• Fig SK 16-1 Glioma. Poorly defined low-attenuation mass causing irregular expansion of the brainstem and compression of the fourth ventricle.
• Fig SK 16-2 Metastasis. Subtle, ill-defined area of low density (arrow).
• Fig SK 16-3 Infarction. Central low-attenuation region (arrow).
• Fig SK 16-4 Central pontine myelinolysis. Low-attenuation region (arrows) in the center of the pons in a comatose alcoholic patient. Note the widening of the prepontine subarachnoid space, indicating loss of brainstem volume due to atrophy.
• Fig SK 16-5 Syringobulbia. Well-demarcated mass of cerebrospinal fluid density (arrow) in the center of the brainstem.
