SYNOPSIS For seventeen years, a young man suffered from headaches of one to three days duration occurring once every six or seven days and totally disappearing between episodes. These were strictly unilateral (always on the left side), and were absolutely responsive to indomethacin. They differ clinically from the other two indomethacin‐responsive headaches described up to now: Hemicrania Continua (HC) and Chronic Paroxysmal Hemicrania (CPH). He has a sister suffering from HC. Similar to HC, but unlike CPH, topical tyramine in our patient's eyes resulted in anisocoria before, but not after, indomethacin treatment. Our case differs from HC, however, in its time pattern; it could either be a pre‐chronic stage of HC or a new type of headache. it seems unlikely that a time pattern that has remained unchanged for 17 years will become continuous, as in HC, in the future, and thus it is possible that our patient represents a case of a new type of headache that we propose to name “Hemicrania Episodica.” In any case, it seems probable that this type of headache, although clinically different, may share a common pathogenic basis with HC.
