Hypotension intracrânienne : une cause rare de céphalées au cours du lupus systémique

Abstract

IntroductionSpontaneous intracranial hypotension (SIH), a rare cause of headache, may be idiopathic or secondary, in particular to Systemic Lupus Erythematosus (SLE) where it remains exceptionally evoked or documented. Case reportA 36-year-old woman presented with postural headache, recurrent nausea and vomiting. The discovery of a nephrotic syndrome led to the diagnosis of SLE with lupus nephropathy (class IV-G-(A)). A brain MRI showed signs of intracranial hypotension with tonsil ptosis and a left parietal hypersignal, and leading to a diagnosis of neurolupus with SIH. Treatment with prednisone, cyclophosphamide, and then mycophenolate mofetil allowed a rapid complete response of all systemic, renal and neurological manifestations, including the iconographic signs of intracranial hypotension. ConclusionHeadaches are frequent and often unexplained during SLE. Their orthostatic character should, if appropriate, suggests a SIH and lead to perform a brain MRI, even in the absence of other neurological signs.
