Suture granulomas: sonography enables a correct preoperative diagnosis.

Abstract

The purpose of this study was to examine if suture granulomas display distinct sonographic signs and if these signs enable an accurate preoperative diagnosis. In a retrospective and prospective study, the sonographic findings of 22 consecutive suture granulomas were investigated and correlated with subsequent operative results. The sonographic appearance of various surgical sutures in a water bath was also investigated. Sonography was performed with commercially available 5- to 13-MHz linear transducers. The sonographic findings of the suture granulomas included hypoechoic lesions in all cases and hyperechoic double or single lines within the hypoechoic lesions in 20 of 22 cases. Sonography enabled the correct preoperative diagnosis for the investigating radiologists in 20 cases. The sonographic appearance of sutures in a water bath was that of hyperechoic double or single lines. The sonographic signs of suture granulomas (hyperechoic double or single lines within hypoechoic lesions) indicate the correct preoperative diagnosis in a high percentage of cases.
