Abstract
Leber Hereditary Optic Neuropathy is an inherited optic neuropathy caused by mitochondrial DNA point mutations leading to sudden, painless loss of vision. We report a case of an 8-year-old boy presenting with a radiological phenotype of longitudinally extensive transverse myelitis on a background of severe visual impairment secondary to Leber Hereditary Optic Neuropathy (LHON). He was found to have dual mitochondrial DNA mutations at 14484 (MTND6 gene) and 4160 (MTND1 gene) in a family with a severe form of LHON characterised by not only an unusually high penetrance of optic neuropathy, but also severe extra-ocular neurological complications. The m.14484T>C mutation is a common LHON mutation, but the m.4160T>C mutation is to our knowledge not reported outside this family and appears to drive the neurological manifestations. To our knowledge there have been no previous reports of spinal cord lesions in children with LHON.

Abstract
We report the first case of definite neuromyelitis optica (NMO) with a pathogenic mitochondrial DNA (mtDNA) mutation for Leber's hereditary optic neuropathy (LHON) (G11778A point mutation). A 36-year-old Japanese woman had experienced recurrent neurological symptoms originating from involvements of the optic nerves and spinal cord. She finally lost her bilateral vision, and spastic paraparesis and sensory disturbances below the T6 level remained despite intensive immunotherapies. Brain and spinal magnetic resonance imaging (MRI) revealed T2-high-intensity lesions in the optic nerves and thoracic spinal cord, but no lesions in the brain. A blood examination revealed positivity for both anti-aquaproin-4 antibodies and an LHON mtDNA mutation.
