Diverticulitis is most commonly associated with which abdominal quadrant?

• A. LLQ
• B. LUQ
• C. RLQ
• D. RUQ

Answer: (A)

Diverticulitis most often involves the sigmoid colon, and the sigmoid portion sits in the left lower quadrant of the abdomen. That anatomical location means the classic inflammation-related pain is felt in the left lower quadrant. The other quadrants correspond to other organs (appendix in the right lower quadrant, gallbladder/lats of liver in the right upper quadrant, stomach/spleen in the left upper quadrant), so the left lower quadrant is the typical association for diverticulitis.
