haematoma

The Oxford Companion to the Body | 2001 | | Copyright

haematoma A discrete internal collection of blood which has leaked from damaged blood vessels. At some sites blood can seep away between layers of tissue, but where there are tighter compartments it remains a circumscribed mass which can cause problems by putting pressure on its surroundings. A small one, for example, appears under a fingernail which has been hit with a hammer. At the other extreme a life-threatening one can occur on the surface of the brain (subdural haematoma) following a head injury.
