Inflammatory myofibroblastic tumor of the liver was first described in 1953 by Pack and Baker.
Different synonyms have been used in het literature; Inflammatory pseudotumor,
Xanthogranuloma type pseudotumor,
Plasma cell granuloma,
Histiocytoma and " Plasmacytoma".
the most used name is inflammatory pseudotumor.
Inflammatory myofibroblastic tumor is a localized mass consisting of a fibrous stroma and chronic inflammatory infiltrates with a predominance of plasma cells or histiocytes and an absence of anaplasia.
Up to now there has been only few case reports publishing about this entity.
there are no studies describing the difference on imaging between inflammatory pseudotumor and cholangiocarcinoma.
in our experience those two entities could look very similar.
This lead us to investigate whether Inflammatory Myofibroblastic Tumor (IMT) of the hepatobiliary system,
which is a benign entity,
can be differentiated from its malignant look-a-like CholangioCarcinoma (CC)
