Spinal Dysraphism Myelomeningocele eMedicine Radiology

Description: Spinal dysraphism can be classified as closed forms or open forms, which include myelocele, meningocele, and myelomeningocele. These open forms are often associated with hydrocephalus and Arnold-Chiari malformation type II and may be classified as spina bifida aperta. Von Recklinghausen (1886) gave a detailed account of spina bifida cystica (aperta). Spina bifida is described in the medieval literature, although the condition was recognized even earlier.
