What are the characteristics of haemangioma on CT scan?
Hypoattenuating lesion, with peripheral nodular discontinuous enhancement during arterial phase, followed by centripetal enhancement on venous phase CT.
- Liver segment II mass measuring 34 x 30 mm which demonstrates minor nodular peripheral enhancement on the arterial phase, seen to demonstrate further nodular enhancement and filling on portal venous and delayed phases. The mass demonstrates increased attenuation compared with the remainder of the liver on delayed phase. These features would be in keeping with a haemangioma. No evidence to suggest bleeding.
- Liver segment VII low attenuation lesion present measuring 5 mm demonstrated on the portal venous phase but not on the delayed or arterial phases is nonspecific but may also represent a haemangioma.
- Liver segment IVa low attenuation lesion demonstrated on the portal venous phase but not on the arterial or delayed phase. This is nonspecific but may also represent a haemangioma.
