  Hematoma - Wikipedia, the free encyclopedia
A hematoma, or haematoma, is a collection of blood, generally the result of hemorrhage.
Hematomas can gradually migrate, as the effused cells and pigment move in the connective tissue.
Hematomas on articulations can reduce mobility of a member and present roughly the same symptoms as a fracture.

 Epidural hematoma - Wikipedia, the free encyclopedia
Epidural or extradural hematoma is a buildup of blood occurring between the dura mater (the brain's tough outer membrane) and the skull.
The cause of epidural hematoma is usaully traumatic, although spontaneous hemorrhage is known to occur.
Epidural hematoma commonly results from a blow to the side of the head and is frequently caused by a fracture that passes through an arterial channel in the bone, most commonly a break in temporal bone interrupting middle meningeal artery, a branch of the external carotid (Shepherd, 2004).

 Dr. Koop - Hematoma- Health Encyclopedia and Reference
Hematoma is a localized collection of blood, usually clotted, in a tissue or organ.
Less serious types include subungual hematoma (under a fingernail or toenail); hematoma auris (in the tissues of the outer ear, better known as cauliflower ear); and perianal hematoma (under the skin around the anus).
Hematomas are almost always present with a fracture.

This excess of hematoma or seroma can be removed by drains within the first few days after surgery or removed by local needle until the quality left in the abdomen, breast or thighs is decreased to around 75cc (10cc in the neck area).
When a hematoma is drained pure blood that may coagulate is obtained, while the draining of a seroma produces a bloody liquid that does not clot.

 Epidural Hematoma Information on Healthline
Epidural hematomas usually form when a violent blow breaks a blood vessel in the space outside the dura mater, whether in the skull or in the spinal column.
The growing hematoma pushes against the rigid bone of the skull or spinal column and thus exerts pressure on the dura mater, which in turn pushes on the brain or spinal cord.
Spinal epidural hematoma causes compression of the spinal cord.

 TheFetus.net - Subdural hematoma -Eric H. Dellinger, MD, Thomas C. Wheeler, MD
Autopsy demonstrated subdural hematomas in the left anterior and middle cranial fossae, compressing the left cerebral hemisphere (fig 2).
The differential diagnosis of a subdural hematoma includes subarachnoid hemorrhage, intraventricular hemorrhage, intracranial neoplasm, hydrocephalus, Dandy-Walker malformation, and miscellaneous cysts of the brain, including arachnoid cysts and an aneurysm of the vein of Galen.
The location of the subdural hematoma just beneath the cranium, the typical deformity of the brain, the layering of hemorrhagic material, and, occasionally, the patient history are most helpful in establishing the diagnosis.

 SUBCHORIONIC HEMATOMA IN THREATENED ABORTION:
In a study of 92 women with subchorionic hematoma evaluated with sonographic scan in King Khalid University Hospital, it was found that the mean ages and live births of patients who carried their pregnancies to viability were higher when compared with the patients who aborted.
It was concluded that subchorionic hematoma which appear either in the second trimester, or are larger, or located in the lower uterine segment, may be associated with higher rates of abortion or preterm deliveries.
Indeed, studies have shown that the impact of subchorionic hematoma on pregnancy depends in large measure on the amount of bleeding and the gestational age of the gravida.
