A 37-year-old woman presented with a previous history of learning disability, started when she was 23 years old, with progressive spastic gait, cerebellar signs, cognitive decline, and peripheral neuropathy. Parents, who consented with this publication, were non-consanguineous and the patient had two other affected siblings. Brain MRI disclosed an ultrathin corpus callosum and periventricular white matter abnormalities along with the characterization of the “ear of the lynx” sign [Figure 1]. Molecular analysis of SPG11 revealed a splicing pathogenic variation c.2444 + 1G > C (NM_025137.3), consistent with the diagnosis of spastic paraplegia 11 (SPG11). SPG11 is the most frequent presentation of autosomal recessive hereditary spastic paraplegia (HSP) and has characteristic MRI findings., In investigation HSP, brain MRI is usually more helpful than spinal cord MRI.
