INTRODUCTION: Inflammatory pseudotumor (IPT) is a rare lesion consisted of inflammatory and myofibroblastic cells. These lesions may be found in different organs. There are less than 300 described cases. PRESENTATION OF CASE: Case 1. 64-year-old cirrhotic male with a palpable epigastric mass. CT showed a lesion in liver segments 2 and 3 and left hepatic artery aneurism. Percutaneous embolization and wide spectrum antibiotics were tried, however the lesion grew. Left lateral hepatectomy was performed, and HIPT diagnosed. The patient died due to multiple organ dysfunction. Case 2. 30-year-old male with abdominal pain and fever. CT showed a hepatic hilar lesion. Surgical resection was performed after an ineffectual antibiotic trial, and HIPT was confirmed. The patient is doing well. Case 3. 73-year-old female with abdominal pain and fever. CT showed a 7 cm lesion in the left liver lobe. Unrewarding cancerous screening was performed, and unsuccessful antibiotic course was tried. Resection was performed, and HIPT diagnosed. The patient is doing well. Case 4. 50-year-old cirrhotic male with abdominal pain. CT showed a segment 6 lesion and portal vein thrombosis. Considering cancer as the first hypothesis and the MELD score of 9, segmentectomy was performed. HIPT was the final diagnosis. The patient died due to abdominal sepsis. DISCUSSION: HIPT is a lesion with a vast list of differential diagnosis. Antibiotics are the first line of therapy, although surgery is often necessary. Overall prognosis is good, although comorbidities may worsen it. CONCLUSION: HIPT is a rare and misleading entity. © 2013 Surgical Associates Ltd.
