Haemangiomas

Haemangiomas are benign liver lesions that are virtually always harmless. They are very common and are caused by an overgrowth of blood vessels at one or more sites in the liver. They are often picked up on scans of the liver, but even very large haemangiomas do not usually require any treatment or cause any symptoms. Rarely they can appear similar to more worrying tumours on scans and under these circumstances we occasionally perform surgery to remove one to confirm that this is the correct diagnosis. However usually the appearances on scans are sufficient to confirm the diagnosis.
