@entity6437 ( @entity6437 ) is a rare @entity5 of unknown origin, it has the appearance of a @entity5 but has a benign histology and clinical course. Therefore, we studied five @entity1 with @entity6437 of the liver to determine what examination can aid in its diagnosis. Five cases of @entity409 were analyzed. All @entity1 were examined by echography, computed tomography (CT), magnetic resonance imaging (MRI), endoscopic retrograde cholangiography (ERC) and angiography to diagnose the @entity96 . In all @entity1 echography and CT scan showed a similar appearance while MRI showed a variable pattern. In two @entity1 ERC showed a stenotic image of intra-hepatic bile ducts. In the angiographic study, the arterial phase in three @entity1 showed a hypervascular @entity5 and in one @entity1 , a @entity5 . @entity455 was presented in one @entity1 . Similarly, portography in four @entity1 showed some abnormality. We performed ultrasonography-guided percutaneous needle biopsy in two @entity1 in order to diagnose @entity6437 . Histological examinations of two @entity1 were consistent with @entity6437 . The other three @entity1 underwent surgical treatment for a @entity201 or @entity733 . It is difficult to diagnose @entity6437 of the liver exclusively with an image examination. Ultrasonography-guided percutaneous liver biopsy should be performed in order to diagnose @entity6437 by histology.
