Clusterlike headache. A case of sphenoidal aspergilloma.

Clusterlike headaches secondary to structural disease have been described. Nevertheless, most of the reports antedate the International Headache Society classification and, indeed, only a few appear to fit its criteria for a diagnosis of cluster headache. We report here a case of sphenoidal sinus aspergilloma that fully complies with the criteria for cluster headache. This kind of lesion has never been described previously as a cause of a clusterlike headache.
