title: Different imaging findings of inflammatory myofibroblastic tumor of the liver.
abstract: Inflammatory myofibroblastic tumor (IMT) in the liver is an uncommon lesion of uncertain pathogenesis. In most cases, symptomatological imaging and clinical studies suggest malignancy. We report a case of liver IMT with imaging findings from positron emission tomography/computed tomography (PET/CT), contrast-enhanced computed tomography (CECT) and contrast-enhanced ultrasonography (CEUS). This report was the first to depict a PET/CT scan of a liver IMT that revealed an inhomogeneous, intense (fluorine 18)-fluoro-2-deoxy-D-glucose uptake. The CECT and CEUS images showed a hepatic artery supplying blood to the mass and necrosis. The characteristic histopathological features and the presence of spindle cells expressing smooth muscle actin, collagen fibers and lymphocytes allowed for the diagnosis of liver IMT. Recognizing such findings will help to achieve a correct diagnosis and may prevent inappropriate treatment.
