‘Hummingbird’ Sign in a Patient with Guam Parkinsonism-Dementia Complex [PDF]
Journal of Movement Disorders, 2017 We present a case of a 71-year-old male Chamorro patient from Guam who presented with progressive supranuclear palsy (PSP)-Richardson’s syndrome. Considering his strong family history of parkinsonism and a PSP phenotype, he was clinically diagnosed with ...

Hummingbird sign in progressive supranuclear palsy disease
Journal of Research in Medical Sciences, 2012 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".

Can the hummingbird sign contribute to the diagnosis of idiopathic normal pressure hydrocephalus? [PDF]
Turk J Med Sci, 2022 We read with great interest the article by Atalay et al. in which they illustrate the frequent presence of hummingbird signs in their patient group with idiopathic normal pressure hydrocephalus (iNPH) [1]. The results are substantially interesting; however, we believe that some points may be further deliberated for a better understanding of this ...

A newly described imaging finding for idiopathic normal pressure hydrocephalus: Can hummingbird sign contribute to the diagnosis? [PDF]
Turk J Med Sci, 2021 In this study, we aimed to evaluate whether morphological changes in the mesencephalon, which were previously described as a diagnostic tool for progressive supranuclear palsy, could be associated also with idiopathic normal pressure hydrocephalConsecutive 52 patients with a possible diagnosis of idiopathic normal pressure hydrocephalus (32 female ...

The Hummingbird sign: a diagnostic clue for Steele-Richardson-Olszweski syndrome. [PDF]
BMJ Case Rep, 2012 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 ...

"Hummingbird Sign" in Fragile X-Associated Tremor/Ataxia Syndrome. [PDF]
Mov Disord Clin Pract, 2015 A 64-year-old man progressively developed ataxic gait, 3-Hz high-amplitude, intentional/postural tremor, and dysarthric speech. FMR1 gene analysis revealed a premutation (89 CGG repeats) and a brain MRI showed mesencephalon atrophy with normal pons morphometry (the so-called “hummingbird” or “penguin” sign) along with middle cerebral peduncle ...
