Wilson disease is a rare genetic disorder that causes excessive copper accumulation in the body's tissues, especially the liver and brain. Symptoms typically appear between ages 6-20 and can include neurological or psychiatric issues as well as liver problems. MRI is crucial for evaluation and shows characteristic patterns of abnormal signals in the basal ganglia and brainstem. Regions often demonstrate hyperintensity on T2-weighted images and hypointensity on T1-weighted images. The accumulation of copper can also be detected by restricted diffusion on diffusion-weighted MRI sequences. Serial imaging may show progression of the distinctive "panda" and "cub" facial signs within the midbrain and pons over time.
