Teaching NeuroImages: "Penguin" or "hummingbird" sign and midbrain atrophy in progressive supranuclear palsy.
Jerome J. Graber, MD, MPH Robert Staudinger, MD, FAAN An 82-year-old man presented to us with a 2-year history of progressive difficulty walking. On examination, he had bradykinesia, bradyphrenia, axial rigidity without appendicular rigidity, cogwheeling, or tremor, and restriction of upward and downward gaze. Imaging revealed prominent midbrain atrophy without pontine atrophy, referred to as t...
متن کاملTeaching NeuroImages: diagnostic utility of FDG-PET in neurolymphomatosis.
A 70-year-old woman with a history of non-Hodgkin lymphoma presented with left-sided facial pain. MRI of the face, orbit, and neck was negative (figure). A week later, she developed hypesthesia in a V3 distribution. Repeat MRI was again nondiagnostic but fluorodeoxyglucose (FDG)-PET showed increased uptake along the left V3 branch of the trigeminal nerve, as well as in the parotid gland. Biopsy...
متن کاملFamilial progressive supranuclear palsy.
A progressive extrapyramidal syndrome and dementia occurred in three members of one family. The age of onset was in the seventh decade and the affected individuals showed many of the clinical features of progressive supranuclear palsy (PSP). Necropsy of one individual revealed the neuropathological features of PSP. We propose that this family has a familial form of PSP and review the evidence i...
متن کاملProgressive Supranuclear Palsy (PSP)
Introduction: Progressive supranuclear palsy (PSP) is a rare neurodegenerative disorder producing characteristic eye movement abnormalities in the classic presentation. The disease pathologically is marked by accumulation of abnormal tau proteins. There are useful MRI features, however the diagnosis remains clinical in the majority of cases, and no objective diagnostic test exists. Treatment at...
متن کاملProgressive supranuclear palsy.
This review concentrates on the molecular pathology of the protein tau, including its expression in various regions of the brain. The role of post-translational modifications in fibrillogenesis is also discussed, particularly hyperphosphorylation and glycation. However, the initiating event that causes aberrant tau processing remains unclear.
