title: Carcinoma of the gallbladder: color Doppler ultrasound and CT findings.
abstract: A case of a large polypoidal gallbladder carcinoma presenting with empyema is described. Heterogeneous echoes filled the gallbladder lumen on gray-scale sonography. Color Doppler ultrasound detected vascularity within the gallbladder lumen, thereby differentiating the intraluminal tumor from isoechoic sludge and pus. Correlative computed tomography showed an enhancing intraluminal mass, with small enhancing vessels that corresponded to those seen with color Doppler sonography.
