title: Transient brain hyperperfusion detected with I-123 IMP SPECT in a patient with neuropsychiatric systemic lupus erythematosus.
abstract: We report the case of a 25-year-old woman with systemic lupus erythematosus. She complained of headache and left hemiparesis and was admitted to our hospital. She was in a coma after admission. Brain MRI showed no abnormalities, but brain single photon emission computed tomography showed diffuse hyperperfusion in the right frontal and temporal lobes. The calculated measured regional cerebral blood flow in the right hemisphere was increased to 40 to 55 mL/100 g/min, and that in the left was within the normal range of 25 to 35 mL/100 g/min. Two months later, the hyperperfusion was disappeared. The hyperperfusion could be explained by inflammatory changes.
