Figure 2.
T2 weighted brain magnetic resonance images of Patients 1 (A–B), 2 (C), and 3 (D). Images for Patient 1 were obtained at age 4 (A) and 7 (B) years, and the images for Patients 2 and 3 were obtained at age 4 years. Consistent with hypomyelination, there is poor differentiation between gray and white matter of all patients. Also, note the development of generalized atrophy and enlarged ventricles for Patient 1 between the ages of 4 (A) and 7 (B) years.
