“Ear of the Lynx" radiological sign in a patient with Primary Lateral Sclerosis.
The “Ear of the Lynx" radiological sign refers to fluid attenuated inversion recovery (FLAIR) sequence cone-shaped abnormalities at the forceps minor region of genu of corpus callosum, seen on magnetic resonance imaging (MRI) of the brain. This radiological sign has been reported in Hereditary Spastic Paraplegia (SPG) type 11 and SPG Type 15. In this case report, we discuss the first description of this radiological sign in a 59 year old female patient with PLS.
