Hemangioma of the liver, also liver hemangioma and hepatic hemangioma, is a benign vascular tumour of the liver, that may be mistaken for metastatic disease.[1]
Hemangiomas, more generally, are dealt with in the hemangioma article.
General
- Benign.[2]
- Can be hard to differentiate from metastatic disease on imaging.[1]
- Usually an incidental finding (incidentaloma) and often asymptomatic.[2]
- Large lesions may present with upper abdominal pain.
- May cause congestive heart failure in infants - if large.[3]
Clinical:
- Do not grow in size - can be followed if small or medium size (<10 cm).[2]
Gross
- Variable size.
- Well circumscribed.
Microscopic
Features:
- Channels lined by benign endothelium containing RBCs.
DDx:

Micro
The sections show dilated vascular spaces containing red blood cells that are lined by endothelial cells without significant atypia. The vascular spaces are separated by bland fibrous tissue.
Abnormal perivascular cells are not identified. The background liver is without atypia and does not have appreciable fat.
