AB  - We report a patient with severe anorexia nervosa, treated with temporary total parenteral nutrition (TPN), in whom reversible hyperintensity of the anterior pituitary gland was seen on T1-weighted MR images. The anterior pituitary was isointense with white matter before TPN therapy and became markedly hyperintense after 3 months of treatment. The intensity normalized after TPN therapy was discontinued. The transient hyperintensity was also seen in the basal ganglia and dorsal brain stem. We believe the hyperintensity of the anterior pituitary may be attributed to the TPN therapy.
