The long-term findings on brain magnetic resonance imaging (MRI) in a 7
10/12-year-old boy with a history of acute encephalopathy with bilateral
striatal necrosis following measles at the age of 22 months are
described. At the early stage of illness, brain MRI studies revealed
bilateral, symmetric basal ganglia lesions, predominant on the globi
pallidi, appearing as hyperintense signals on T-1- and T-2 weighted
images. Six years later, follow-up brain MRI studies showed that the
bilateral, symmetric lesions on the globi pallidi persisted with low
signal on T-1- and high signal on T-2 weighted images. At present, the
patient has some persistent neurologic signs. These findings suggest
that both clinical and neuroradiologic findings may persist in children
with acute encephalopathy with bilateral striatal necrosis following
measles
