Gallbladder disease presents in which quadrant?

• A. LLQ
• B. RUQ
• C. LUQ
• D. RLQ

Answer: (B)

Pain from gallbladder disease shows up in the right upper quadrant because the gallbladder rests on the underside of the liver in that region. Inflammation or gallstones irritate the gallbladder wall, causing tenderness under the right costal margin, and the痛 can sometimes radiate to the right shoulder or back due to diaphragmatic irritation. Other quadrants house different organs—left upper has stomach and spleen, left lower has portions of colon, and right lower has the appendix—so gallbladder-related pain is most consistent with the right upper quadrant.
