Intracranial extension of inflammatory pseudotumor of the orbit

Orbital pseudotumors are inflammatory lesions of the orbit of unknown etiology, which initially mimic an orbital neoplasm. Involvement of the other orbit is uncommon, and extension into the paranasal sinus rare. Intracranial extension of pseudotumor of the orbit is previously unreported. This is a case report of a patient with pseudotumor of the orbit with intracranial extension. The literature of the subject is reviewed.
