Brain imaging findings in Liberfarb syndrome: hypomyelination and optic nerve and cerebellar atrophy.

Liberfarb syndrome is an extremely rare mitochondrial multisystem disorder, recently described and characterized by early-onset retinal degeneration and sensorineural hearing loss, spondyloepimetaphyseal dysplasia, joint laxity, short stature, microcephaly, developmental delay and intellectual disability, but clinical variability has been observed. We report a case that presented to the hospital with a flare-up of the disease. We describe the brain magnetic resonance imaging findings, which are still not well characterized, to raise awareness of this diagnosis.
