Excerpt

Swallow tail sign (STS), which represents nigrosome-1 in the substantia nigra on susceptibility-weighted imaging (SWI), has been recognized as a promising magnetic resonance imaging (MRI) biomarker for Parkinson’s disease (PD) [1]. Here, we report a neurosyphilis patient with STS loss on SWI, who was misdiagnosed as Alzheimer’s disease. …
