Intra-abdominal actinomycosis with hepatic pseudotumor and xanthogranulomatous pyelonephritis in a 6-y-old boy

Abstract

We report the case of a 6-y-old boy with actinomycosis, presenting as xanthogranulomatous pyelonephritis (XGP), hepatic pseudotumor and abdominal abscess. Symptoms included intermittent fever, abdominal pain and significant weight loss. Hepatic and renal tumor masses were suspected on sonography and computerized tomography. XGP and actinomycosis were proven by pathology. The patient recovered well with antibiotic alone.
