摘要:

Transvaginal sonography (TVS) is particitlarly suited for evaluation of patients with pelvic masses that lie in the true pelvis (not over 10 cm). For larger pelvic masses, transvaginal sonography has only an adjunctive role to transabdominal sonography (TAS). The added definition of the size, location, and internal consistency of pelvic masses affordded by transvaginal sonography makes it the imaging modality of choice for most pelvic masses (Figure I).(Figure I).Whether or not transvaginal sonography is used alone or in combination with transabdominal sonography is up to the preference of each individual imager. However, I prefer to perform an initial transabdominal sonographic survey, for global depiction followed by transvaginal sonographv of a specific area. Independent of which technique is used, one should strive to arrive at the most speclfic diagnosis based upon those transvaginal sonography features and clinical presentation. The clinically pertinent features of a pelvic mass that can be depicted by transvaginal sonographv include: (1) its size and location (i.e., ovarian, uterine, or other); (2) internal consistency (ie., totally cystic, low level echoes, septations, papillary projections, mirral nodules, fat, calcifications); and (3) associated abnormalities (i.e. intraperitoneal fluid).Rather than classifying masses into cystic, complex, and solid categories, as with conventional transabdominal sonography, transvaginal sonography affords a more specific differential diagnosis based on more precise delineation, such as the location and internal consistency of the mass. This review will reflect the more specific classification afforded by transvaginal sonography than has been previously possible with conventional transabdominal sonography. Table 1 provides a guide for differential diagnosis of pelvic masses primarily using transvaginal sonography as an adjunct to transabdominal scanning. The following discussion is presented according to these major categories.
