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 ...

"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 ...

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 ...

Midbrain area and the hummingbird sign from brain MRI in progressive supranuclear palsy and idiopathic normal pressure hydrocephalus [PDF]
Journal of Neuroimaging, 2021 ABSTRACTBackground and PurposeThe main radiological finding in progressive supranuclear palsy (PSP) is reduced midbrain volume. Both qualitative (e.g., hummingbird sign) and quantitative (e.g., area measurements) markers have been noted. Recent studies have shown a similar reduction also in idiopathic normal pressure hydrocephalus (iNPH).
