“…Pre-operative ultrasound imaging may not reliably detect retroperitoneal cysts of Müllerian origin, as seen in our case where the cyst was not visualized on the preoperative ultrasound scan (Yacoub et al, 2021). Magnetic resonance imaging (MRI) provides a sophisticated method of distinguishing mullerian anomalies from one another, characterizing the degree of defect severity, and evaluating for concomitant urogenital anomalies noninvasively and without radiation exposure, with superior soft-tissue delineation and availability of advanced functional sequences (Udayakumar et al, 2023). MRI is also a commonly used tool for evaluation of pelvic malignancies.…”

Retroperitoneal cysts of Müllerian origin are rare and often discovered incidentally during surgical procedures or imaging studies. We present a case of a retroperitoneal cyst found during a total laparoscopic hysterectomy performed for myoma removal. A 40-year-old female presented with symptomatic myomas and underwent pre-operative evaluation, including pelvic ultrasound, which revealed no abnormalities apart from the myomas. A cyst was incidentally discovered in the retroperitoneal space during a total laparoscopic hysterectomy procedure. The cyst was excised and sent for histological examination, which confirmed its Müllerian origin. Retroperitoneal cysts of Müllerian origin are rare findings during TLH. This case report highlights the importance of thorough pre-operative evaluation and imaging studies and the significance of intraoperative awareness in identifying incidental findings. Further research is warranted to determine the optimal diagnostic imaging strategies for such cysts.

“…Therefore, MRI is a promising option among these methods. MRI has been successfully utilized in humans to detect developmental anomalies of MDs owing to its exceptional soft tissue resolution and accuracy (Udayakumar et al, 2023). Moreover, MRI has exhibited outstanding resolution, nearly equivalent to histology, for the imaging of mouse embryos (Turnbull and Mori, 2007).…”

Gamete-exporting organs of vertebrates: dazed and confused

Mature gametes are transported externally for fertilization. In vertebrates, the gonads are located within the coelom. Consequently, each species has specific organs for export, which often vary according to sex. In most vertebrates, sperm ducts and oviducts develop from the Wolffian and Müllerian ducts, respectively. However, exceptions exist. Both sexes of cyclostomes, as well as females of basal teleosts, lack genital ducts but possess genital pores. In teleosts of both sexes, genital ducts are formed through the posterior extensions of gonads. These structures appear to be independent of both Wolffian and Müllerian ducts. Furthermore, the development of Wolffian and Müllerian ducts differs significantly among various vertebrates. Are these gamete-exporting organs homologous or not? A question extensively debated around the turn of the 20th century but now largely overlooked. Recent research has revealed the indispensable role of Wnt4a in genital duct development in both sexes of teleosts: zebrafish and medaka. wnt4a is an ortholog of mammalian Wnt4, which has functions in Müllerian duct formation. These results suggest a potential homology between the mammalian Müllerian ducts and genital ducts in teleosts. To investigate the homology of gamete-exporting organs in vertebrates, more detailed descriptions of their development across vertebrates, using modern cellular and genetic tools, are needed. Therefore, this review summarizes existing knowledge and unresolved questions on the structure and development of gamete-exporting organs in diverse vertebrate groups. This also underscores the need for comprehensive studies, particularly on cyclostomes, cartilaginous fishes, basal ray-finned fishes, and teleosts.

In females, the paramesonephric (syn: Müllerian) duct gives rise to the uterine tubes, uterus, cervix, and part of the vagina. Segmental uterine aplasia resulting from a paramesonephric duct abnormality has been reported in a range of species including bovids, canids, felids, equids, camelids, and lagomorphs. Here we document segmental aplasia of the left paramesonephric duct in a New Zealand white rabbit. The proximal 70 mm of the left uterine tube was present and terminated in adipose tissue. A 10 × 2 × 1-mm tag of cream tissue was present and was composed of sheets of adipose tissue and streams of smooth muscle, but otherwise, there was no evidence of the left uterine horn, supporting a diagnosis of unilateral uterine aplasia (uterus unicornis) analogous to a human class II (unicornuate uterus) lesion of the “no horn” subtype. In addition, our case had a concurrent uterine tube fimbrial cyst, minor cysts in the left kidney, and mammary gland hyperplasia with secretory activity. We suggest the adoption of a uniform classification system specifically for lagomorph uterine anomalies. Large-scale multi-center studies documenting prevalence of such lesions would facilitate identification of trends in laterality and other factors.
