Follow-up MR studies in Hallervorden-Spatz disease

Follow-up magnetic resonance (MR) studies of a child affected by Hallervorden-Spatz disease were performed over a period of 3 years. The hyperintense pallidi shown in the first examination changed to a mixed intensity target-like appearance. All the patterns observed in our patient have been described in the literature but in different subjects. Our data show these findings to be different manifestations of the same disease during its evolution.
