SAH affects 6-9 people per 100,000 of the population per year and constitutes about 6% of first strokes. An apparent decrease from older published figures is attributed to a higher rate of CT scanning, excluding other haemorrhagic causes. Approximately 85% of patients bleed from intracranial arterial aneurysms, 10% from a non-aneurysmal peri-mesencephalic haemorrhage and 5% from other vascular ...

A case of haemorrhage into a parasagittal meningioma treated by surgical resection is presented. A review of the literature found 43 additional cases of meningioma associated with haemorrhage. By correlating these cases with those from another large series of meningiomas classified by histological type and location, an estimation of the "relative bleeding tendency" of certain classes of meningi...

Twenty newborn infants with clinically apparent intraventricular haemorrhage were studied in order to determine the factors associated with mortality and morbidity. Ten survived, 4 without handicap and 2 with only moderate handicap. Maturity and not size of haemorrhage appeared to be the main factor affecting mortality and morbidity at 1 year. Coma longer than 24 hours after intraventricular ha...

Ruptured hydatid cysts are rare causes of intra-abdominal haemorrhage. They are usually secondary to primary hepatic hydatid disease. They are even rarer causes of intra-abdominal haemorrhage in pregnancy. Untreated cases or cases with delayed diagnoses are associated with a poor outcome due to systemic hypotension and secondary organ damage resulting from exsanguinating haemorrhage. Ultrasound...

Subarachnoid haemorrhage accounts for only 5% of strokes, but occurs at a fairly young age. Sudden headache is the cardinal feature, but patients might not report the mode of onset. CT brain scanning is normal in most patients with sudden headache, but to exclude subarachnoid haemorrhage or other serious disorders, a carefully planned lumbar puncture is also needed. Aneurysms are the cause of s...

The great majority of acute brain injury results from trauma or from disorders of the cerebrovasculature, i.e. ischaemic stroke or haemorrhage. These injuries are characterized by an initial insult that triggers a cascade of injurious cellular processes. The nature of these processes in spontaneous intracranial haemorrhage is poorly understood. Subarachnoid haemorrhage, a particularly deadly fo...
