In this section, we provide an overview of the MRI findings in three other subtypes of neurodegeneration with brain iron accumulation (NBIA): pantothenate kinase-2 associated neurodegeneration (PKAN, formerly known as Hallervorden-Spatz syndrome), aceruloplasminemia, and infantile neuroaxonal dystrophy (INAD) for the differential diagnosis of iron deposition in the basal ganglia. Here, PANK2 is linked to pantothenate kinase-associated neurodegeneration.
