Inflammatory myofibroblastic pseudotumours of the liver are rare tumour-like lesions that can mimic malignant liver neoplasms. The symptoms and radiological findings of this rare tumour can pose diagnostic difficulties. We describe a 69-year-old gentleman who was admitted to our department with symptoms suggestive of acute cholecystitis. Ultrasonography and computed tomography of the liver raised the possibility of metastatic liver disease. A core biopsy of the liver was performed to confirm the diagnosis of liver metastasis. Unexpectedly it showed no evidence of malignancy but instead revealed an inflammatory myofibroblastic pseudotumour of the liver. This case report highlights the diagnostic dilemma that arose due to the similarity of appearances between the two pathological entities on imaging and this stresses the need for accurate histological diagnosis so as to avoid unnecessary surgical intervention. To the best of our knowledge, only a minority of cases are reported in the literature associating a hepatic inflammatory myofibroblastic pseudotumour with gall stones.
