Abstract

Purpose: Congenital anomalies of seminal vesicle (SV) are rare but this entity is the most common cause of post- testicular obstruction of male infertility. Among the diagnosis modalities, magnetic resonance imaging (MRI) is considered as safe, objective and most efficacy in the evaluation of congenital anomalies of SV. Material and method: Descriptive study in the male patient group who were suspected male infertility in Hanoi Medical University Hospital from 2017 to 2019 and from 2020 to 2022, underwent a seminal vesical MRI 1.5 Tesla with high- resolution T2W sagittal, coronal, axial, 3D T2WFS and T1WFS. Results: Eighteen (18) patients were diagnosed as congenital anomalies of seminal vesicle in this study. Among them, 4 patients with bilateral agenesis, 3 patients with unilateral agenesis only, 2 patients with unilateral agenesis and contralateral hypoplasia, 6 patients with unilateral hypoplasia, 1 patient with bilateral SV cyst, 2 patients with SV dilatation. All patients with SV agenesis and/or hypoplasia were azospermia in the sperm count. The patients with SV hypoplasia and/or cyst were not associated with renal agenesis or hypoplasia. Conclusion: Because of non radiation, excellent soft tissu resolution, objective viewing and reporting, magnetic resonance imaging is the modality of choice to evaluate the congeninal anomalies of seminal vesical.
