title: A succesfully managed inflammatory pseudotumour of liver without surgery: report of a case.
abstract: The inflammatory pseudotumor (IPT) of the liver is an extremely rare focal lesion of the parenchyma with unknown aetiology. It has the appearance of a malignant tumor but has a benign histology and clinical course. Herein, we report a case of IPT in a 55 year-old woman. She had complained of right upper quadrant pain and subfebrile fever. Imaging studies revealed a heterogeneous, solitary mass in right lobe of liver which was 90 x 81 mm in size. Histopathological examination of ultrasonography-guided true-cut biopsy demonstrated IPT. After the initiation of the antibiotic and nonsteroidal anti-inflammatory drugs (NSAID), the size of hepatic pseudotumor decreased (20 x 20 mm) and then completely disappeared. To rule out a malignancy and to reach the diagnosis of IPT, biopsy from the mass is mandatory. After the diagnosis, IPT gave an excellent response to short course of antibiotic and NSAID therapy. To prevent unnecessary resective liver surgery, IPT should be kept in mind in the differential diagnosis of liver mass which can be successfully managed medically.
