Benedicts' syndrome-- lesion in midbrain ventral and tegmentum affecting CTS,IIIn, red nucleus, cerebellothalamic fibers leads to contralateral weakness, facial weakness, ipsilateral abducens, chorea
Millard Gubler-- medial pons affects VI n, and CST get ipsilateral VI n. paresis and contralateral HP
Foville's -- dorsal pons , above with extension into tegmentum, affects PPRF get ipsilateral facial paresis, conjugate gaze paresis also
Weber's- medial midbrain. ipsilateral IIIn and cerebral peduncle with HP
Claude's- midbrain and dorsal tegmentum-- ipsilateral IIIn, red nucleus HP + ataxia contralateral (pupil dilated, and eye is down and out)
Raymond Cestan s-- ventral pons- CST + MLF produces INO, contralateral HP and loss adduction side of lesion
