Rudimentary meningocele, also known as spinal meningocele, is a medical condition characterized by the protrusion of the membrane covering the spinal cord and the spinal nerves through a defect in the vertebrae. This condition is often present at birth and can cause various complications if left untreated. Synonyms for rudimentary meningocele include myelomeningocele and spina bifida. Myelomeningocele refers to the severe form of meningocele where not only the protective membrane but also the spinal cord itself protrudes outside the body. Spina bifida, on the other hand, is a broader term referring to the incomplete closing of the backbone and membranes. Early diagnosis and appropriate medical intervention are crucial in managing this condition and minimizing its associated risks.
