<bold>FIGURE 61-5</bold> <bold>Contrasted computerized tomography scan of a patient with left occipital brain abscess.</bold> The necrotic material in the abscess center appears dark (hypodense). The white rim surrounding the abscess is its wall, which is visualized because of its vascularization and contiguous vasodilation. There is surrounding hypodensity, representing edema.

<bold>Fig SK 6-10. Brain abscess.</bold> (A) Nonenhanced CT scan shows vasogenic edema in the right anterior parietal white matter. The isodense ring of the abscess capsule can be seen (white arrow). (B) Contrast-enhanced study shows a thick but uniformly enhancing capsule with the beginnings of a daughter abscess anteriorly (arrow). The enhancement of an abscess is typically circular and nearly uniform except along the medial surface.<sup>11</sup>
