[Recurrent and relapsing course of borreliosis of the nervous system].

The clinical variability of chronic infections due to Borrelia burgdorferi is greater than previously thought. Three personal cases are presented in an overview, together with cases from the literature. Chronic spastic para- and quadriparesis, transverse myelitis and recurrent hemiparesis have been noted in such cases.

[Primary chronic neurobrucellosis].

Brucellosis involving the nervous system usually shows meningomyelitis and/or radiculoneuritis and can by their clinical appearance not be differentiated from other chronic proliferative diseases of the nervous system. Sporadic cases can only be suspected on clinical grounds if a previous exposition is known. The cerebrospinal fluid showing a proliferative or granulomatous cytological picture is strongly suggestive of the diagnosis, which is confirmed by two rising titer values in the complement binding reaction for Brucella-specific antigen.

Topological characteristics of brainstem lesions in clinically definite and clinically probable cases of multiple sclerosis: an MRI-study.

Disseminated lesions in the white matter of the cerebral hemispheres and confluent lesions at the borders of the lateral ventricles as seen on MRI are both considered acceptable paraclinical evidence for the diagnosis of multiple sclerosis. Similar changes are, however, also found in vascular diseases of the brain. We therefore aimed at identifying those additional traits in the infratentorial region, which in our experience are not frequently found in cerebrovascular pathology.
