Hallervorden-Spatz disease (HSD), a rare extrapyramidal motor illness, is usually only confirmed after death. In vivo diagnosis has relied hitherto on the combination of typical magnetic resonance imaging (MRI) findings (the "eye of the tiger" sign) and heterogeneous clinical symptoms of movement disorder which have been regarded as almost pathognomonic. We report on the diagnostic contribution of 123J-beta-CIT single photon emission computed tomography (SPECT) and 123J-IBZM SPECT in akinetic-rigid Parkinson's syndrome occurring in a case of HSD. In contrast to Parkinson's disease and multisystem atrophies, the results of both tests were normal. This constellation of findings shows that the degeneration lies primarily outside the nigrostriatal system, supporting arguments for the nosologic distinction of HSD from other extrapyramidal illnesses.

Purpose: The purpose of this review is to present current scientific reports on the pathophysiology, diagnosis and treatment of pantothenate kinase-associated neurodegeneration (PKAN).
Views: The condition is caused by a mutation in the PANK2 gene, which results in iron accumulation in the brain and changes in the functioning of biochemical pathways dependent on coenzyme A. There are two clinical types of PKAN, which differ in the time of onset of symptoms and speed of disease progression.

Pantothenate kinase-associated neurodegeneration (PKAN) is a rare autosomal recessive hereditary neurodegenerative disorder, usually caused by mutations in the pantothenate kinase 2 (PANK2) gene. We report a young female patient with atypical PKAN, harboring a novel heterozygous PANK2 mutation, diagnosed through clinical imaging and genetic analysis. The patient presented with dystonia and motor dysfunction after onset, but early brain MRI showed normal findings.

Clinical Vignette: A 23-year-old woman with pantothenate kinase-associated neurodegeneration (PKAN) presented with medication-refractory generalized dystonia and an associated gait impairment.
Clinical Dilemma: Bilateral globus pallidus internus (GPi) deep brain stimulation (DBS) can be an effective treatment for dystonia. However, outcomes for PKAN DBS have been variable and there are no standardized criteria for patient selection.
