What structure is typically visualized as a "target sign" in abdominal ultrasounds?

The structure referred to as a "target sign" in abdominal ultrasounds is commonly associated with intussusception. This appearance arises due to the layering of bowel walls as one segment of the intestine telescopes into an adjacent segment, creating concentric rings that resemble a target. This distinct visual pattern can indicate the presence of intussusception, which is a critical condition that requires prompt diagnosis and management.

In contrast, while other structures such as the liver or gallbladder may exhibit various sonographic features, they do not typically present with the characteristic "target sign" observed in cases of intussusception, which is specifically indicative of bowel pathology. Understanding these specific sonographic patterns is essential for accurate diagnosis and treatment planning in abdominal ultrasound imaging.
