What is lumbosacral Myeloschisis?
Myeloschisis is the most serious and complex congenital anomaly in spina bifida manifesta (cystica). However, with improvements in medical care and increased understanding of its pathophysiology, the associated long-term morbidity and mortality rates have been significantly reduced.
Is Rachischisis the same as spina bifida?
These are two separate malformations that are often confused. Spina bifida refers to the failure of the closure of the dorsal aspect of the vertebral foramen of one or a few vertebrae. If many adjacent vertebrae are involved, it is called a rachischisis. These are failures of the vertebral arches to develop.
What is a dorsal Myeloschisis?
Abstract. Purpose: Limited dorsal myeloschisis (LDM) is a distinctive form of spinal dysraphism characterized by two constant features: a focal “closed” midline skin defect and a fibroneural stalk that links the skin lesion to the underlying cord.
What is sacral Dysraphism?
Spinal dysraphism (also called spina bifida) is a condition in which a baby’s spine and spinal cord do not form properly during pregnancy. The spine and spinal cords are then exposed to the surrounding environment inside or outside the body.
What causes myelomeningocele?
What causes myelomeningocele? The exact cause is unknown, but a lack of folic acid, exposure to viruses, exposure to radiation, and/or genetics are suspected. How is it diagnosed? It is diagnosed with prenatal blood work, amniocentesis, physical exam, and ultrasound.
What is Lipomyelocele?
A lipomyelocele is a type of lipoma that occurs with Spina Bifida. A lipoma is a fatty, fibrous tissue mass in the spinal column that extends on the backside through a Spina Bifida defect (gap or opening in the spine). It connects to the spinal cord against the skin.
What is Syringomyelocele?
[ sə-rĭng′gō-mī′ə-lə-sēl′ ] n. A form of spina bifida in which the fluid of the syrinx in the spinal cord is increased, expanding the cord tissue into a thin-walled sac that in turn expands through the vertebral defect.
What is posterior Rachischisis?
Rachischisis (Greek: “rhachis – ῥάχις” – spine, and “schisis – σχίσις” – split) is a developmental birth defect involving the neural tube. This anomaly occurs in utero, when the posterior neuropore of the neural tube fails to close by the 27th intrauterine day.
