• 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
