Focal cortical @entity2045 and rolandic XXXX : clarification by magnetic resonance imaging.

@entity1 @entity410 @entity2045 @entity5 @entity1269 @entity75 @entity12198 @entity6795 @entity194 @entity302 @entity159
Focal cortical @entity2045 is rare. Obvious causes include @entity5 or @entity194 involving the motor strip, but in some cases no cause is apparent. We present 4 @entity1 who started to have focal @entity2045 in childhood. All had focal motor @entity410 as well, and one had recurrent focal motor @entity159 . All 4 had a mild progressive @entity1269 . Electrographic investigations showed focal @entity302 discharges in the contralateral rolandic areas. Radiological studies were unrevealing, but magnetic resonance showed @entity75 in 3 @entity1 . At surgery, abnormally wide gyri were found in the distribution demonstrated by magnetic resonance. The pathological substrate was focal @entity6795 . All @entity1 have improved considerably following surgery. These findings suggest that focal @entity2045 may be due to a rolandic @entity12198 . Visualization of these lesions by magnetic resonance permits development of a surgical strategy leading to optimal treatment of these medically intractable @entity302 .
