Résumé
Neurodegeneration with brain iron accumulation (NBIA), or Hallervorden- Spatz disease, is an extremely rare autosomal recessive disorder with cysteine-iron complex accumulation in globus pallidus, seen histopathologically. Magnetic resonance imaging offers an opportunity for diagnosis; however, therapeutic options are still ineffective. We report a case of 13-year-old girl, symptomatic since the age of three years with dystonia, poor scholastic performance and speech disturbances. She was admitted with aspiration pneumonia, and died before she could be investigated. Examination of brain at autopsy revealed iron deposition in bilateral globus pallidi, confirmed by special stains and elemental dispersion analysis by spectrometry and a diagnosis of Hallervorden- Spatz disease or NBIA was made. This report highlights the importance of autopsy and scanning electron microscopic examination in unsuspected cases where cause of death is not known.
