A 54-year-old man, who had been treated previously for the rupture of esophageal varices, was admitted to the hospital with the chief complaint of right hypochondralgia. The patient underwent surgery under the preoperative diagnosis of pedunculated hepatocellular carcinoma by means of ultrasonography, computed tomography and angiography. But postoperative diagnosis was abdominal actinomycosis. We can't prove the actinomycosis from gastrointestinal tract. It is difficult to diagnose the disease preoperatively with differential diagnosis of only roentgen. Abdominal actinomycosis is not a common disease but should be taken into consideration in the differential diagnosis of abdominal mass, which can't be diagnosed preoperatively.
