Corwin MT, et al. - A sum of 116 individuals were studied to ascertain the computed tomography (CT) characteristics of malignancy in incidental focal fundal gallbladder wall thickening along with its prevalence. Researchers classified the morphologies as: type 1 (nodular/pinched intramural low attenuation), type 2 (intramural low attenuation), type 3 (homogeneous enhancement), type 4 (nodular/pinched homogeneous enhancement), type 5 (intramural cystic spaces), and type 6 (hyperenhancing/heterogeneous enhancement). They observed the prevalence of these types in the following population distribution: type 1 in 57 cases, type 2 in 10, type 3 in 6, type 4 in 19, type 5 in 14, and type 6 in 10 subjects. Only 4 cases of malignancy were recorded. They noted a higher incidence of benign focal fundal gallbladder wall thickening. They found CT features with the ability to differentiate benign from malignant etiologies.
