Estudo Prospectivo das Características Sonográficas no Diagnóstico de Nódulos Sólidos da Mama

Abstract: Resultados: dentre as 142 pacientes incluídas no estudo, 90 (63%) tiveram suas lesões ressecadas, com diagnóstico de 77 tumores benignos (86%) e 13 de malignos (14%). Foram significantes no diagnóstico de malignidade as seguintes características ultra-sonográficas: presença de sombra acústica posterior (p=0,0001), contornos irregulares (p=0,0007), ecos internos heterogêneos (p=0,0015) e diâmetro ântero-posterior (AP) maior que o látero-lateral (LL) (p<0,0001). A presença de halo ecogênico no tumor e a visibili… Show more

“…For any isolate echographic characteristic to have practical applicability in the differentiation between malignant and benign lesions, this characteristic must be a finding with a high rate of interobserver agreement (7,8) . Considering that ultrasound is an operator-dependent method, the professional qualification, besides the operator experience, is clearly mandatory, allowing not only the images visualization, but also the utilization of morphological characteristics for differentiation between malignant and benign lesions (7)(8)(9)(10)(11) . A quantitative approach is suggested by other studies, aiming at analyzing tumors margins and texture on the basis of several mathematical techniques.…”

“…As características utilizadas na avaliação da morfologia das lesões já foram descritas por vári-os autores [5][6][7][8][9][10][11][12] e se encontram discriminadas a seguir: a forma pode ser definida (arredondada, ovóide, alongada) ou indefinida. Os limites podem ser descritos como precisos (nítidos), imprecisos (não nítidos), ou parcialmente precisos.…”

“…If the supplied image presents a specific benign lesion, i.e., BIRADS 2, concomitantly with the clinical history and physical examination, follow-up should be based on your concern or risk factors (PEARLMAN; GRIFFIN, 2010). To perform the ultrasound, the patient is placed in the supine position, with her arms raised and hands behind her head, scans are done clockwise, and they are from the periphery to the center of the breast (PAULINELLI;et al, 2002).…”
