Description

A 76-year-old woman with rheumatoid arthritis was referred to our hospital with multiple tumors in the liver, lung and kidney, which were detected by abdominal ultrasonography and enhanced computed tomography. Further, the tumor in the right lobe of the liver was diffusely and slightly enhanced, and seemed to be invading the right kidney. Although the tumors had already decreased in size by the time of admission, we performed needle liver biopsy to rule out malignancy. Pathological findings revealed severe scarred lesions with inflammatory cell invasion. Follow-up ultrasonography and CT showed a decrease in size of all the tumors, apparently with time. Based on pathological findings and serial shrinkage of the tumors in imaging modalities, the patient was diagnosed with inflammatory pseudo-tumor (IPT). While cases of IPT in one or two organs have been previously reported, to the best of our knowledge, this is the first case report of IPT in three organs.
