"Eye of the Tiger" in a Non-Responsive Neuropsychiatric Patient: A Case Report

Hallervorden-Spatz syndrome is a rare neurodegenerative disorder with hereditary properties. It usually occurs in young adolescents with extrapyramidal symptoms besides disturbed mental function. In this study, we present a 23-year-old neuropsychiatric patient who primarily misdiagnosed to have conversion disorder. She had 5-year history of progressive dysarthria and generalized abnormal movements. After detecting the pathognomonic sign of "eye of the tiger" diagnosis was confirmed. The patient was discharged. She had satisfactory condition in her follow-up. Such a rare syndrome should be considered in patients with similar presentation, and upon the diagnosis, PKAN2 gene study should be done to detect possible new mutations.
