Espessamento parietal da vesícula biliar no exame ultrassonográfico: Como interpretar?

Abstract

The present review was aimed at providing help for correct interpretation of gallbladder wall thickening and differential diagnosis at ultrasonography. Gallbladder wall thickening is a frequent sonographic finding and has been subject of great interest for being considered as a hallmark feature of acute cholecystitis, despite the fact that such a finding is observed in a number of other medical conditions. An appropriate characterization and interpretation of this finding is of great importance, considering that the correct diagnosis has a direct impact on the treatment that in some cases includes surgery. In the present article, the authors describe a set of sonographic signs that, in association with clinical and laboratory findings can reduce the number of diagnostic hypotheses allowing a more accurate establishment of the cause for gallbladder wall thickening through a rational data evaluation. © Colégio Brasileiro de Radiologia e Diagnóstico por Imagem.
