Ultrasonography showed double high-echoic lines around an extrahepatic hepatocellular carcinoma diagnosed in a 77-years-old woman. The mechanism of this observation is assumed to be explained by the high echo derived from the liver capsule surrounding the tumor, which was compressed into liver parenchyma by the diaphragma or inner abdominal wall. Because such double lines are ususual in cases liver tumors located in deep liver parenchyma, the sign seems important in diagnosing extrahepatic hepatocellular carcinoma. We propose the term double capsular sign for this specific and important ultrasonographic finding.
