Idiopathic Intracranial Hypertension: Prognostic Factors and Multidisciplinary Management
Table 1
Diagnosis of idiopathic intracranial hypotension from Dandy’s criteria modified by Dandy et al. [1, 8].
Required for diagnosis of IIH
A
Papilledema
B
Normal neurologic examination except for cranial nerve abnormalities
C
Neuroimaging: normal brain parenchyma without evidence of hydrocephalus, mass, or structural lesion and no abnormal meningeal enhancement on MRI
D
Normal CSF composition
E
Elevated lumbar puncture opening pressure (>250 mm CSF in adults) in a properly performed lumbar puncture
Diagnosis of IIH without papilledema
In the absence of papilledema, a diagnosis of pseudotumor cerebri syndrome can be made if B–E above are satisfied, and in addition the patient has a unilateral or bilateral abducens nerve palsy
In the absence of papilledema or sixth nerve palsy, a diagnosis of pseudotumor cerebri syndrome can be suggested but not made if B–E above are satisfied, and in addition at least 3 of the following neuroimaging criteria are satisfied
1
Empty sella
2
Flattening of the posterior aspect of the globe
3
Distention of the perioptic subarachnoid space with or without a tortuous optic nerve
