We evaluated findings in 14 patients with myotonic dystrophy (MD) using
magnetic resonance imaging of the brain and compared them with those in
age-matched controls with headache. There was an increased incidence of
ventriculomegaly and a lumpy and/or thick pattern of periventricular
hyperintensity in patients with MD as compared with the age-matched
controls. These white matter abnormalities do not appear to be
etiologically specific, but some possible explanations for these frequent
findings in MD are discussed.
