Detailed Instructions: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Q: Abstract: We report the first antemortem diagnosis of a lesion showing Balo's concentric sclerosis. A patient with a progressive left hemiparesis had a ring-enhancing, low-density right frontal white matter lesion. On myelin stains of a needle biopsy, alternating demyelinated and myelinated zones in the white matter were diagnostic of concentric sclerosis. The patient improved with prednisone therapy, but relapsed temporarily 15 months later. CT and MRI showed additional lesions, but no features unique to this process. He remains alive and employed 3 years after diagnosis.
Which is the apt title for the abstract? option1: Balo's concentric demyelination diagnosed premortem. option2: Iatrogenic hand injuries in outpatients.
A:
Balo's concentric demyelination diagnosed premortem.
