Inflammatory Pseudo-tumor of the Liver Accompanied by Eosinophilia

A 28-year-old woman was referred to our hospital for liver dysfunction and neck pain. Blood tests revealed elevated liver enzymes and eosinophilia. Ultrasonography, computed tomography, and magnetic resonance imaging showed a mass lesion near the hepatic hilus. The tumor was considered to be an inflammatory pseudo-tumor or malignancy. A liver-mass biopsy was performed and led to a diagnosis of inflammatory pseudo-tumor. In the present case, a markedly elevated eosinophil count was a characteristic clinical feature, and the patient underwent steroid therapy. Treatment resulted in a reduced eosinophil count, improved neck symptoms, and disappearance of the inflammatory pseudo-tumor.
