What is Convexal subarachnoid hemorrhage?

What is Convexal subarachnoid hemorrhage?

Convexal subarachnoid hemorrhages (cSAH) are non-traumatic intracranial hemorrhages that occur within the surface sulci of the brain (cf. basal cisternal distribution of aneurysmal SAH).

What is Perimesencephalic subarachnoid hemorrhage?

Perimesencephalic subarachnoid hemorrhage (PMSAH) is a distinct pattern of subarachnoid hemorrhage (SAH), which is centered on the basal cisterns around the midbrain.

What is cortical subarachnoid hemorrhage?

Abstract. Objective: Isolated, non-traumatic, cortical subarachnoid haemorrhage (cSAH) is a rare type of cerebrovascular disease caused by various disorders. In a few cases, especially in the elderly, no apparent cause can be identified. We report a case series of patients without apparent cause of cSAH.

What is the best modality for the diagnosis of subarachnoid bleeding?

To diagnose a subarachnoid hemorrhage, your doctor is likely to recommend: CT scan. This imaging test can detect bleeding in your brain. Your doctor may inject a contrast dye to view your blood vessels in greater detail (CT angiogram).

What is Call Fleming Syndrome?

Call–Fleming syndrome describes a rare, reversible segmental vasoconstriction of cerebral arteries that symptomatically presents with a thunderclap head- ache followed by focal neurologic deficits most com- monly in women aged 20 to 50 years.

What is cerebral amyloid angiopathy?

Cerebral amyloid angiopathy (CAA) is a condition in which proteins called amyloid build up on the walls of the arteries in the brain. CAA increases the risk for stroke caused by bleeding and dementia.

What are Perimesencephalic cisterns?

The perimesencephalic cisterns include the interpeduncular, crural, ambient, and quadrigeminal cisterns surrounding the midbrain. The interpeduncular cistern lies between the cerebral peduncles. The crural cistern lies between the posterior segment of the uncus and the cerebral peduncle.

What is the most common cause of intracerebral hemorrhage?

ICH is most commonly caused by hypertension, arteriovenous malformations, or head trauma. Treatment focuses on stopping the bleeding, removing the blood clot (hematoma), and relieving the pressure on the brain.
