Bilateral subdural hemorrhage following lumbar puncture in a case of suspected meningitis. A case report.

Intracranial subdural hemorrhage is a rare complication of lumbar puncture. Caudal traction and tear of the subdural veins due to negative pressure caused by leakage of cerebrospinal fluid (CSF) following lumbar puncture (LP) is the mechanism. Prolonged headache or neurological symptoms following LP should warrant cross-sectional imaging to rule out subdural hemorrhage as it can be fatal. We report a case of subdural hemorrhage following LP in a patient with suspected meningitis and communicating hydrocephalus.
