title: Acute suppurative tenosynovitis of the hand: diagnosis with US.
abstract: The sonographic findings in seven patients with surgically proved acute tenosynovitis of the hand (bacterial in six cases, of presumed viral origin in one) were reviewed. In the six patients with bacterial tenosynovitis the affected flexor tendon was larger than that of the contralateral normal digit. In five patients hypoechoic areas were identified surrounding the flexor tendon that proved to be pus at surgery. Sonography failed to depict a small amount of pus in the tendon sheath in one patient. The affected tendon of the single patient with tenosynovitis thought to be of viral origin was normal in size, but a focal tendon sheath fluid collection was detected that proved to be sterile at surgery. Sonography appears to be a useful imaging technique in the early diagnosis of acute suppurative tenosynovitis of the hand.
