[Hansen's neuritis in the form of pseudysyringomyelia. Clinical, diagnostic and therapeutic consideration a propos of 3 cases]. / Névrite hansénienne à forme pseudosyringomyélique. Considérations cliniques, diagnostiques et thérapeutiques à propos de trois cas

Three cases of neuropathic leprosy (one Moroccan, two non-colonial immigrants) enable attention to be drawn to two aspects of theproblem of Hansen's neuritis: 1) such cases should no longer be considered exceptional, infection occuring in countries where leprosy is endemic but the disease developing years later in any country; 2) among the various neurological aspects of neuritis due to Hansen's bacillus, great stress is laid on sensory disorders of the syringomyelic type, with thermalgesic dissociation; although these symptoms have been considered typical (our three cases are an illustration of this), they seem to occur fairly rarely and are the cause of difficulties in diagnosis as it is the last thing one would think of. Treatment of these neural forms is not encouraging, in spite of a therapeutic arsenal which in theory is considered effective.
