Contrast‐enhanced sonography of a hepatocellular carcinoma undergoing spontaneous necrosis

Abstract

Spontaneous necrosis of hepatocellular carcinoma (HCC) is rare. We report the case of a 72-year-old woman with an HCC nodule that underwent necrosis after sonographically guided needle biopsy. Baseline sonographic examination revealed only a nonspecific change in the echogenicity of the lesion. Subsequent necrosis was suggested on contrast-enhanced sonographic examination and was confirmed on spiral CT.

Contrast-enhanced ultrasonography for the diagnosis of spontaneous necrosis of hepatocellular carcinoma: A report of 2 cases

“…Diagnosis becomes quite difficult if spontaneous necrosis occurs before definitive diagnosis, because the imaging features of spontaneous regression of HCC are not uniform. Because the usefulness of CEUS for spontaneous necrosis after a definitive diagnosis has been reported [15] , we compared the CEUS images with the pathological finding of spontaneous necrosis, and assessed the possibility of preoperative diagnosis using CEUS.…”
