Gallbladder: common cause of antral pad sign
AJR. American Journal of Roentgenology
|April 1, 1979
Summary
The "antral pad sign" on gastric imaging can indicate pancreatic masses, but gallbladder indentation is a more frequent cause. Always rule out gallbladder issues first when this sign appears.
Area of Science:
- Gastroenterology
- Radiology
- Medical Imaging
Background:
- The antral pad sign is an imaging finding on the posteroinferior aspect of the gastric antrum.
- This sign can be caused by extrinsic compression from adjacent organs.
Purpose of the Study:
- To differentiate the causes of the antral pad sign.
- To emphasize the importance of considering gallbladder pathology.
Main Methods:
- Review of imaging studies demonstrating the antral pad sign.
- Correlation with pathological findings and clinical data.
Main Results:
- Pancreatic mass lesions are a potential cause of the antral pad sign.
- Gallbladder-related impressions are a more common etiology.
Conclusions:
- The antral pad sign necessitates careful evaluation to distinguish between pancreatic and gallbladder origins.
- Exclusion of gallbladder pathology is a critical first step in diagnosing the antral pad sign.
