Click 54-year-old man with combined undifferentiated and neuroendocrine carcinoma of the gallbladder.
FINDINGS: Abdominal ultrasound shows a heterogeneously echogenic polypoid mass at the fundus of the gallbladder with subtle increased power Doppler flow. A short distance from the main mass, focal nodular thickening of gallbladder wall is noted with prominently increased power Doppler flow. About 1 cm sized hypoechoic hepatic nodule is noted at segment 5 of the liver adjacent to the gallbladder fossa. TECHNIQUE: Philips, HDI 5000; 2-5–MHz convex transducer

FINDINGS: Axial Triphasic MDCT stack of the abdomen shows a polypoid mass at the fundus of the gallbladder, which reveals heterogeneous enhancement similar to that of the fatty liver parenchyma and includes a central necrotic portion. Focal marginal blurring is noted at the fundus of the gallbladder with suspected pericholecystic infiltration. A short distance from this mass, focal nodular thickening of the gallbladder wall is suspected, and it reveals more intense enhancement during all phases compared with the main mass. There is a subtle focal low-density lesion in segment 5 of the liver adjacent to the gallbladder fossa on arterial and venous phase images. A 2.5 x 1 cm sized homogeneously enhancing portocaval lymph node is detected without evidence of necrosis. TECHNIQUE: Precontrast phase of triphasic MDCT. Siemens Healthcare, SOMATOM Definition Flash, Axial CT. 80~165mA, 120kV, 3mm slice thickness, intravenous contrast: 120 mL of contrast medium (Iopromide, Ultravist 370, Bayer HealthCare)
