Abstract

An inflammatory myofibroblastic tumor (IMT) is a rare benign hepatic neoplasm that is characterized by a mass of localized proliferations of fibroblasts and infiltrations of mononuclear inflammatory cells. An IMT can occur in a variety of locations, including the lung, orbit, parotid, pleura and stomach. However, they have rarely been encountered in the liver. An IMT of the liver most often presents in young adults. The clinical presentations of a hepatic IMT vary: asymtomatic, fever, abdominal pain, palpable mass, vomiting, obstructive jaundice, anemia and hepatosplenomegaly. Their radiographic appearance and clinical presentation make them extremely difficult to distinguish from a malignant neoplasm, preoperatively. Therefore, surgical management is used when a malignancy can not be excluded preoperatively or when the IMT produces a biliary obstruction. We encountered a 31-year-old male patient who is still alive for 38 months following a resection for symtomatic IMT.
