How do you approach new-onset idiopathic intracranial hypertension (IIH) with someone who has history of systemic lupus erythematosus?

Would you consider this to be neuropsychiatric SLE (NPSLE) manifesting as IIH? How do you approach someone with a history of SLE that has been well controlled for decades on CellCept and Plaquenil, who develops dizziness with a workup concerning for idiopathic intracranial hypertension (IIH), severe transverse sinus stenosis on MRV, empty sella, and elevated opening pressure? APS labs are positive, but otherwise, lupus markers are normal. What is your approach to treatment? Pulse steroids/escalate to Rituxan/Cytoxan, or treat this as you would an isolated IIH and consider SLE incidental?
