Differentiation of peritoneal tuberculosis from peritoneal carcinomatosis by the Omental Rim sign. A new sign on contrast enhanced multidetector computed tomography

摘要

Introduction: Peritoneal TB (PTB) is the commonest presentation of abdominal TB. One of its close mimics is peritoneal carcinomatosis (PC). We present a new sign of PTB on contrast enhanced multidetector computed tomography (CT) called the Omental Rim (CT-OR) sign which helps to accurately differentiate PTB from PC.
