiguous with the endocervix figure 2.

Subsequently, a MRI was performed to better characterize the pelvic anatomy and better identify the anatomic location of this pelvic fluid collection. A didelphic uterus was demonstrated. The right endometrial cavity appeared normal along with the right cervix.

The left endometrial cavity was moderately distended and contiguous with the obstructed hemivagina. The fluid in the obstructed left hemivagina measured 6. Imaging of both renal fossae confirmed the ultrasound findings of left renal agenesis figure 4.

Note the right uterine horn small arrow. The patient was subsequently sent to interventional radiology for drainage of the obstructed left hemivagina to alleviate her pain before surgical resection of the vaginal septum. A pigtail catheter was placed under ultrasound guidance. Purulent fluid was drained and sent to the lab for further evaluation. Aerobic cultures grew out staphylococcus aureus and agalactiae, while the anaerobic cultures grew out lactobacillus and prevotella bivia.

The pigtail catheter was left in place for 4 days at which time it was removed in the locked position in an attempt to prevent reaccumulation of fluid by lacerating the wall of the hemivagina Figure 5. This was done in an attempt to forgo the need for vaginoplasty. However, follow-up MRI 2 days after drain removal demonstrated re-accumulation of fluid in the left hemivagina Figure 4.

The patient subsequently underwent successful surgical resection of the vaginal septum.

There is a spectrum of uterine ysndrome anomalies that can occur during early development. Lateral fusion defects are the most common type of Mullerian duct abnormalities ranging from symmetric or asymmetric to obstructed or non-obstructed fusion anomalies.

This has ultimately wwerner to the classification scheme developed by the American Fertility Society, which describes the appearance of the uterus given the various fusion anomalies that can occur figure 6. The spectrum of fusion anomalies. A didelphic uterus with an obstructed hemivagina and ipsilateral renal agenesis OHVIRA is a rare eerner anomaly constituting 0.

Patients present with pelvic pain, worsening dysmenorrhea, and an associated pelvic mass [ 2 ].

There have only been a few case reports to date discussing the rare complication of pyocolpos in this entity. As in our case, most cases report a history of normal regular menstral periods up until there is an obstruction of the hemivagina resulting in abdominal distention and pelvic pain. Some patients occasionally present with urgency, frequency or vaginal discharge [ 3 ].

A didelphic uterus is suggestive of an embryologic arrest occurring during the 8th week of gestation which ultimately affects the Mullerian and Metanephric ducts [ 4 ]. The exact cause of this developmental defect is not known. However, if one of the Wolffian ducts is absent, the kidney and ureter on the ipsilateral side will fail to fuse at midline. This process may occur completely or incompletely.

If the failure to fuse is complete, then a uterus didelphys is formed. The Mullerian duct, on the side lacking the Wolffian duct, displaces itself laterally and cannot come into contact with the urogenital sinus in the center resulting in a blind sac, imperforate or obstructed vagina. However, the distal part of the vagina, originating from the urogenital sinus is not affected [ 4 ]. Each ureteric bud develops from the Wolffian duct which is ultimately responsible for the development of the kidney.

Occasionally an ectopically obstructed ureter inserts into the obstructed hemivagina on the side of the congenitally absent ipsilateral kidney figure 1 [ 3 ].

The ureteric bud grows dorsocranially into the metanephric blastema inducing differentiation of the metanephric nephrons. If the ureteric bud fails to either form or make contact with the metanephric blastema, the kidney on that side will fail to develop [ 4 ]. Although US can be used to diagnose this condition, MRI plays an important role in further characterizing the didelphic uterus, obstructed hemivagina, and ipsilateral renal agenesis.

Furthermore, MRI is superior to ultrasound by allowing for better characterization of anatomic relationships given its multiplanar capabilities and wider field of view, important for surgical planning. Delays in diagnosis have been attributed to lack of understanding of this condition by radiologists, gynecologists, and pediatricians.

Furthermore, regular menstruation in the context of an incomplete vaginal outlet obstruction and slow extension of hematocolpos have also been described as culprits to delayed diagnosis [ 3 ]. Delayed diagnosis can lead to complications that include endometriosis, adhesions, infertility and infectious complications arising from chronic cryptomenorrhoea [ 1 ].

The diagnosis of OHVIRA should be suspected in cases of women presenting with pelvic pain and a pelvic mass with ipsilateral renal agenesis. Systematic analysis of the literature suggests management of these cases to consist mainly of vaginoplasty with excision of the vaginal septum in order to prevent the long term complication of recurrent pyocolpos and infertility from chronic cryptomenorrhoea.

Those cases where an herlyj ureter uerlyn into the obstructed hemivagina, laproscopic surgical ligation vs surgical removal is advocated to prevent recurrent fluid accumulation in the obstructed hemivagina [ 3 ].

It could be argued that surgical excision might be better as there have been reported cases of malignant transformation occurring in the ectopic ureter [ 3 ]. OHVIRA obstructed hemivagina with ipsilateral renal agenesis with pyocolpos is a rare clinical presentation.
