Errors were introduced to the text of this article during production.

In the penultimate paragraph of the article, the first sentence contains the phrase ‘under 60 years of age’. This is incorrect and should read ‘over 60 years of age’. The corrected sentence should read ‘Intramedullary spinal cord astrocytomata are rare and seldom affect those over 60 years of age.’
