Xanthogranulomatous cholecystitis mimicking gallbladder carcinoma

Figure 2 Multimodal preoperative imaging of xanthogranulomatous cholecystitis mimicking gallbladder carcinoma. A and B: Contrast-enhanced computed tomography in the portal venous and arterial phases showing marked irregular thickening of the gallbladder wall and loss of the cleavage plane with the adjacent liver parenchyma; C: Diffusion-weighted magnetic resonance imaging demonstrating marked diffusion restriction in the gallbladder body-fundus region, further raising suspicion for a neoplastic lesion; D: T2-weighted magnetic resonance imaging showing abnormal gallbladder wall thickening and pericholecystic inflammatory changes, with poor demarcation from the adjacent hepatic parenchyma.
