Intracranial subdural hematoma after puncture of spinal meningeal cysts.
A patient is reported with an intracranial subdural hematoma after puncture of spinal meningeal cysts. In this case, spinal meningeal cysts were diagnosed by myelography. No intracranial subdural hematoma was detected immediately after myelography. Deterioration in the patient's level of consciousness occurred after puncture of the cysts. The authors speculated that the cerebrospinal fluid pressure dropped rapidly when the spinal meningeal cysts were punctured. This displaced the cerebral bridging veins downward, tearing them and resulting in an intracranial subdural hematoma.
