Abstract:
CME Sonography 91: Differential Diagnosis of Lower Abdominal Pain Abstract. Pain in the lower abdomen is a frequent reason for further imaging clarification by sonography. The most frequent causes are appendicitis and diverticulitis, in addition to ureteral stones, ovarian and tubal pathology as well as various hernias. Appendicitis has a characteristic clinical presentation and can be diagnosed by CT or ultrasound. In children, the differential diagnosis is that of mesenteric lymphadenitis. Diverticulitis, often right-sided, can also be reliably diagnosed with CT or ultrasound. Not to be forgotten is the left-sided diverticulitis, which occurs more frequently in Asian persons. Appendicitis epiploica should be recognized to avoid unnecessary operations. The iliopsoas syndrome, which is diagnosed by sonopalpation, often remains undetected.

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
