CT PATHOLOGY
Hemorrhages involving the basal ganglia area (the putamen in particular) tend to be non-traumatic and caused by hypertension, which damages and weakens the small penetrating arteries. A mass effect with midline shift, often with secondary edema, may lead to herniation.
A blood clot is seen over the external surface of the dura. Thus, this is an epidural hematoma. Such a location for hemorrhage is virtually always the result of trauma that causes a tear in the middle meningeal artery.
Another cause for hemorrhage, particularly in persons aged 10 to 30, is a vascular malformation. Seen here is a mass of irregular, tortuous vessels over the left posterior parietal region.
A thrombosis of the internal carotid artery is seen here. Arterial thromboses are far more common in the brain than venous thromboses (by a ratio of about 100 to 1).
