Seminal vesiculitis in golden hamsters (Mesocricetus auratus): two cases (2022)

Background

Seminal vesiculitis is a disease characterized by inflammation of the seminal vesicles. It has been reported in stallions, bulls, rams, boars, rabbits, mice, and rats but has not been reported in golden hamsters.

Methods

Golden hamsters (Mesocricetus auratus) with seminal vesiculitis diagnosed by histopathologic examination in a private animal hospital between February and December 2022 were eligible for inclusion.

Results

Two golden hamsters were included in the study. Both patients presented with lethargy and hematuria. Ultrasonographic examination of the seminal vesicles showed less distinct lobulation, wall thickening, and hyperechoic fluid in 1 case. One patient was treated with trimethoprim-sulfamethoxazole. The hamster died 11 days after presentation. The other patient was treated with a seminal vesiculectomy and was euthanized 66 days after surgery due to congestive heart failure and a left atrial mass. Histopathologic examination of seminal vesicles from both patients showed dilation, transmural necrosis, and inflammation.

Conclusions and clinical relevance

Seminal vesiculitis should be considered as a differential in male golden hamsters with hematuria. In the cases presented here, ultrasonography was useful to formulate a diagnostic suspicion. Treatment options require further investigation.
