Background Dissection of a fenestration of the vertebral artery is extremely rare. CASE REPORTS A 55‐year‐old man presented with severe headache. Radiological examinations revealed a fenestration of the intracranial vertebral artery, and both limbs of the fenestration showed stenosis and dilatation. Three‐dimensional‐T1 fat suppression‐weighted images of magnetic resonance imaging (MRI) showed an intramural thrombus. These findings indicated that dissection occurred in both limbs of the fenestrated vertebral artery. Since no hemorrhage or infarction was observed, the patient was conservatively treated with an anti‐hypertensive drug. His symptom gradually improved and finally disappeared. Follow‐up MRI in the 2nd month showed a decreased intramural thrombus and smoothened vertebral artery. Discussion Detection of an intramural thrombus on MRI is useful for the diagnosis of dissection of a vertebral artery fenestration. Treatment of this rare condition might be the same as that for a non‐fenestrated vertebral artery.
