Contiguous and symmetrical disease expansion and massive necrosis of the cerebral white matter in a patient with neuromyelitis optica

Abstract

The present report discusses the case of a woman with neuromyelitis optica (NMO) who exhibited bilateral optic neuritis, longitudinally extensive myelitis, serum anti-aquaporin-4 antibodies, and a unique pattern of white matter involvement. The disease duration was 26 years, and the patient died at the age of 65 years. Sequential magnetic resonance images obtained during the last 6 years of life revealed leukoencephalopathy-like lesions extending symmetrically and contiguously from the periventricular regions, which had begun to transform into multiple cavities with semi-annular partitions. This unique pattern of white matter abnormalities should thus be considered among those associated with NMO.
