antral pad sign
The antral pad sign is a feature seen on a spot radiograph of the upper gastrointestinal tract obtained with orally-administered contrast material. It refers to the extrinsic impression or indentation on the posteroinferior aspect of the antrum. The impression is generally arcuate and smooth, and it may or may not be associated with an impression on the medial aspect of the duodenum.
Differentials to be considered when the antral pad sign is seen include:
- pancreatic carcinoma head/body
- pancreatitis
- pancreatic pseudocyst
- normal distended gallbladder with the patient in a right anterior oblique position
