I came across this paragraph at the web site listed below. I had a CT once for other reasons but never an MRI. Just another "thought in the dark."
"... I recommend that all patients felt to have cluster headaches, or *CPH (see below), have a magnetic resonance image (MRI) of the head to exclude the rare presence of a benign tumor inducing cluster-like headaches. These are most likely to be located in the vicinity of the internal carotid artery. Computed tomography (CT) scans do not reliably show tumors in this region."
