'Head banging' during rock show causing subdural hematoma.

wasp or insect stings in the past (which would have hypothetically favored a hypersensitivity reaction). In this case, the proximity of the sting (on the eyelid) to the CNS may have been a factor in causing the elevated CSF pressures as a result of intracranial inflammation due to the potentially neurotoxic wasp venom. No other cause for the elevated CSF pressures could be found (our patient was not on any oral contraceptive pills) and resolution of the intracranial hypertension occurred spontaneously and within the expected time frame, suggesting a temporal correlation between the cause (wasp sting) and the event (raised intracranial pressure). Insect stings are generally regarded as benign, but it is worth remembering that in some cases, as in this one, venom intoxication may be responsible for some unusual clinical manifestations.
