WS09‐07Ultrasound, Doppler and contrasts in metastases from gynecologic tumor

Abstract

The breast cancer metastases can be analyzed by ultrasound in ganglial and visceral organs. The detection of metastatic lymphonod in the axillar, cervical or supraclavicular regions and intrammamarian changes both the cancer staging and therapeutic planning. Benign lymphonode usually have an oval shape, hilum hyperechogenicity, narrow cortex and show hilar vascularization or radical central symmetric vascularization and absence of peripheral flow at Color Doppler. Malignant lymphonode are usually rounded hyporechoic, without hilar hyperechogenicity, and, in color Doppler, present multifocal aberrant vascularization, tortuous vessels or flow in the periphery. The most frequent visceral metastases of breast cancer are hepatic, the suprarenal glands and ovaries. About 86% of breast cancer hepatic metastases are hypoechoic. Ovarian cancer metastases can be detected mainly in pelvic tumors, peritonium tumors, glanglial, abdominal wall, hepatic and splenic metastases and ascites. Our study of 10 cases of splenic metastases of ovarian cancer has demonstrated six hyperechoic tumors, two hypoechoic and two tumors with necrosis. The use of color Doppler and Powerangio has demonstrated weak or moderate vascularization in glanglial and visceral metastases of gynecological tumors. The use of contrast (Levovist) has shown a more detailed vascular analysis by detecting vessels that were not identified in color Doppler and Powerangio without contrast.
