The authors report a case of subarachnoid hemorrhage and spinal root injury caused by an acupuncture needle buried in the posterior neck about 30 years before onset. A 33-year-old female presented with sudden onset of severe occipital headaches. Plain x-ray films of the cervical spine revealed a fine gold needle, about 1.5 cm in length, between the C1 and C2 vertebrae. The needle was piercing the spinal nerve root through the dural vein, and was removed. Postoperatively, the pain exacerbated by neck movement disappeared.
