Abstract
Varicocele, the most important identifiable pathological cause of male infertility, is rarely observed on the right side. In isolated cases of right-sided varicocele, the presence of retroperitoneal masses compressing the inferior vena cava should be considered by further investigation. The retroperitoneal masses that are detected tend to grow rapidly due to their location and may be very large at the time of diagnosis. Soft tissue sarcomas are the most common cause of retroperitoneal masses, while paragangliomas are rare causes. Retroperitoneal paragangliomas should be diagnosed via detection of symptoms caused by hormonal activity, observation of the compression effect of the mass, or incidentally during imaging studies. SIMILAR CASES PUBLISHED: This study presents the first case of retroperitoneal paraganglioma in a 41-year old man as isolated right-sided varicocele that has been described in the published reports.
