Percutaneous Ultrasonographic examinations of perianal region were performed on 110 patients with clinical diagnosis of anorectal abscess. The characteristic ultrasonographic image of anorectal abscesses was a cystic pattern with smooth margin associated and reinforced posterior echo. According to ultrasonograms, anorectal abscesses were classified into four patterns ; 1) superficial type (S type) 51.8 %, 2) parietal type (P type) 13.6 %, 3) deep type (D type) 20.9 %, and 4) mixed types. The ultrasonographic diagnosis concerning the presence and site of abscesses and operative findings agreed in 97.2 % of the patients. <BR>Perianal ultrasonographic examination was a non invasive and accurate method in the diagnosis of anorectal abscess. <BR>It was also useful because it was capable to diagnose and locate the deep abscesses which were difficult to find on palpation.
