But cysts can also be a marker for a problem called trisomy 18, which means an extra chromosome 18 in every cell of a baby's body.

Have hashimoto's; demyelinating brain lesions, one atypical; benign vertebral lesions, one atypical hemangioma. R these connected, or possible MS too?
Not connected: Hemangiomas and multiple sclerosis lesions can be difficult to differentiate on mri. Brain lesions of the demyelinating type are usually caused by multiple sclerosis but need to be diagnosed carefully, especially when atypical. Hemangiomas and multiple sclerosis are not connected. ...Read moreSee 1 more doctor answer
Are chiari 1 malformations ever acquired from a head injury or are they something people are born with? Is a 8mm chiari 1 malformation concerning?

0%: All ependymoma brain tumors are technically malignant, meaning the cells are cancer and can grow into the surrounding brain tissue. However, most of these tumors (over 90%) are curable because the tumor is confined to one area, is slow-growing, and can be removed by surgery. Sometimes radiation alone is used for slow-growing brain ependymomas if surgery can't be performed. ...Read moreSee 1 more doctor answer

A genetic accident: During formation of the egg or sperm can leave out an x chromosome in either one. A fetus whose genetic make-up includes the germ cell missing a chr. X has turner syndrome. One of 8 different genetic mutations is passed on to a fetus by 1 parent or happens spontaneously to cause noonan syndrome. 2 related genetic mutations are passed on to the fetus by 1 parent to cause klippel-feil syndrome. ...Read more
