• Fig SK 22-1 Cryptococcal meningitis in AIDS.
Meningeal enhancement along the cerebral
peduncles (arrowheads).
• Fig SK 22-2 Cysticercosis. Subarachnoid
enhancement in the basal cisterns and left
sylvian fissure.38
• Fig SK 22-3 Meningeal carcinomatosis.
Enhancement around the midbrain and cerebral
peduncles represents pial spread of tumor.38
• Fig SK 22-4 Lymphoma. (A) Sagittal and (B)
coronal scans show enhancement of the falx
cerebri as well as about the convexity and at
the base of the temporal lobes.38
• Fig SK 22-5 Neurosarcoidosis. (A) Unenhanced
image reveals no parenchymal or meningeal
abnormalities. (B) An enhanced scan shows
diffuse leptomeningeal involvement.38
