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).
If you have foraminal stenosis, knowing the definition of the condition can be helpful as you consider your treatment options. In general terms, âforaminal stenosisâ refers to the narrowing of the canals in the vertebrae that are responsible for protecting the nerve roots as they exit the spinal column. This constriction can disrupt regular nerve function and result in pain and other pain-related symptoms.
