3. • Fig SK 11-1 Intracranial hemorrhage. (A)
Increased signal in the left basal ganglion. (B)
Unenhanced CT shows slightly increased
attenuation in the same region.23

4. • Fig SK 11-2 Petechial hemorrhagic infarct.
Increased signal in the right basal ganglion
(straight arrows) and temporal area (curved
arrows).23

5. • Fig SK 11-3 Parenteral nutrition. Increased signal intensity in the globus pallidus
(arrows).23

6. • Fig SK 11-4 Calcification (hypoparathyroidism). (A)
Unenhanced CT scan shows extensive calcification in
the basal ganglia (arrows) and subcortical white matter
(arrowheads) bilaterally. (B) T1-weighted MR image
shows increased signal intensity in the basal ganglia.23

7. • Fig SK 11-5 Neurofibromatosis. (A) T1-weighted image
shows hyperintensity involving the globus pallidus and
internal capsule (arrowheads) bilaterally. (B) On the
corresponding T2-weighted image, there are small
nodular foci of increased intensity in the globus
pallidus and internal capsule bilaterally, but the extent
and morphology of the signal abnormality differ from
those on the T1-weighted image.23

8. • Fig SK 11-6 Hypoxic ischemic encephalopathy.
Hyperintense foci in the basal ganglia bilaterally
and laminar hyperintensity along the cerebral
cortex (arrows) that is more prominent in the
parieto-occipital region.23

9. • Fig SK 11-7 Chronic hepatic failure. Increased
signal intensity in the globus pallidus
(arrows).23

10. • Fig SK 11-8 Diabetic hyperglycemia. Increased
signal intensity in the left putamen (arrow). The
patient had an abrupt onset of involuntary
movements involving the right limbs.23

11. • Fig SK 11-9 Japanese encephalitis. (A) Axial T1-weighted image
shows increased signal intensity suggestive of subacute
hemorrhage in the thalamus (solid arrows) and corpus striatum
(open arrows) bilaterally. (B) On a coronal T1-weighted image, there
is increased signal intensity in the corpus striatum (open arrows),
thalamus (short arrows), and cerebral peduncle (long arrows)
bilaterally, as well as in the right hippocampus (arrowhead).23
