BackgroundIntracranial cerebrospinal fluid (CSF) volume depletion causes diverse clinical syndromes most of them constituting the manifestations of decreased intracranial pressure. Subdural collections or chronic subdural hematomas are the best-known consequences of persistent CSF leaks, especially in overshunted hydrocephalus. Continuous CSF escape also occurs after lumbar puncture, spinal anesthesia, and diverse spinal surgeries.Case DescriptionA 6-year-old boy submitted to reoperation of spinal cord compression due to partial sacral agenesis complained of postoperative orthostatic headaches and vomiting initially attributed to CSF hypotension. There were neither subcutaneous fluid accumulations nor CSF leakage from the wound. The child was treated with strict bed rest and intravenous hydration for 5 days. On reassuming orthostatism, the patient had syncope but did not hit his head. A cranial computerized tomography scan showed an acute subdural hematoma that was managed conservatively with total recovery.Discussion And ConclusionA review of current literature showed scanty reports of acute intracranial bleeding occurring after CSF depletion following spinal surgical procedures. To our knowledge, our reported patient represents the second case of this occurrence following surgery for closed spinal dysraphism in a child. The authors briefly review documented instances of acute subdural hematoma following spinal procedures, advise about its diagnosis, and suggest preventive measures.
