Bath-Related Headache-The Second Case in South America

Bath-related headache (BRH) is a rare headache disorder described initially by Negoro et al. It is characterized by developing while the patient is bathing in hot water or immersion in a hot bath. We report a case a 63-year-old Brazilian woman who presented several episodes of intense throbbing headache that developed during a hot shower. Neurological examination and brain imaging showed no abnormality. The headache did not recur after the patient avoided bathing in hot water. Hot bath-related headache is a benign headache unassociated with a structural lesion.
