[Brain perfusion study in patients with systemic lupus erythematosus and neuropsychiatric symptoms].

Neuropsychiatric manifestations in 25% to 70% of patients with systemic lupus erythematosus (SLE), generally in young people. The variability in its clinical expression and lack of diagnostic methods have hindered the diagnosis of Central Nervous System Lupus. When the literature was reviewed on this subject, an important variability was found between the Single Photon Emission Computed Tomography (SPECT) findings and the patient's clinical symptoms and disease course. The case we are presenting shows the usefulness of brain perfusion SPECT because it shows alterations in the central nervous system that are not detected with other imaging modalities.
