An abdominal ultrasound image shows a large heterogeneous echogenic mass in the expected region of the gallbladder. The echo-free rounded cystic lesion posteriorly is a [renal cortical cyst]. In the region of the porta hepatis is a gallstone. Doppler examination (not shown) demonstrated vascularity within the gallbladder mass.
This 85 year-old female presented with abdominal pain. An MR was performed which confirmed the ultrasound findings. Extensive liver metastases were also demonstrated.
Gallbladder carcinoma may present as a large mass infiltrating the liver and gallbladder fossa, an intraluminal mass (as in this case), or focal or diffuse mural thickening. Seventy-five percent of patients have gallstones. GB carcinoma is most commonly found in elderly females. Gallstones, chronic cholecystitis and porcelein gallbladder are risk factors for the development of GB carcinoma.
