Abstract
The patient was a 54-year-old woman with liver dysfunction that was diagnosed during a routine health examination. A hepatic mass was detected on examination, for which she was referred to our department for consultation. Computed tomography revealed two masses (diameters 10 and 15 mm, respectively) without contrast enhancement in the center and marginal enhancement in S6. Magnetic resonance imaging revealed low-signal intensity masses on T1-weighted images that showed high signal intensities on T2- and diffusion-weighted images. The masses were small and therefore were expected to increase in size. Partial liver resection involving S6 was performed. Histopathological analysis revealed marked inflammatory cell infiltration and fibrous elements that led to the diagnosis of inflammatory pseudotumor of the liver. Blood test results confirmed Epstein-Barr virus infection. This indicates that the inflammatory pseudotumor of the liver in this case may have been associated with chronic Epstein-Barr virus infection.
