Review Case Reports
[A case of posterior reversible encephalopathy syndrome associated with Takayasu's arteritis].
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. ⋯ 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.

Review Case Reports
[A case of dural arteriovenous fistula at the craniocervical junction, which spinal MRI findings reveals increased intensity signal in Th3-medullary cone].
A 60-year-old woman had transient weakness of the legs and urinary retention for six weeks. She presented with a gait disorder and was admitted to the hospital. She showed symptoms of paraplegia, tingling in the lower extremities, dysuria. ⋯ Cervical and spinal angiography documented a dural arteriovenous fistula at the craniocervical junction that was fed by the right vertebral artery and the right ascending pharyngeal arteries and drained into the perimedullary veins. Surgical therapy improved her symptoms and MRI images. Craniocervical junction DAVF with thoracic-medullary cones lesion is rare.

Review Case Reports
[A case of rhabdomyolysis after status epilepticus without stroke-like episodes in mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes].
A 24-year-old man was referred to our hospital emergency department due to a sudden onset of convulsions after drinking. On arrival he presented status epilepticus and was managed by artificial ventilation. He had no brainstem signs or meningeal irritation. ⋯ We suspected a mitochondrial disease because of a significant increase in the lactate/pyruvate ratio (24.1) in the spinal fluid, and identified A3243G mutations in mitochondrial DNA (heteroplasmy 20%) in peripheral white blood cells. We diagnosed his illness as mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episodes (MELAS). This is a rare case presenting an acute onset of rhabdomyolysis following alcohol intake related to A3243G mitochondrial mutation without preceding stroke-like episodes.
