[Cranial pachymeningitis of unknown origin. Study of 3 cases].
The clinical picture in three cases of chronic cranial pachymeningitis of unknown origin was dominated by headache, disturbed balance, a confusional state and cranial nerve lesions. The erythrocyte sedimentation rate was increased and the CSF showed inflammatory changes. CT scan imaging showed thickening of the tentorium cerebelli, which took up contrast intensely. Meningeal biopsy showed the dura-mater to be the site of a non-specific inflammatory process. No precise cause was found. Clinical manifestations in these three patients were remarkably corticosensitive but lesions did not regress on CT. The development of a state of corticodependence led to an attempt at treatment with radiotherapy and/or azathioprine, but follow up is insufficient to evaluate results.
