1. Review etiologies of RUQ pain not caused by the gallbladder. 2. Highlight the ultrasound appearance of reviewed pathology. 3. Provide an overview of disease management including correlative imaging with CT, MRI, and/or PET/CT.  

While gallbladder pathology is the most common cause of right upper quadrant pain, numerous additional etiologies may cause a similar clinical picture. Ultrasound is frequently the triage examination, giving the radiologist an opportunity to discern the correct diagnosis or next management step. Using a quiz format, the differential diagnosis of RUQ pain will be reviewed, with emphasis placed on the ultrasound appearance of each disease process. Further characterization with CT, MR, and PET/CT imaging will be provided, followed by a brief discussion and synopsis of patient management. Cases will be presented by organ and disease process, including: - Infectious and inflammatory: acute hepatitis (Hepatitis B, mononucleosis, and drug induced), hepatic abscess (bacterial and fungal), and cholangitis. Also pancreatic pseudocyst, pyelonephritis, and pyonephrosis. - Vascular, including hepatic infarct, veno-occlusive disease, portal vein thrombosis, pseudoaneurysm formation. Neoplastic:- Hepatic, biliary, and pancreatic tumors. Obstructive: Bowel, biliary, pancreatic and renal.
