We present two cases of inflammatory pseudotumor (IPT) of the liver and a review of the literature. Case 1: A 56-year-old woman was admitted to the hospital because of appetite loss and vomiting. Abdominal ultrasonography and CT scan showed a heterogeneous mass with irregular margin in the right lobe of the liver. Pelvic CT scan demonstrated an irregular-shaped tumor 6×5cm in size. Under a presumable diagnosis of pelvic tumor with liver metastasis, hysterectomy, bilateral oophorectomy and right lobectomy of the liver were performed. Histological diagnosis was endometroid adenocarcinoma of the right ovary annd IPT of the liver. Case 2: A 51-year-old man was admitted to the hospital because of fever. Abdominal ultrasonography and CT scan demonstrated an irregular heterogeneous mass with 4.3cm in diameter in S6, 7 of the liver. Histological findings of needle biopsy specimen revealed inflammatory fibrous tissue with infiltration of macrophages, lymphocytes and plasma cells. Since malignant disease could not be completely ruled out, a right lobectomy of the liver was carried out. Histologically, the diagnosis of IPT was established. It is suggested that we should entertain the disease as a probable diagnosis for liver tumors with inflammatory reaction.
