Chronic subdural hematoma: correlation of computerized tomography with colour.

The computerized tomographic and operative findings in 10 patients with chronic subdural hematoma (SDH) are reviewed. A constant correlation was found between the CT density and the colour of the hematoma evacuated thus enabling an accurate prediction of the colour of fluid one would expect to find at operation. Certain clinical features and CT appearances are highlighted to prevent the likelihood of misdiagnoses.
