To date, descriptions of pathologic conditions of the seminal vesicle in rabbits are scarce and limited to the laboratory animals in experimental conditions. The present article describes three cases of strangury, abdominal pain, and anorexia associated with seminal vesiculitis in pet rabbits. Three non-neutered male pet rabbits aged 3.6, 1.5, and 2.1 yrs were presented with strangury, abdominal pain, and anorexia. Seminal vesiculitis was diagnosed based on clinical signs and ultrasonography findings. Vesiculectomy was performed in two cases that presented strangury refractory to medical treatment, and diagnosis was confirmed by histopathology. In the third case, the patient received medical treatment, and a sequela in the form of lithiasis of the seminal vesicle was detected 3 yrs later. Plain radiographs were nearly unremarkable, and results from complete blood analysis and urinalysis were not specific in all three cases. Contrast radiography was performed in one case, showing a dilated seminal vesicle. Ultrasound and surgical biopsy seem to be the most sensitive techniques in the diagnosis of this pathology. Seminal vesiculitis must be included in the differential diagnosis of acute or chronic strangury in male pet rabbits.
