in weber syndrome , there is no mention of involvement of corticobulbar tract or c/l facial weakness ( refrence: haarisons principle of internal medicine 20th edition) . Can u please explain sir/mam ?
Sir one doubt please, u said in brown sequard syndrome cortico spinal tract will show signs ipsilaterally only. Then why here u said in mid brain disorders cortico spinal tract will cause C/L hemiplegia. Why not ipsilateral here also
Yes. Because in brown sequard syndrome, fibres are already crossed in medulla. If lesion is there in medulla, mostly uncrossed fibres are affected because pyramidal decussation occurs at lower medulla.
