   Abstract 

Herlyn-Werner-Wunderlich syndrome (HWWS), characterized by uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis, is an uncommon combined Mullerian and mesonephric duct anomaly, and its presentation in adulthood is even rarer. We report here a 22-year-old female presenting with primary infertility where magnetic resonance imaging (MRI) suggested the diagnosis of HWWS with endometriosis. In a patient of infertility with endometriosis and unilateral renal agenesis, diagnosis of HWWS should be suspected and MRI is the investigation of choice for such anomalies.

   Introduction Top


Herlyn-Werner-Wunderlich syndrome (HWWS) is often a misdiagnosed entity and high index of suspicion is required in patients with Mullerian and mesonephric duct anomalies. It usually presents at puberty with pelvic pain, but rarely can present in neonates or in adulthood in the form of pyometra, ischiorectal swelling, urinary obstruction, and primary infertility. [1],[2],[3],[4] Since this condition can be treated by vaginal septum excision, and delay in diagnosis may worsen the associated endometriosis, [5] early diagnosis is beneficial. Magnetic resonance imaging (MRI) is the modality of choice for the diagnosis of HWWS and other such anomalies because of better anatomic delineation of pelvic structures and higher sensitivity for blood products.


   Case Report Top


A 22-year-old female, cohabiting with her husband for last 3 years, was evaluated for primary infertility in a private hospital. She attained menarche at the age of 13 years and had a normal menstrual history with no complaints of excessive dysmenorrhoea, dyspareunia, or vaginal discharge. Routine hematological laboratory tests were normal. An abdominal USG and computed tomography (CT) were performed, which revealed absent left kidney, a bicornuate uterus, bilateral cystic adnexal lesions, and left hydrosalpinx. She was taken up for laparotomy and underwent left ovarian cystectomy and adhesiolysis. Histopathology from the left adnexal lesion showed endometriotic cysts and aspirated pelvic fluid showed hemosiderin-laden macrophages. Postoperatively, she was kept on medical management for endometriosis.

She did not resume her menses for 3 months post-surgery and urine pregnancy test was negative, following which she was referred to our institute for further evaluation. MRI examination of the pelvis was performed to assess the current status of endometriosis. MRI revealed two separate uterine cavities, cervices, and vaginas, suggestive of uterus didelphys [Figure 1], [Figure 2] and [Figure 3]. The right uterine cavity, cervix, and vagina were normal. The left uterine cavity and cervical canal were dilated and filled with fluid which was hyperintense on both T1W and T2W MRI [Figure 1] and [Figure 2] with few T2-hypointense areas [Figure 4] suggesting blood products. Left hemivagina was dilated [Figure 1], [Figure 2], and [Figure 4] with blood products within, implicating the presence of an obstructing left vaginal septum. Multiloculated left adnexal cystic lesions with blood products were seen suggestive of endometriotic cysts [Figure 5]. In addition, a tubular structure was noted in left adnexal location extending laterally from left uterine cornu with hemorrhagic fluid within, indicative of left hematosalpinx. Right ovary was normal. In addition, there was absent left kidney [Figure 6] with loculated hemorrhagic fluid collections in bilateral paracolic gutters, suggestive of peritoneal endometriosis [Figure 7].

Hence, a diagnosis of uterus didelphys with left hematometra, hematosalpinx, hematocolpos, and left hemivaginal obstruction with adnexal and peritoneal endometriosis was made. Considering that she also had absent left kidney, a final diagnosis of HWWS or obstructed hemivagina ipsilateral renal anomaly (OHVIRA) syndrome was made. Since the patient had already undergone recent laparotomy, no further surgery was immediately performed. She has been kept on short-term conservative management with oral contraceptives to suppress menstruation and laparoscopic vaginal septal excision has been planned after 3 months.


   Discussion Top


The most frequently used system for classification of Mullerian duct anomalies (MDAs) was proposed by Buttram and Gibbons, which classifies them into six categories [6] [Table 1].

HWWS is a combination of Type III Mullerian anomaly with mesonephric duct anomaly with vaginal septum. The classic renal manifestation of OHVIRA syndrome is ipsilateral renal agenesis, but reports of duplicated kidneys, dysplastic kidneys, [7] rectovesical bands, [8] or crossed fused ectopia [9] have also been described. Uterus didelphys with obstructed hemivagina is due to lateral non-fusion of the Mullerian ducts with asymmetric obstruction, and it is almost always associated with renal agenesis ipsilateral to the side of obstruction. [7] An important point to note in patients with HWWS is that renal agenesis is located ipsilateral to the dilated uterine cavity. On the other hand, in case of unicornuate uteri, the renal anomalies are ipsilateral to the rudimentary or absent uterine horn. [10] Embryopathogenesis of HWWS can be temporally located around 8 weeks of gestation, simultaneously affecting both Mullerian and metanephric ducts. [11]

Haddad et al. studied the associations of a blind hemivagina in 42 patients and found that it was associated with renal agenesis in all but one patient. In addition, blind hemivagina with ipsilateral agenesis was generally associated with uterus didelphys; however, rare cases of septate uterus were also found. [12]

Patients of endometriosis must be evaluated for any obstructive Mullerian lesion, [13] and presence of concomitant unilateral renal agenesis should indicate a suspicion for HWWS. Patients of HWWS usually have normal menstruation and may or may not complain of dysmenorrhoea, explaining the delay in diagnosis in adults. [14] Endometriosis is a frequent complication of this syndrome. This is because of obstructed outflow to part of the menstrual blood, which collects in obstructed Mullerian derivatives, leading to hematometra, hematosalpinx, and peritoneal endometriosis.

When suspecting a genitourinary anomaly, an initial screening ultrasound should be followed by MRI rather than CT, since the later involves radiation exposure and many questions remain unanswered because of its limited soft-tissue resolution. Considering the vast differential in uterovaginal anomalies, precise anatomical delineation of the uterus, tubes, cervix, and vagina is essential. Status of these reproductive organs and extent of endometriosis, pelvic inflammation, and adhesions can be well evaluated with MRI. [9] Laparoscopy remains the gold standard diagnostic modality with the additional advantages of therapeutic drainage of hematocolpos/hematometra, vaginal septectomy, and marsupialization. [15],[16]

Laparoscopic vaginal septum excision is the treatment of choice for HWWS. A successful pregnancy is achieved eventually in 87% patients, while 23% have the risk of abortions. [14]
