title: [Differential-diagnostic problems with the brain abscess in axial computerized tomography (author's transl)].
abstract: On the base of three autoptically controlled cases with ring-shaped findings in the CT the problem of the differential diagnosis of the brain abscess in axial computerized tomography is discussed. A brain abscess must especially be taken into account when the hyperdense anulus already occurs without enhancement by contrast media. The ring-shaped finding is then caused by the high amount of collagen fibres within the abscess membrane, which has no comparable correlate in other focal processes of the brain.
