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).
The word foramen means opening. The foramen in the spine is a small opening in between vertebrae where the spinal nerves leave the central spinal canal and move out into your arms or legs. This foramen or opening can often become narrowed and pinch the nerves. The word stenosis means narrowed.
