Intramuscular hematoma at buttocks as a result of a sports injury Left to right: Epidural, subdural, and intracranial hematoma of the brain Hematoma of the ankle caused by a 3rd degree sprain. Subdermal hematoma (under the skin) Intramuscular hematoma (inside muscle tissue) Skull/brain: Subgaleal hematoma – between the galea aponeurosis and ...
Subdural hematomas may cause an increase in the pressure inside the skull, which in turn can cause compression of and damage to delicate brain tissue. Acute subdural hematomas are often life-threatening. Chronic subdural hematomas have a better prognosis if properly managed
As a type of hematoma, a bruise is always caused by internal bleeding into the interstitial tissues which does not break through the skin, usually initiated by blunt trauma, which causes damage through physical compression and deceleration forces. Trauma sufficient to cause bruising can occur from a wide variety of situations including ...
A "heat hematoma" is an epidural hematoma caused by severe thermal burn, causing contraction and exfoliation of the dura mater and exfoliate from the skull, in turn causing exudation of blood from the venous sinuses. [13] The hematoma can be seen on autopsy as brick red, or as radiolucent on CT scan, because of heat-induced coagulation of the ...
Most subdural hygromas are believed to be derived from chronic subdural hematomas. They are commonly seen in elderly people after minor trauma but can also be seen in children following infection or trauma. One of the common causes of subdural hygroma is a sudden decrease in pressure as a result of placing a ventricular shunt.
An untreated septal hematoma may lead to the destruction of the septum and immediate drainage is necessary. Untimely diagnosis and/or treatment of septal hematomas can cause what is called a saddle nose deformity. [4] This condition is more common in children because the septum is thicker and the lining more flexible. [5]
When the epidural hematoma is large enough, it will cause mass effect on contralateral brain which lead to midline, subfalcine (below the falx cerebri), and trans-tentorial (crossing tentorium cerebelli) herniations. This phenomenon can cause the subject to lose consciousness and eventually to death. [3]
Caused by shearing injuries at the time of impact, these contusions occur especially at the junction between grey and white matter and in the upper brain stem, basal ganglia, thalamus and areas near the third ventricle. [14] The hemorrhages can occur as the result of brain herniation, which can cause arteries to tear and bleed. [14]
