The purpose of this exhibit is: 1. To understand the significant role of imaging in gallbladder cancer staging 2. To discuss the findings and limitations of the images generated by ultrasonography (US), endoscopic ultrasoundscopy (EUS), computed tomography (CT), and magnetic resonance imaging (MRI) for evaluation of cancer invasion and spread 3. To discuss the differences between benign and malignant tumors

CONTENT ORGANIZATION 1. Study of gallbladder cancer T-staging using different modalities 2. N-staging review and assessment of distant metastases and disseminations 3. Discuss the differential diagnosis of benign tumors such as xanthogranulomatous cholecystitis, adenomyomatosis, Mirizzi’s syndrome, and pericholecystic abscess 4. Case-based illustration of gallbladder tumors with histopathological correlation. SUMMARY Accurate evaluation of gallbladder wall invasion and extra-wall spread is essential to ascertain the appropriate therapeutic strategies for gallbladder cancer. In addition, it is essential to evaluate gallbladder wall invasion with a combination of various modalities, including transabdominal US, EUS, CT, and MRI and to ascertain the role of each modality in ensuring accurate diagnosis.
