Is there evidence of cerebral arterial inflow hyperemia in idiopathic intracranial hypertension or not?

Dear Editor,

Whether or not there is evidence of an increase in the arterial inflow in patients with idiopathic intracranial hypertension (IIH) has remained controversial. In a recent paper, of the 42 children referred for possible IIH, 45 % had an arterial inflow which was greater than two standard deviations above the mean for the matched controls i. e. they were hyperemic [1]. Modelling of the venous outflow indicated that the increase in blood flow was high enough to induce IIH in these individuals [2]. In their most recent review paper published in the journal Fortschr Röntgenstr, Juhasz et.al. comment that the hypothesis of hyperemia in IIH could not be confirmed [3] and referred to one of their earlier articles as evidence corroborating this [4]. I wish to discuss some discrepancies I have noted in the author’s comparison paper.
