title: [A unusual manifestation of multiple sclerosis: sciatica].
abstract: The authors recall the possibility of a typical sciatica in multiple sclerosis and describe seven new cases. Their main clinical features are: early onset before any other signs of the disease, hyperalgic, paroxysmal, short, repetitive episodes, absence of mechanical or effort triggers, absence of improvement with rest or anti-inflammatory drugs, well defined course. The intra-medullar origin of these attacks is suggested by the clinical criteria and the aspect of evoked potentials of the lower limbs recorded in 2 of the 7 patients.
