To Evaluate Role of Transvaginal Sonography over Transabdominal Sonography in Delineating Adnexal Masses

ABSTRACT

To compare and find diagnostic accuracy of Transvaginal sonography (TVS) over Transabdominalsonography (TAS) in evaluation of adnexal lesions. A cross sectional comparative study of 50 patientsincluding both pre and postmenopausal women who were clinically suspected to have adnexal masswere scanned on Logiq GE C5 Premium ultrasonography unit. TAS was performed with 3.5MHzelectronic macro convex probe followed by TVS with 6.5 MHz end firing electronic TVS probe. TVSwas found to be superior in diagnosing adnexal lesions. In comparison with TAS, TVS diagnosedbenign cystic teratomas (100% versus 40%), endometriomas (90% versus 57.1%), haemorrhagic ovarian cysts (85.7% versus 50%, hydrosalpinx (75% versus 25%), pyosalpinx/tubo-ovarian mass (75%versus 75%), and ectopic pregnancy (100% versus 77.7%). In our study ovarian cancers were betterdetected by TAS due to their large size. TVS was found to be superior in diagnosing adnexal masses ascompared to TAS with more accurate delineation of internal architectural features as wall thicknessand complexity, nodules, septae, papillary projections, internal echoes thereby narrowing the differentials.
