T2*-weighted images (TR 400 msec/ TE 25 msec) obtained with a gradient echo sequence in the same patient at 42 years old. (a) A cross-section at the pontine level. The signal loss with central hyperintense lesions in the dentate nucleus is more obvious than that observed on T2WI. (b) An image of the midbrain demonstrates the hypointense change in the red nucleus. (c) Cystic degeneration of the basal ganglia with a rim of peripheral signal loss is obvious. In the thalamus, bilateral hyperintense abnormalities surrounded by slight hypointensity can be seen. (d) An image of a section of the central part of the lateral ventricles. (e) The iron deposition in the cerebral cortex is detected as signal loss.
