Abstract:
Although the double wall or muscular rim sign is considered to be a characteristic sonographic imaging finding of an enteric duplication cyst, this sign can also be produced by Meckel's diverticulum and sonographic artifacts. The Y-configuration on in vitro sonography has been reported to be useful for the definitive diagnosis of an enteric duplication cyst. Here, we report a case of an intraoperatively confirmed ileal duplication cyst that was correctly diagnosed before by identification of the Y-configuration on in vivo sonography.

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...
