Sclerosing stromal tumor (SST) is a rare benign ovarian neoplasm of stromal origin with less than 100 cases reported in the literature. Unlike the other stromal tumors, thecomas and fibromas, which tend to occur in the fifth and sixth decades, sclerosing stromal tumors predominantly affect females in the second and third decades. Computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound findings have been described, but have not been reported previously in the pediatric literature. We present a case of SST of the ovary in a 10-year-old premenarchal female, the youngest patient to our knowledge reported in the literature, and describe the ultrasound and CT findings with pathologic correlation

OBJECTIVE: Endometrial polyps are relatively common in all groups of women. More polyps are being diagnosed with the widespread use of transvaginal ultrasound scanning and sonohysterography. The reported incidence of malignancy is low. The potential benefit of a noninvasive technique to distinguish benign from malignant polyps is obvious. This study was undertaken to evaluate endometrial polyps by color flow Doppler ultrasound scanning and histopathologic examination. STUDY DESIGN: This was an observational study of patients with an endometrial polyp on sonohysterography who underwent interrogation of their polyp with color Doppler ultrasound scanning and subsequently polypectomy. Polyp volume, resistive index, pulsatility index, indication for scan (bleeding vs incidental), and patient age were correlated with histopathologic type of the polyp (nonfunctional, proliferative, secretory, hyperplastic, or malignant). RESULTS: Of 61 patients studied, 42 patients (68.9%) were scanned for abnormal bleeding, and 19 patients (31.1%) had their polyps discovered incidentally. There were no statistically significant differences between histologic categories and the resistive index, pulsatility index, or size of the polyp. The age of patients with nonfunctional polyps was significantly greater than any other group (P <.001). Ninety-four percent of the functional polyps were discovered because of abnormal bleeding; 38% of the nonfunctional polyps were discovered incidentally (P <.001). CONCLUSION: The data suggest that the objective assessment of blood flow impedance (resistive index, pulsatility index) in endometrial polyps and the size of these polyps cannot replace surgical removal and pathologic evaluation to predict histologic type. Patients with nonfunctional polyps were older and less likely to have vaginal bleeding
