| We have analyzed 44 cases of the ultrasonographic findings of pathologically provened retroperitoneal tumors.The results are as follows: 1. Among the tumor of the retroperitoneal structure in 44 cases, the most common organwas kidney in 26 cases(59%), the adrenal gland in 7 cases(16%) and the other retroperitoneal area in 11 cases(25%)2. 11 cases of hypernephroma revealed the localized or diffuse renal enlargement and lobulated contour containingthe internal echoes as follows: complex echo in 7 cases, hypoecho in 7 cases, hypoecho in 3 cases and hyperecho in1 case. The ultrasonographic findings of the Wilms' tumor in 6 cases revealed the localized or diffuse renalenlargement with smooth contour in 3 cases and lobulated contour 3 cases containing the internal echoes asfollows: hyperecho in 3 cases and complex echo in 3 cases. 3. The ultrasonographic findings of the adrenal tumorin 7 cases, the size was more than 3cm in diameter and showed the convex margin with round or ovoid shape in allcases. The internal echoes were as follows: complex echo in 4 cases and hypoecho in 3 cases. 4. Theultrasonographic findings of the metastatic tumor in retroperitoneal area in 7 cases revealed the well defined andnodular contour with hypo internal echo pattern in 6 cases and ill defined and irregular contour with complexinternal echo pattern in 1 case. 5. It was easy to define the anatomical localization of the mass lesions and tosee the mass character by ultrasonographic examination. |
