Ram's horn sign

Last revised by Joshua Yap on 9 May 2022

The Ram's horn sign, also known as Shofar sign, is the tubular, conical appearance of the stomach antrum seen on a barium meal. The stomach is less distensible and the curved conical appearance resembles the horn of a ram.

This is seen in granulomatous disease, typically Crohn disease, but also in tuberculosis, syphilis and sarcoidosis 3
