Abstract: Introduction: Intracranial idiopathic hypertension, also known as pseudotumor cerebri is a syndrome of increased intracranial pressure usually associated with sixth cranial nerve palsy as a false localizing sign, in the absence of structural pathology. The involvement of other cranial nerves is infrequent. Case report: A 20-year-old obese woman presented to our Institution with a subacute intracranial hypertension syndrome with involvement of multiple cranial nerves (III, IV, VI, VII), as well as cervical radicular symptoms. Multimodal evoked potentials showed prolonged latencies. Intracranial structural pathology was ruled out with imaging studies and a CSF tap test confirmed the diagnosis, since this procedure completely resolved the clinical manifestations of involvement of multiple cranial nerves, with improvement in the evoked potentials. Conclusion: Idiopathic intracranial hypertension may occasionally be associated with various cranial nerve palsies that impose challenges in the clinical practice. Apart from the sixth cranial nerve palsy, other false localizing signs can infrequently beingobserved, but the simultaneous involvement of multiple cranial nerves in pseudotumor cerebri is a condition rarely described in scientific literature.
