Core Tip

Core Tip: Epiploic appendagitis should be considered in patients presenting with acute, localized lower abdominal pain without systemic symptoms. It often mimics diverticulitis or appendicitis but typically lacks fever, leukocytosis, or migratory pain. Computed tomography (CT) remains the gold standard for diagnosis, revealing a small, fat-density ovoid lesion adjacent to the colon with a hyperattenuating rim and, sometimes, a central dot sign. Management is conservative with nonsteroidal anti-inflammatory drugs and observation, as the condition is self-limiting. Awareness of persistent residual CT findings is essential to avoid confusion during future imaging. Improving clinician awareness can prevent unnecessary antibiotics, hospitalizations, and surgeries.
