Intracranial hemorrhage; Axiali CT scan of a spontaneous intracranial hemorrhage: Specialty: Emergency medicine Symptoms: Same symptoms as ischemic stroke, but unconsciousness, headache, nausea, stiff neck, and seizures are more often in brain hemorrhages than ischemic strokes: Complications
In cases of aqueductal stenosis caused by tumor compression, a brain tumor in the region of the midbrain forms. More specific anatomically, a tumor forms in the pineal region which is dorsal to the midbrain and is level with the aqueduct of Sylvius. [2] As the tumor grows and expands, it compresses the aqueduct to eventually obstruct it.

Possible secondary causes of cerebral vasculitis are infections such as with varicella zoster virus (chicken pox or shingles), systemic auto-immune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis, medications and drugs (amphetamine, cocaine and heroin), some forms of cancer (lymphomas, leukemia and lung cancer) and ...
Meningioma seen at autopsy, as a tumor of the dura mater extending into the cranial cavity, and can be detached from the bone along with the rest of the dura mater. Small tumors (e.g., < 2.0 cm) usually are incidental findings at autopsy without having caused symptoms. Larger tumors may cause symptoms, depending on the size and location.
Seizures, including subclinical seizure activity, can complicate clinical courses and increase progression of brain herniation in persons with cerebral edema and increased intracranial pressure. [ 3 ] [ 39 ] Anticonvulsants can be used to treat seizures caused by acute brain injuries from a variety of origins. [ 3 ]
Moyamoya disease is a disease in which certain arteries in the brain are constricted. Blood flow is blocked by constriction and blood clots (). [2]A collateral circulation develops around the blocked vessels to compensate for the blockage, but the collateral vessels are small, weak, and prone to bleeding, aneurysm and thrombosis.
Atrial fibrillation causes blood clots to form within the heart, which may travel to the arteries within the brain and cause an embolism. The embolism prevents blood flow to the brain, which leads to a stroke. [26] An aneurysm is an abnormal bulging of small sections of arteries, which increases the risk of artery rupture.
