Abstract

Purpose. The aim of this study was to review the incidence and type of seminal vesicle (SV) masses discovered during transrectal sonography (TRUS) of the prostate. Methods. Patients were a consecutive series of men referred for TRUS of the prostate because of lower urinary tract symptoms or elevated prostate-specific antigen levels, who were found on TRUS to have SV masses. Patients with prostate cancer involving the SVs were excluded. Cystic lesions were sampled by fine-needle aspiration and solid lesions by core biopsy, all under sonographic guidance. Results. Of the 450 patients who underwent TRUS between January 1997 and December 2001, 10 (2%) were found to have SV masses; 5 masses were cystic and 5 were solid. Cytologic evaluation of aspirated specimens revealed benign findings in all 5 cysts. Four of the 5 patients with solid SV masses had chronic schistosomiasis, and the mass in the fifth patient was a metastatic deposit from a renal cell carcinoma. Conclusions. SV masses may be responsible for lower urinary tract symptoms in a small fraction of cases. A cystic mass is presumptively benign, whereas a solid lesion has a small probability of being malignant, especially if the patient has a primary neoplasm elsewhere. Schistosomiasis should always be considered when making a differential diagnosis in patients who live in areas where infestation is endemic.
