Hemicrania Continua-Like Headache due to Nonmetastatic Lung Cancer—A Vagal Cephalalgia
A 72-year-old man presented with a 7-week history of a new onset constant severe right-sided headache associated with redness and tearing of the right eye, which resolved on indomethacin due to nonmetastatic small cell carcinoma producing a large suprahilar mass. This is the first case report of a hemicrania continua-like headache with autonomic features due to lung cancer. I propose the term “vagal cephalalgia” to include headache and/or facial pain due to nonmetastatic lung cancer and cardiac cephalalgia which result from vagal afferent stimulation.
