Sample item

A lesion of the right cerebellar hemisphere most likely causes which sign?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Right-sided limb ataxia

Cerebellar hemispheres coordinate ipsilateral limb movement through double-crossed pathways, so unilateral lesions produce ipsilateral ataxia, dysmetria, and intention tremor.

Option by option

  • A. Left facial paralysis

    Facial paralysis localizes to facial nerve or central facial pathways.

  • B. Left-sided spastic hemiparesis

    Spastic hemiparesis is a corticospinal tract sign.

  • C. Right homonymous hemianopia

    Homonymous field defects localize to retrochiasmal visual pathways.

  • D. Right-sided limb ataxia (correct)

    Correct. Cerebellar deficits are typically ipsilateral.
