A spinal cord ependymoma with syringomyelia is presented. The pathogenesis of syrinx formation, associated with intramedullary tumors is not fully understood. ⋯ Protein analysis of fluid specimens showed the fluid in tumor-associated syrinx to be an exudate. This strongly indicates that, in this case, intramedullary tumor-associated syringomyelia is based on disruption of the blood-brain barrier.

Case ReportsLumbar epidural lipomatosis causing neurogenic claudication in two obese patients.
Two obese patients suffering from neurogenic claudication caused by lumbar epidural lipomatosis are described. Although lumbar epidural lipomatosis is most often related to prolonged use of steroid drugs, obesity has also been reported as a possible cause. ⋯ Therefore weight reduction might be the initial therapy in an obese patient with symptomatic epidural lipomatosis. When weight reduction fails or when there are urgent clinical reasons, surgical removal of the excess amount of epidural fat should be considered.

Case ReportsCheiro-oral-pedal syndrome in the lesion of thalamocortical projections.
Unilateral sensory disturbance in the hand and mouth (cheiro-oral syndrome) is well known, but one in the hand, mouth and foot region (cheiro-oral-pedal syndrome) has been reported only in 2 patients with brainstem lesion and in 2 patients with thalamic infarction. We report the first case of cheiro-oral-pedal syndrome due to involvement of thalamocortical projections, which favors somatotopy in thalamocortical projections.

Case ReportsTransient unilateral hypoglossal nerve palsy: a case report.
Transient unilateral hypoglossal nerve palsy is very rare. We report an 81-year-old woman with right hypoglossal nerve palsy who recovered in 4 weeks without specific treatment. Extensive investigations did not disclose a cause for her hypoglossal nerve palsy. We believe that hypoglossal nerve palsy may sometimes be self-limited, just as Bell's palsy is.

Sensory disturbance around the corner of the mouth, in the palm of the hand and in the foot on the same side (cheiro-oral-pedal syndrome) has been reported only in 2 patients with brainstem lesion. We report 2 cases of cheiro-oral-pedal syndrome; the causative lesion was revealed by magnetic resonance imaging to be in the ventral postero-lateral and ventral posteromedial nuclei of the thalamus.
