Long-term evolution of a laughing headache associated with Chiari type 1 malformation.
We describe an acute-onset, sharp, short-lasting (few seconds) headache at the vertex, that first occurred 10 years ago in a 44-year-old woman. Attacks were triggered by vigorous laughing. A magnetic resonance imaging study showed a Chiari type 1 malformation. To our knowledge, laugh-induced headache with long-term evolution in association with Chiari type 1 malformation has not been previously reported.
