Although trauma is the most common cause of ICH, ICH can develop from nontraumatic etiologies. Hypertensive damage to blood vessel walls (eg, hypertension, eclampsia, drug abuse) is the most common cause of nontraumatic ICH. Other, less common nontraumatic causes of ICH include:
Autoregulatory dysfunction with excessive cerebral blood flow (eg, reperfusion injury, hemorrhagic transformation, cold exposure)
Altered hemostasis (eg, thrombolysis, anticoagulation, bleeding diathesis)
Hemorrhagic necrosis (eg, tumor, infection)
Venous outflow obstruction (eg, cerebral venous thrombosis)
