Brain MRI (at 5, 16, and 35 months) of a patient with Sjögren-Larsson syndrome

T2-weighted MR images (3100/98 [TR/TE]). There is a delay in the maturation of the white matter on all three images.

(A) At five months of age, the unmyelinated periventricular white matter shows no abnormal signal intensities.

(B and C) Images obtained at 16 (B) and 35 (C) months of age show nonprogressive, slight signal-intensity abnormalities in the periventricular white matter that mainly involve the occipital trigones.

MRI: magnetic resonance imaging.
