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. The gene discussed is PANK2; the disease is neurodegeneration with brain iron accumulation 2A.
