Ram's horn sign

Last revised by Dr Joshua Yap on 09 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
