What is difference in lipomeningocele and lipomyelomeningocele?

Answer 1

Bellow some definitions from the medical dictionary of US National Library of Medicine. 1. Main Entry: me·nin·go·cele Variant(s): also me·nin·go·coele \me-ˈniŋ-gə-ˌsēl, mə-ˈnin-jə-\ Function: noun : a protrusion of meninges through a defect in the skull or spinal column (as in spina bifida) forming a cyst filled with cerebrospinal fluid 2. Main Entry: my·e·lo·me·nin·go·cele Pronunciation: \ˌmī-ə-lō-mə-ˈniŋ-gə-ˌsēl, -mə-ˈnin-jə-\ Function: noun : spina bifida in which neural tissue of the spinal cord and the investing meninges protrude from the spinal column forming a sac under the skin 3. Main Entry: my·e·lo·cele Pronunciation: \ˈmī-ə-lə-ˌsēl\ Function: noun : spina bifida in which the neural tissue of the spinal cord is exposed source:

Lipomeningocele

Lipomeningoceles are a form of occult spinal dysraphism in which there is intact skin covering the defect (298,419). The spinal cord remains within the spinal canal, with the junction between the spinal cord and the lipoma also residing within the canal. (Figure 63.12) In general, individuals with lipomeningoceles are normal at birth. Neurologic findings are first noted during the second year of life, with most patients exhibiting some neurologic deficits by early childhood. The most common presentation is a subcutaneous fat collection in the lower back and upper buttocks. Approximately 50 percent of affected individuals have cutaneous markings, such as a hairy patch, a midline dimple, or a hemangiomatous nevus. The primary goal of surgery is to untether the spinal cord. Removal of the entire lipoma is usually not performed, because the neural tissue extends into the lipoma and aggressive surgical excision of the lipoma, may cause significantly more neurologic damage.
