A 73-year-old man was admitted to our hospital for the diagnosis of pneumonia and bronchial asthma. He was treated for hepatocellular carcinoma (HCC) with transcatheter arterial embolization (TAE) and percutaneous ethanol injection therapy (PEIT) at other hospital four years ago. By contrast CT scan he was diagnosed as a reccurent HCC in the diameter of 1 cm located on Segment 4. The tumor was not detected by ultrasonography and his respiratory function wasn't good enough for surgical resection. Then we performed CT-guided percutaneous microwave coagulation therapy. Seventh post-therapeutic day contrast CT scan revealed a low density area without enhancement showing the complete necrosis of the tumor. The patient was discharged without any complication on the 14th post-therapeutic day.
CT-guided percutaneous microwave coagulation therapy is useful therapy for HCC which was not detected by ultrasonography.
