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).
1 At each level in the spine where there is a disc, right and left nerve roots come out to innervate tissues in the body. 2  The holes that they come out are called neural foramina. 3  This statement means that the size, or diameter, of those holes has been minimally narrowed by this diffuse disc bulge.
