Typical ultrasound picture of malignant testicular tumors is to increase its size, irregular shape of the tumor node, clear irregular contours, chaotic internal structure, the low intensity of the reflection. Malignant tumors of the genital organs of girls in 86% of cases are localized in the ovaries, 10% – in the moisture – deprivation and cervix, 3% – in the body of the uterus.
In rare cases, the tumor is localized in the outer opening of the urethra and vulva. On morphological characteristics are most common Hermine – gene ovarian tumors (80%) and sex cord stromal tumors (13%). Epithelial tumors (ovarian cancer) are not characteristic of childhood and account for 7%. Ultrasound picture of ovarian tumors characterized by the presence of the tumor site with clear smooth contours of the inhomogeneous structure, with zones without reflections, alternating with areas of parenchymal density. In most cases, the tumor is larger, performs the pelvis and lower abdomen, causing deformation and displacement of adjacent organs and tissues.
Tumors of the uterus and vagina are defined as nodes in parenchymal density. Besides malignant tumors of the abdominal cavity, retroperitoneal, pelvic cavity in pediatric practice, there are benign tumors, which tend to very rapid growth and can quickly mechanized. Terms of malignancy in these formations are very diverse, so the identification of cysts root of the mesentery, dermoid cysts, teratoma requires the active surgical intervention. Rare forms of solid tumors include abdominal mesothelioma – a malignant lesion of the peritoneum. The special features of this tumor include rapid development, significant size, rapid metastasis, marked ascites.
