Bilateral Subdural Hematomas Following Routine Lumbar Diskectomy
Intracranial hypotension is a rare, and possibly underrecognized, cause of headache in middle age. Occurring spontaneously in the vast majority of cases, it has been occasionally reported after certain neurosurgical procedures involving craniectomy. We report a unique situation in which a patient developed severe postural headache typical of intracranial hypotension, which was complicated by bilateral subdural hematomas, immediately following a routine lumbar diskectomy; the headache resolved spontaneously. We suggest that an intraoperative microscopic dural breach was the site of sustained, but self-limited, cerebrospinal fluid leakage that eventually led to intracranial hypotension.
