  eMJA: Inhaled corticosteroids, adrenal suppression and benign intracranial hypertension
Benign intracranial hypertension was diagnosed and he was prescribed oral acetazolamide (250 mg four times daily).
Given the absence of papilloedema at presentation, and the fact that the headache and elevated CSF opening pressure were clearly temporally associated with the withdrawal of inhaled corticosteroids, we suggest that the benign intracranial hypertension was related to the withdrawal of the steroid dose.
Benign intracranial hypertension has previously only been reported in cases of primary adrenal insufficiency (Addison disease),6 or in association with the use or withdrawal of topical, oral or intranasal corticosteroids.

Historically BIH was referred to, as brain swelling of unknown cause, otitic or toxic hydrocephalus, pseudoabscess, hypertensive meningela hydrops or serous meningitis (Quincke, 1897).
Because of the different pathophysiology and prognosis BIH is considered separate from conditions producing symptoms identical to benign intracranial hypertension, such as chronic meningoencephalitis venous sinus thrombophlebitis, congestive intrathoracic lesions, polyradiculitis and spinal cord tumors.

 Benign intracranial hypertension
Idiopathic intracranial hypertension (IIH), sometimes called benign intracranial hypertension (BIH) or pseudotumor cerebri (PTC) is a neurological disorder that is characterized by increased intracranial pressure (ICP), in the absence of a tumor or other intracranial pathology.
The terms "benign" and "pseudotumor" have often been used for this disorder to make clear that the increased ICP is not caused by a tumor or malignancy.
In cases of severe obesity, some clinicians advocate the use of gastric bypass surgery, though the efficacy of this procedure in the treatment of IIH is not fully established.

 Idiopathic intracranial hypertension within the ICF model
Because "pseudo" and "benign" connote a trivial sort of diagnosis, clinicians are currently supporting the name idiopathic intracranial hypertension (Corbett, 2000).
Confusion about the name of the disease stems from the fact that there are two forms of intracranial hypertension: primary, or idiopathic, intracranial hypertension, in which increased intracranial pressure (ICP) occurs spontaneously, without a known cause, and secondary intracranial hypertension, which is the outcome of a known underlying condition (IHRF, 2003).
Clinicians add to the confusion by routinely using the terms pseudotumor cerebri and benign intracranial hypertension interchangeably in both IIH and secondary intracranial hypertension.

Benign Intracranial Hypertension is essentially raised intracranial pressure with papilloedema (swelling of the optic discs, which is the point where the optic nerves enter the back of the eye).
There are said to be four diagnostic criteria: that is the CSF pressure is high; that the CSF composition is normal; that all the scanning investigations are normal; and that the signs and symptoms are solely of raised intracranial pressure (papilloedema and headache).
True Benign Intracranial Hypertension means that there is no underlying cause but the many other possible causes of similar conditions need to be excluded.

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.
