Orthostatic headache as the presenting symptom of cervical spine metastasis

Orthostatic headache is a key symptom of intracranial hypotension; however, not all orthostatic headaches are caused by cerebrospinal fluid leaks leading to intracranial hypotension. We report here the unusual case of a 68-year-old man presenting with orthostatic headache in which compression of the C3 spinal nerve root by metastatic tumor invasion may contribute to the development of his orthostatic headache.
