title: [A case of posterior reversible encephalopathy syndrome associated with Takayasu's arteritis].
abstract: A 75-year-old woman presented with a 4-month history of repetitive loss of consciousness, dizziness, and ear fullness. Fluid attenuation inversion recovery magnetic resonance imaging showed high-intensity areas in the right occipital lobe, both frontal lobes, and parietal lobes, and the patient was therefore admitted to our department for further examination. Neurologic findings included a positive Barré sign (right upper extremity), impaired tandem gait, and positive left-sided Babinski reflex. The patient was diagnosed with Takayasu's arteritis owing to a difference in blood pressure between the left and right upper extremity, weakened pulse in the left upper extremity, as well as thickened arterial wall, and delayed enhancement on a contrast-enhanced computed tomography image. The head magnetic resonance imaging findings disappeared within 4 months and the patient was diagnosed with posterior reversible encephalopathy syndrome. Posterior reversible encephalopathy syndrome associated with elderly female Takayasu's arteritis is rare. ; the present case therefore offers valuable information.
