abstract: @entity7 ( @entity7 ) is a rare @entity1 of unknown origin, it has the appearance of a @entity1 but has a benign histology and clinical course. Therefore, we studied five @entity0 with @entity7 of the liver to determine what examination can aid in its diagnosis. Five cases of @entity4 were analyzed. All @entity0 were examined by echography, computed tomography (CT), magnetic resonance imaging (MRI), endoscopic retrograde cholangiography (ERC) and angiography to diagnose the @entity2 . In all @entity0 echography and CT scan showed a similar appearance while MRI showed a variable pattern. In two @entity0 ERC showed a stenotic image of intra-hepatic bile ducts. In the angiographic study, the arterial phase in three @entity0 showed a hypervascular @entity1 and in one @entity0 , a @entity1 . @entity5 was presented in one @entity0 . Similarly, portography in four @entity0 showed some abnormality. We performed ultrasonography-guided percutaneous needle biopsy in two @entity0 in order to diagnose @entity7 . Histological examinations of two @entity0 were consistent with @entity7 . The other three @entity0 underwent surgical treatment for a @entity3 or @entity6 . It is difficult to diagnose @entity7 of the liver exclusively with an image examination. Ultrasonography-guided percutaneous liver biopsy should be performed in order to diagnose @entity7 by histology.
