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).

Internal Medicine, 2016 A 79-year-old man presented with a slowly progressive gait disturbance. Brain MRI demonstrated ventriculomegaly and the hummingbird sign. A lumbar puncture showed no abnormalities of the cerebrospinal fluid. The improvement of the gait disturbance after the ventriculoperitoneal shunt led to a diagnosis of idiopathic normal pressure hydrocephalus ...
