3. • Fig SK 5-1 Meningioma. Huge hyperdense
mass in the frontal lobe.

4. • Fig SK 5-2 Meningioma. Bilateral hyperdense
masses (arrows) in juxtadural locations.

5. • Fig SK 5-3 Metastasis. Nonenhanced scan
shows a hyperdense mass (arrow) in the right
frontal region representing a metastasis from
carcinoma of the lung.

6. • Fig SK 5-4 Primary lymphoma. Multifocal
hyperdense masses (arrows).

7. • Fig SK 5-5 Intracerebral hematoma. Large,
homogeneous high-density area with extensive
acute bleeding into the lateral ventricles.

8. • Fig SK 5-6 Acute epidural hematoma. CT scan of a 4-year-
old child involved in a motor vehicle accident shows a
characteristic lens-shaped epidural hematoma (open
arrows). The substantial mass effect associated with the
hematoma distorts the lateral ventricle (closed arrow).

9. Fig SK 5-7 Epidural hematoma. Bilaterally symmetric posterior
high-density areas (arrows) with lens-shaped configurations.

10. • Fig SK 5-8 Acute subdural hematoma. High-density,
crescent-shaped lesion (open arrow) adjacent to the
inner table of the skull. The hematoma extends into
the interhemispheric fissure (closed arrowhead).
