Abstract

We describe an original case of cluster-like headache CLH) revealing a parasagittal tumor invading the superior sagittal sinus (SSS). Resection of the tumor (hemangiopericytoma) allowed the re-permeabilization of the SSS and was followed by the complete disappearance of CLH. Several mechanisms including obstruction of the SSS, hypervascularization with arterio-veinous shunt, and overflow in the cavernous sinus might explain the symptoms.
