Bilateral Spontaneous Lateral Intrasphenoidal and Transethmoidal Meningoceles: A Rare Presentation of Idiopathic Intracranial Hypertension

Idiopathic Intracranial Hypertension (IIH), also known as pseudotumor cerebri is a clinical syndrome of unknown etiology, which typically affects young, obese women of childbearing age and is characterized by increased intracranial pressure and bilateral papilledema. Unilateral and highly asymmetrical papilledema is a rare presentation in IIH occurring in less than 4% of patients with definite IIH and can poses a diagnostic challenge for the treating physician as it usually raises the suspicion of localized ocular pathology. As per current consensus, papilledema results in stasis of axoplasmic transport due to mechanical compression, leading to secondary vascular changes of venous dilation and hemorrhage. Given this mechanism, the underlying reasons for unilateral and asymmetrical papilledema remain unclear.

Symptoms And Signs

Idiopathic intracranial hypertension (IIH) is a syndrome of increased intracranial pressure without a mass lesion or ventriculomegaly and normal cerebrospinal fluid (CSF) composition. Patients typically present with a headache and visual symptoms and signs. Here, we discuss a rare presentation of spontaneous CSF leak secondary to IIH and mild ophthalmic finding that worsened after the cranial repair of the CSF leak.

Visual Disturbances

Fulminant idiopathic intracranial hypertension is a rare presentation of idiopathic intracranial hypertension in which visual decline occurs within 4 weeks of initial symptom presentation. Idiopathic intracranial hypertension usually presents with headaches, visual disturbances, and in women who are overweight. We present a case of idiopathic intracranial hypertension in which a female patient presented with rapid, severe vision loss within 8 days of symptom presentation and no other idiopathic intracranial hypertension symptoms. This case highlights a rare presentation of Fulminant idiopathic intracranial hypertension and the need for a quick diagnosis and treatment to preserve vision.
