What condition is typically characterized by LLQ pain with a palpable mass?

Diverticulitis is a condition that occurs when diverticula, which are small pouches that can form in the lining of the colon, become inflamed or infected. One of the hallmark symptoms of diverticulitis is left lower quadrant (LLQ) pain, as the sigmoid colon, where diverticula are most commonly located, is situated on the left side of the abdomen. Additionally, patients may present with a palpable mass, which can be due to inflammation, abscess formation, or other complications associated with diverticulitis.

The presence of LLQ pain along with a palpable mass serves as a key distinguishing feature of diverticulitis. This symptom combination aids healthcare providers in making an accurate diagnosis and differentiating it from other abdominal conditions. While appendicitis, cholecystitis, and peritonitis can also cause abdominal pain, they are typically associated with different pain locations and presentations. Appendicitis usually manifests with right lower quadrant pain. Cholecystitis is characterized by right upper quadrant pain, and peritonitis generally presents with generalized abdominal pain rather than localized discomfort along with a palpable mass.
