摘要: Abstract Methotrexate (MTX)-associated lymphoproliferative disorders (MTX-LPDs) that occur in rheumatoid arthritis patients who were administered MTX for long periods are well known. However, studies on their pathology forming hepatic tumors rare. An approach using diagnostic imaging modalities, mainly computed tomography (CT), is considered a very useful tool the differential diagnosis of various tumors. In present study, detailed findings dynamic CT, magnetic resonance (MR) imaging, and contrast-enhanced ultrasonography tumor was confirmed as infected by Epstein–Barr virus, patient presented.
