A 60-year-old man presented with a 10-day history of abdominal and back pain. Abdominal contrast-enhanced computed tomography showed an intraperitoneal abscess (Figure 1). Antibiotic therapy with flomoxef resulted in reduced size but not the total disappearance of the abscess. Laparoscopic surgery was performed. In addition to the masslike structure in the greater omentum (Figure 2A), numerous white nodules were found on the peritoneum (Figure 2B). Pathological examination showed granulomatous inflammation around parasite eggs (Figure 2C and D). The patient had eaten raw wild boar meat 7 months ago. Total serum immunoglobulin E was elevated (433.9 IU/mL), but total white blood cell and eosinophil counts were within the reference intervals. Serological examination revealed a positive reaction to Paragonimus antigens. A diagnosis of abdominal paragonimiasis was made. The patient’s symptoms resolved after the surgery. Praziquantel (75 mg/kg/daily for 3 consecutive days) was administered postoperatively. The patient has been free from symptoms for 3 months of follow-up.
