Abstract
The objective of the study was to establish the diagnosis of kernicterus as a cause of seizures and abnormal movements in a 1-year-old child. We performed an MRI of the brain of the child on our 1.5 T scanner. The MRI of the patient showed high signals on T2-weighted images in the globus pallidus bilaterally, with no evidence of mass effect. Because of an increased risk of hearing loss, the brain-stem evoked response examination was also performed. The brain-stem evoked response examination showed bilateral severe sensorineural hearing loss. The presence of isolated hyperintense signals in basal ganglia (globus pallidi) was very useful in the evaluation of the structural changes in posticteric bilirubin encephalopathy.
