A 40-year-old female presenting with mild fever and liver mass on US examination. Axial plane postcontrast CT image demonstrates ill-defined, hypoattenuating mass (arrows) in the right lobe with accompanying wide parenchymal area of disturbed perfusion. Percutaneous biopsy revealed basophilic aggregates and sulfur granules consistent with actinomycetes infection. Post-antibiotic treatment demonstrated almost complete regression of the imaging findings (not shown)
