Evaluation of intracerebral hematoma by computed tomography

The CT scan appearances of acute intracerebral hematoma are usually diagnostic, and can be differentiated from hemorrhagic tumor and infarction. Some prognostic evaluations can be made, depending on the site and size of the hemorrhage. Sequential studies indicate resolution of the density of the hematoma over a period of approximately six weeks. This however does not appear to correlate with pathological resolution, but does reflect the hemoglobin concentration in the hematoma. Angiography is indicated when an underlying AVM or aneurysm is suspected, whereas contrast infusion studies are not of great value in detecting these lesions.
