Inflammatory pseudotumour of the liver: a diagnostic dilemma.

ABSTRACT

Inflammatory pseudotumour is a rare, focal, benign inflammatory lesion of the liver parenchyma. It is largely a self-limiting entity and has favorable prognosis; it is thus important to preoperatively distinguish this lesion from malignancy, which it closely imitates. Inflammatory pseudotumour may present variously. We present the case of a 54-year old gentleman who presented with a three-month history of low-grade intermittent fever. Ultrasonography and computed tomography revealed a mass in the left lobe of the liver and the erythrocyte sedimentation rate was raised with coincident hypergammaglobulinaemia. A diagnostic laparotomy with left lateral hepatectomy was performed and histopathological evaluation of the specimen along with special staining and tissue culture revealed an inflammatory pseudotumour. On the second day post-operative the fever subsided and following an uneventful five days the patient was discharged and remains well at one-year follow up with no recurrence or relapse.
