Spontaneous Vertebral Artery Dissection with Anti-cardiolipin Antibody Positivity.

A 29-year-old woman with no medical history visited our hospital with a sudden onset of headache. Magnetic resonance imaging and angiography of the head and neck demonstrated an occlusion and intramural hematoma in the right vertebral artery. We diagnosed vertebral artery dissection and provided treatment to reduce her headache and control her blood pressure. The patient's symptoms and imaging findings gradually improved. Blood biochemistry was positive for anticardiolipin antibodies. Anticardiolipin antibodies are often associated with thromboembolism but rarely associated with the development of arterial dissection in the cerebral artery. We present a case of vertebral arterial dissection and anticardiolipin antibody positivity along with a discussion of the related literature.
