[A Case in Which the ICG Fluorography Was Useful for Detecting Minute Peritoneal Disseminations]

A 65-year-old man was emergently brought to our hospital because of rupture of 10 cm hepatocellular carcinoma(HCC) at left lobe in September 2019. He underwent selective transcatheter arterial embolization(TAE)for hemostasis. Enhanced computed tomography(CT)revealed one more 26 mm HCC at segment 8(S8)in addition to the ruptured HCC. Transcatheter arterial chemoembolization(TACE)was performed for both tumors. HCC at left lobe was resistant to TACE, hence we performed left hepatectomy. During the surgery we searched for peritoneal dissemination by using indocyanine green(ICG) fluorography and found 4 nodules with ICG accumulation in the omentum. All the nodules were pathologically diagnosed as peritoneal dissemination. We reported a case in which the ICG fluorography was very useful for detecting small peritoneal disseminations.
