A hypothalamic stroke producing recurrent hemihyperhidrosis.
A 40-year-old man awoke with exuberant sustained sweating of the entire left side of the body, which became intermittent over the next few days. MRI indicated a single linear hyperintensity in the right posterior hypothalamus, diminishing on a repeat scan. He continues to have episodes of left unilateral sweating precipitated by exercise or minor infection.
