'Humming bird sign', 'Mickey Mouse sign', and 'morning glory sign' in progressive supranuclear palsy

Abstract

Progressive supranuclear palsy (PSP), also known as the Steele–Richardson–Olszewski syndrome, is a form of Parkinson-plus syndrome. Patients with PSP show interesting radiological signs such as the 'Humming bird sign' and the 'Mickey mouse sign'. Here, we report a patient with PSP, in whom the MRI brain demonstrated the 'Humming bird sign', the 'Mickey mouse sign', and the 'Morning glory sign'.
