Delayed-onset post-traumatic headache after a motor vehicle collision: a case report.
BACKGROUND
Headaches are common after a motor vehicle accident (MVA). Post-traumatic headaches share many clinical symptoms including the clinical course of primary headaches. Secondary headaches (including those resulting from a subdural hematoma) are not as common, but should be considered in cases of post-traumatic events particularly if clinical symptoms progress.


METHODS
A case of a patient with a post-traumatic subdural hematoma demonstrates the importance of carefully examining, properly diagnosing and managing patients that experience headaches after MVAs. This patient presented with uncomplicated low back pain, neck pain and headache which progressed at one month to include focal neurological deficits. Since clinical examination alone may not be sufficient to diagnose secondary headaches, immediate referral to the emergency department may be required.


CONCLUSIONS
Primary contact practitioners should be aware of the various causes of headaches that result after a MVA. Headaches, which do not respond or progress, should be followed aggressively to determine their source.
