Abstract:
Objective To explore the clinical diagnostic value of high frequency ultrasound on finger parenchyma tumor. Methods Twenty-two patients with finger parenchyma tumor were analyzed retrospectively by clinical and ultrasonographic characteristics including location, size, shape, echo, and color flow signals of tumors. Those findings were compared with pathological data after surgery. Results Out of 22 parenchyma tumor patients, tendosynovial giant cell tumor were present in 7 patients, fibrous tumor in 3 patients,glomus tumor in 5 patients, and ganglia in 7 patients. Differences between ultrasonographic appearances and pathologic features were found in parenchyma tumor. The tendosynovial giant cell tumors were demonstrated plentiful color flow signals and heterogeneous echoic mass without capsules. There was not found color flow signal but an intact membrane in tendosynovial fibrous tumors. Glomus tumors were hypoechoic with an intact membrane, abundant color Doppler signals, and Ⅲ level was classified by Alder. Ganglia were expressed in cystic structure. Conclusions Characteristic features of ultrasonographic appearance were found in different kind of parenchyma tumors. High frequency ultrasound is an effective method to diagnosis finger parenchyma tumor.
