[Ultrasound diagnosis of non-aneurysmic pulsating abdominal tumors]
Abstract:
Ninety-two patients with a pulsating abdominal mass and suspected abdominal aortic aneurysm (AAcA) were examined by ultrasonography. We diagnosed 48 cases (52%) of AAA and 5 unexpected lesions ventral to the aorta (5%), but in 39 cases (42%) we were not able to explain the symptom in spite of extensive diagnostic efforts and follow-up. Changes of the aorta or transmission of the pulse by adjacent structures are the main cause of a pulsating abdominal mass. Ultrasound examination appears to be optimal screening method for diagnosing AAA as well as the other symptoms no further diagnostic efforts are necessary after a negative ultrasound study.

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.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.

Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
