Hummingbird sign in progressive supranuclear palsy disease
نویسنده
چکیده
Progressive supranuclear palsy (PSP) is characterized by slowness, rigidity, bradykinesia, repeated falls, downgaze limitation and dementia. Midbrain atrophy on magnetic resonance imaging is highly suggestive of PSP and is described as "hummingbird sign". This sign is very helpful in differentiating PSP patients from those with Parkinson's disease.We hereby report a 72-year-old female case of PSP primarily diagnosed with Parkinson's disease.

DESCRIPTION Progressive supranuclear palsy (PSP), previously known as Steele-Richardson-Olszweski syndrome, is an atypical parkinsonian syndrome with a prevalence of ∼5/100 000. It is an important differential diagnosis of more common idiopathic Parkinson’s disease (iPD), where clinical differentiation is not straightforward and characteristic neuroimaging often yields a diagnostic clue. We des...

– Diagnosis in neuroimaging involves the recognition of specific patterns indicative of particular diseases. Pareidolia, the misperception of vague or obscure stimuli being perceived as something clear and distinct, is somewhat beneficial for the physician in the pursuit of diagnostic strategies. Animals may be pareidolically recognized in neuroimages according to the presence of specific disea...
