Abstract
We report the case of a 26-year-old woman who was suffering from cerebral infarction concurrent with nephrotic syndrome caused by membranous nephropathy. MRI of the brain and angiography revealed cerebral infarction in the area of the right middle cerebral artery. The onset of her nephrotic syndrome was inferred to be contemporaneous with the cerebral infarction. Oral administration of prednisolone was effective for the nephrotic syndrome, and the patient was discharged from our hospital with mild hemiparesis at 2 months after the onset. In this case, we considered that vasculitis with collagen disease and intravascular dehydration associated with membranous nephropathy had caused the cerebral infarction.
