Regarding involvement of structures in Weber syndrome all true except:: (A) Oculomotor nerve roots, (B) Cerebellar peduncles, (C) Corticobulbar tracts, (D) Cortispinal tract
Answer is B. Ref. API Textbook of Medicine. Pg. 533
 
Weber's Syndrome constitutes an ipsilateral third nerve paralysis with a contralateral hemiplegia.

It is due to a lesion in one half of the midbrain e.g. as a result of occlusion of the paramedian branches of the basilar artery.
If there is a localised lesion in the region of the red nucleus, then there is paralysis of upward gaze.
