Spontaneous Intracranial Hypotension, a Possible Cause of Chronic Subdural Hematoma

Although spontaneous intracranial hypotension were previously thought to be rare, they are now documented with increasing incidence by work up using advanced imaging techniques. We report our experience of CSF hypovolemia syndrome presented with chronic subdural hematoma on 37-years old young adult who had no traumatic history. Even spontaneous intracranial hypotension is not rare but it remains misdiagnosed. Causes of chronic subdural hematoma is generally trauma, but we need to consider this etiology of possible cause of chronic subdural hematoma , especially if young adult who had no trauma history complainted head ache and there was chronic subdural hematoma on brain CT.
