Abstract
Idiopathic intracranial hypertension (IIH) is a condition of raised
intracranial pressure (ICP) in the absence of space occupying
lesions. ICP is usually measured by lumbar puncture and a
cerebrospinal fluid (CSF) pressure above 250 mm H2O is one
of the diagnostic criteria of IIH. Recently, we have encountered
two patients who complained of headaches and exhibited disc
swelling without an increased ICP. We prescribed acetazolamide
and followed both patients frequently; because of the definite
disc swelling with IIH related symptoms. Symptoms and signs
resolved in both patients after they started taking acetazolamide.
It is generally known that an elevated ICP, as measured by
lumbar puncture, is the most important diagnostic sign of
IIH. However, these cases caution even when CSF pressure is
within the normal range, that suspicion should be raised when a
patient has papilledema with related symptoms, since untreated
papilledema may cause progressive and irreversible visual loss.
