We report a case of Horner's syndrome due to ipsilateral posterior
hypothalamic infarction, occurring in the absence of other signs of
hypothalamic dysfunction. Associated symptoms of contralateral
faciobrachial weakness and dysarthria correlated with the extension of the
infarct into the posterior limb of the internal capsule seen by magnetic
resonance imaging. The likely vascular anatomy of this lesion is discussed.
