A T2-weighted image at the level of the MBs, acquired when the patient was 8 days of age, showing a hyperintense aspect of the MBs (A). A T1-weighted image (B) shows a hypointense MB signal. There is a bilateral hyperintense signal of the globus pallidus on a T1-weighted image (C), consistent with kernicterus. On follow-up after 7 months, there is atrophy with complete flattening of the MBs as seen on the sagittal T1-weighted image (D). An axial T2-weighted image shows persistent high signal of the globus pallidus bilaterally, with accompanying volume loss (E).
