HÃ¼rthle cell cancer has the highest incidence of metastasis among the differentiated thyroid cancers. Metastatic disease is reported at the time of initial diagnosis in 10-20% of patients and in 34% of the patients overall.
By Michael Perry, M.D. Foraminal narrowing, or foraminal stenosis, is a condition of the spine that can cause pain and other symptoms resulting from spinal nerve root compression. At every level of the spine, a pair of nerve roots runs through the spinal column via small openings called foramina (singular: foramen).
A foramen exists at each level of the spine with one on each side. At each level, a spinal nerve, a nerve coming to or from the spinal cord, passes through the foramen. Because the foramen is a relatively small area, anything impinging on that area can cause foraminal stenosis is pinch the nerves inside the foramen.While foraminal stenosis generally occurs in the setting of other degenerative disease of the spine, it can present as the primary problem in some patients.ecause the foramen is a relatively small area, anything impinging on that area can cause foraminal stenosis is pinch the nerves inside the foramen.
