Rapid resolution of signs of primary intracerebral haemorrhage in computed tomograms of the brain.

Computed tomography of the brain plays an important part in the management of stroke, both in those cases in which diagnosis is uncertain' and to differentiate haemorrhagic from ischaemic stroke. Although deciding which type of stroke is present may not affect the management of many patients, it is important if treatment with anticoagulants or carotid surgery is being considered. When such treatment is being considered it is vital that patients with primary intracerebral haemorrhage are correctly identified as anticoagulation is dangerous and carotid endarterectomy inappropriate. It may also be advisable to exclude primary intracerebral haemorrhage before treatment with aspirin is started, although whether aspirin predisposes to extension of the stroke or recurrence in cases of primary intracerebral haemorrhage is not known.
