Ultrasonographic appearance of metastatic non-gynecological pelvic tumors.

OBJECTIVE: To describe the ultrasound (sonomorphologic and vascular) characteristics of metastatic non-gynecological pelvic tumors, and to identify ultrasound characteristics typical of the most common non-gynecological pelvic tumors. METHODS: In 92 patients with a pelvic mass who had undergone ultrasound examination with subsequent surgery or tru-cut biopsy revealing a metastatic non-gynecological tumor origin, we analyzed retrospectively the sonomorphologic and vascular parameters. All parameters were evaluated for the whole group of non-gynecological tumors as well as separately for each specific tumor type. The findings were compared with those from 100 women with epithelial ovarian cancer. RESULTS: We found that CA 125, size of tumor, echogenicity, homogeneity of solid portion, mobility, and presence of ovarian crescent sign, parenchymal metastases and suspicious necrosis were individual statistically significant discriminators (P < 0.01) between the metastatic non-gynecological tumor group and the epithelial ovarian cancer group. CONCLUSIONS: Metastatic non-gynecological tumors in the pelvis have a significantly different sonomorphologic pattern compared with primary epithelial ovarian cancer. This pattern is dependent on the primary origin of the tumor. Doppler parameters, however, cannot differentiate between primary ovarian cancer and metastatic non-gynecological tumors.
