title: Hypertrophic cranial pachymeningitis causing progressive unilateral blindness: MR findings.
abstract: A case of hypertrophic cranial pachymeningitis is described and the MR appearance presented. A gadopentetate-dimeglumine-enhanced MR scan enhanced markedly suggesting thickening and inflammation of dura and falx cerebri. The patient, a 72-year-old elderly man, had surprisingly little clinical abnormality. His only neurological manifestation was progressive unilateral blindness. The exact cause of his pachymeningitis was unknown, though neither rheumatoid arthritis nor other collagen disease was completely excluded.
