A 48-year-old woman had liver cirrhosis complicated with intractable ascites. She underwent a Denver shunt (peritoneovenous shunt) procedure 1 year ago. Suspicion of dysfunction of the Denver shunt led to her referral for peritoneal scintigraphy. Instead of confirmation of shunt dysfunction, there were also findings of bilateral peritoneopleural communications. Nevertheless, it was also found as well-demarcated, circumferential accumulation of the radiotracer as well as scattered distributed, photopenic areas within the center of the abdomen, which was distinguished from the peripheral diffuse distribution of radioactivity in the peripheral abdominal region. The assumption of the accumulation of radiotracer in the center of the abdomen after physical examination was an umbilical hernia that was further confirmed by subsequent abdominal computed tomography.
