H-magnetic resonance spectroscopy. diagnostic tool in recurrent headache in systemic lupus erythematosus. a case report

We describe serial MR-spectroscopy studies in a patient with systemic lupus erythematosus and headache. We used MR-spectroscopy to monitor disease activity during periods with and without headache. MR-spectroscopy investigates metabolic alterations and was used to explore the pathophysiological mechanism involved in the complications of systemic lupus erythematosus. Our patient underwent serial conventional MRI and MR-spectroscopy at times of controlled and uncontrolled headache, with or without visual aura. MR-spectroscopy showed an increase in the choline/creatine ratio in thalamus and posterior white matter only during periods of uncontrolled headache with visual aura. Conventional MRI scans were normal at all times. MR-spectroscopy should be used in the diagnosis and follow-up of headache in patients with systemic lupus erythematosus
