The findings of XXXX on helical CT.

@entity1 @entity157 @entity5
To evaluate the helical CT findings of @entity157 ( @entity157 ), 12 @entity1 with @entity157 were reviewed with regard to the @entity5 's location, size and contour protrusion, the appearance of the mass, the enhancement pattern, multiplicity and secondary changes. All @entity5 were located at the periphery of the liver and had a protruding contour. The maximum diameter of @entity5 ranged from 2 cm to 16 cm. Discontinuity of the hepatic surface was seen in 11 cases. In eight cases, CT images during the arterial phase showed a non-enhancing low attenuating lesion with focal discontinuity and peripheral rim enhancement. Seven cases showed @entity5 content from the peripheral enhancing rim and intraperitoneal @entity5 content into the perihepatic space. Because of the similar appearance to an enucleated orbital globe with remaining sclera, this was termed the "enucleation sign". As well as ruptured masses, 10 cases with non-ruptured masses also showed a non-enhancing low attenuating pattern. Seven cases showed a haematoma with high attenuation around the ruptured mass. The peripheral location, protruding contour, discontinuity of the hepatic surface and surrounding haematoma are helpful signs in the diagnosis of @entity157 . The "enucleation sign" may be a characteristic finding in @entity157 .
