Answer

Transvaginal sonography (TVS) is by far the best primary modality for imaging pelvic structures. This may allow for delineation between ovarian, tubal, uterine, and other pelvic masses. If an adnexal mass is identified, the presence of cystic or solid components should be noted and remarks on the internal architecture of cystic structures (eg, septations, excrescences) should be made. Free pelvic fluid also can be identified readily on TVS images. The presence of solid, complex, cystic, or bilateral masses, with or without free fluid, increases the possibility of malignancy.

GCTs have a heterogeneous appearance on both sonographic and CT imaging, depending on the histologic pattern. Most commonly, they appear as round-to-ovoid masses that are multicystic, sometimes with solid components at the center or periphery. Fewer cases appear as unilocular simple or complex cysts or even homogeneous solid masses. The average size of these tumors is 12 cm, but they can range from 2-50 cm.
