Besides, intracranial hemorrhage that are atypical for trauma should also be investigated further with CT or MR angiography to look for other causes of intracranial bleeds apart from trauma causes. Such atypical patterns includes: isolated SAH in the basal cisterns , isolated large-volume SAH in the Sylvian fissure , and isolated SAH in the ...
This is often a result of secondary injury, which can damage neurons that were unharmed in the primary injury. It occurs after a variety of brain injury including subarachnoid hemorrhage, stroke, and traumatic brain injury and involves metabolic cascades. [13] Secondary injury can result from complications of the injury. [1]
Causes: Head injury, bleeding disorder, blood vessel malformation [1] Diagnostic method: Medical imaging (CT scan) [1] Differential diagnosis: Subdural hematoma, subarachnoid hemorrhage, traumatic brain injury, [1] transient ischemic attack seizure, intracranial abscess, brain tumor [3] Treatment: Surgery (craniotomy, burr hole) [1]
Subarachnoid haemorrhage occurs when blood leaks out of damaged vessels into the cerebrospinal fluid in the subarachnoid space around the brain. [2] The most common cause of a subarachnoid hemorrhage is an aneurysm rupture due to the weakened blood vessel walls and increased wall stress. [ 48 ]
The underlying pathology originates in the brain and usually involves an intracranial hemorrhage, such as a subarachnoid hemorrhage (SAH), or several types of elevated intracranial pressure. The abrupt increase in intracranial pressure causes the condition, which is then communicated to the eyes through the optic nerve sheath.
Intraventricular hemorrhage (IVH), also known as intraventricular bleeding, is a bleeding into the brain's ventricular system, where the cerebrospinal fluid is produced and circulates through towards the subarachnoid space. It can result from physical trauma or from hemorrhagic stroke.
Diagnosis typically involves imaging techniques such as CT or MR angiography and lumbar puncture to detect subarachnoid hemorrhage. Prognosis depends on factors like the size and location of the aneurysm and the patient’s age and health, with larger aneurysms having a higher risk of rupture and poorer outcomes.
