Solid masses. A: Transverse sonogram showing enlarged right ovary (between +'s) with echogenic areas consistent with hemorrhage due to ovarian rupture. B: Same patient as in (A) showing intraperitoneal fluid representing blood from ruptured ovary. C: Longitudinal transabdominal sonogram (TAS) demonstrating solid mass (arrow) in cul-de-sac arising from torsed right ovary. D: Transverse TAS of same patient as in (C) showing that left ovary (straight arrow) is normal in size and adjacent to torsed right ovary (curved arrow). E: Interligamentous fibroid (*) appearing as solid pelvic mass. F: Myxomatous uterine tumor (large arrow) arising from uterine fundus (curved arrow). G: Same tumor as in (F). Ultrasound shows extent of tumor (*), which occupies entire abdomen. H: Transabdominal sonogram of predominantly solid undifferentiated ovarian neoplasm (arrow) containing a few cystic areas. I: Transabdominal sonogram of a solid pelvic mass with calcifications (arrow) in elderly patient. A cystadenofibroma with calcification was found at surgery. J: Longitudinal TAS of pelvic kidney (arrow). Pelvocalyceal system accounts for central echogenicity. K: Magnified transverse TAS showing solid left-adnexal mass (between +'s), which represented hemorrhagic corpus luteum cyst. L: Longitudinal TAS of solid teratoma with calcified areas. M: Magnified TAS of solid mass (between +'s) representing hemorrhagic corpus luteum cyst. N, O: Sagittal (N) and transverse (O) transabdominal sonograms showing a 5 × 7 cm solid mass associated with ascites. This was ovarian cancer. P: Transvaginal sonogram of large solid tumor representing a dysgerminoma. Q: Transvaginal sonogram of endometrioma showing "ground glass" texture arising from organized hemorrhage. R: Transvaginal sonogram of pelvic hematoma status, post-hysterectomy. The hematoma contains areas of different degrees of organization accounting for its irregular internal texture.
