Abstract

Inflammatory myofibroblastic tumor (IMT) is a rare benign disease that is characterized by pseudosarcomatous proliferation consisting of spindled myofibroblast cells admixed with various inflammatory cells. IMT may mimic malignancy, clinically and radiologically. Consequently, most IMTs in the liver are removed surgically by hepatic resection with a confirmative diagnosis made later. However, current reports indicate that a minimally invasive pathologic examination and medical therapy might be sufficient treatment. We report two cases of IMT of the liver diagnosed by ultrasonography (US)-guided biopsies. Case 1: A 26-year-old man presented with right upper quadrant pain, and abdominal computerized tomography (CT) showed multiple liver abscesses. He was diagnosed with IMT on an US-guided biopsy and treated with antibiotics. Case 2: A 47-year-old man presented with three target lesions in the right lobe of the liver on abdominal CT. An US-guided biopsy showed a myofibroblastic tumor that resolved with conservative therapy.
