A 35 year old woman came with pain and swelling in the right thumb since two weeks
On ultrasonography of the right thumb, there is edematous thickening of the abductor pollicis longus and extensor pollicis brevis tendons. A pretendinous hypoechoic halo is there suggestive of subcutaneous edema.
De Quervain’s tenosynovitis is named after Fritz de Quervain (1868–1940), a renowned Swiss surgeon who first identified and described the condition in 1895.
