Abstract
Recently, the ultrasonic wave test has been rapidly employed in the various clinical fields and highly evaluated clinically. We employed the ultrasonic wave test for 5 cases with tumor in the soft parts and the results observed were as follows, ; The cases were smooth membrane sarcoma on right forearm region in a 18-year-old female, round cell sarcoma on right femoral region in a 18-year-old male, ganglion on left forearm in a 36-year-old female, hematoma on right forearm region due to hemophilia in a 13-year-old male and hematoma on right femoral region in a 52-year-old male. The ultrasonic wave test was effective for 2 cases with malignalt tumor from the viewpoint of the presence or absence of tunic involucre, differentiation of massive type or cystic type, and diagnosis of tumorous region, but the detail tests such as presence or absence of infiltration, types of tumor were difficult. The diagnostic method by ultrasonic waves was effective for hematoma, and especially useful for the observation of its chronological changes in hemophilia. The diagnostic method by ultrasonic waves had defects such as problem of artifact or unfavorable propagation by ultrasonic waves in bone in the orthopedic field, but it was considered that this method is useful because there were many advantages such as easy manipulation without pain, low cost, etc.
