To document the frequency of epididymal and testicular abnormalities in asymptomatic men, scrotal sonography was performed on 75 men ranging in age from 10 to 84 years. Epididymal cysts larger than 3 mm in size were found in 23% of the patients, hydroceles in 23%, varicoceles (tortuous vessels ×3 mm in diameter) in 11%, testicular cysts in 4%, atrophy in 3%, and calcifications in 3%. The high prevalence of these findings can complicate the interpretation of sonograms of the symptomatic scrotum.
