ABSTRACT
The purpose of this case report is to describe chronic encapsulated intracerebral hematoma (CEIH), a rare and not fully understood brain lesion. The differentiation from chronic cerebral hematoma, cerebral abscess, and intra-axial tumor is based on clinical and imaging criteria. The diagnosis is confirmed by histological analysis. In the English medical literature, we found 39 patients reported with this lesion. The key feature is the formation of a capsule between a hematoma and cerebral parenchyma. The reasons for this formation are not known. In our patient, an arteriovenous malformation was located outside but adjacent to the CEIH.

To overcome the donor shortage, any potential donor resource must be detected. By establishing a professional service for peripheral hospitals, the numbers of donors available in small hospitals could be nearly doubled: 85% of all donors in our region come from nonuniversity hospitals. By using total quality management techniques, the time requirements for organ donation after confirmation of brain-death and given consent could be reduced to 6 h.

The texture-based segmentation of x-ray images of focal bone lesions using topological maps is introduced. Texture characteristics are described by image-point correlation of feature images to feature vectors. For the segmentation, the topological map is labeled using an improved labeling strategy. Results of the technique are demonstrated on original and synthetic x-ray images and quantified with the aid of quality measures. In addition, a classifier-specific contribution analysis is applied for assessing the feature area.
