Neurology current issue
A 61-year-old man presented with orthostatic headaches and asymmetric sensorineural hearing loss (ASNHL) 8 years after cervical laminoplasty. Percussion of his cervical spine elicited Lhermitte sign.

CT myelogram revealed fractured hardware puncturing adjacent dura with resultant CSF leak (figure 2).
