%X A 19-year-old male suffered sequential acute ischemic cerebral infarctions in the vertebrobasilar arterial territory, each episode following rigorous exercise with frequent head turning. Angiography revealed a nonocclusive left vertebral artery (VA) dissection near the transverse foramina of C2 (Figure 1A and A¡ä) and complete occlusion of the left VA at that level with rightward head turn (Figure 1B). The patient was placed in a rigid cervical collar and treated with enoxaparin. Repeat angiography after 3 months showed resolution of the arterial dissection but persistent compression of the left VA with rightward head turn. The patient underwent elective surgical decompression of the left VA, where his neck muscles were found to be hypertrophied. Bow Hunter¡¯s syndrome (BHS) refers to mechanical occlusion of the VA during head rotation secondary to numerous etiologies including congenital or acquired bony malformations or neck muscle hypertrophy.1 Unrecognized BHS may result in recurrent infarctions, but with decompression surgery can, as in this case, carry an excellent prognosis.
