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

Abstract
In cases of primary intracerebral haemorrhage the characteristic high density lesion seen on computed tomography may resolve rapidly, so that within two weeks of stroke the radiological appearance may resemble that of cerebral infarction. If treatment with anticoagulants, carotid endarterectomy, or aspirin is being considered computed tomography should be performed within two weeks of the stroke. Failing this, the radiologist should be alerted to the delay to avoid misleading reports such as "consistent with cerebral infarct" being issued when the computed tomogram is equally consistent with primary intracerebral haemorrhage.
