The computed tomographic findings of peritentorial subdural hemorrhage.

The computed tomographic (CT) findings in six cases of subdural hemorrhage in the peritentorial region are listed and discussed. The CT appearance of peritentorial subdural hemorrhage sometimes mimicks that of intra-axial lesions, but coronal scanning or reconstruction can be used to resolve this problem. Awareness of this unusual location for subdural hemorrhage is helpful in providing an accurate preoperative diagnosis.
