What does intramedullary tumor mean?
What does intramedullary tumor mean?
Intramedullary tumors are growths that develop in the supporting (glial) cells within the spinal cord. A spinal tumor is a growth that develops within your spinal canal or within the bones of your spine.
What is the difference between an extramedullary and intramedullary tumor?
Intramedullary intradural lesions are within the substance of the cord. Extramedullary lesions are located within the dural sac but exterior to the spinal cord.
What is the most common intradural extramedullary tumor in children?
The most frequently encountered intradural/extramedullary spinal tumors in the pediatric age group are metastases from primary intracranial tumors.
What is intradural intramedullary?
Intradural intramedullary lesions comprise 20 to 30% of all primary spinal cord tumors. 4. The remaining 70 to 80% of primary intradural tumors are intradural extramedullary tumors. 3. Intradural tumors are most likely to be found in the thoracic region, followed by the cervical and then lumbar spine.
What is dissociated sensory loss?
Dissociated sensory loss is a pattern of neurological damage caused by a lesion to a single tract in the spinal cord which involves preservation of fine touch and proprioception with selective loss of pain and temperature.
What is Lipomyelomeningocele?
A lipomyelomeningocele (pronounced lipo-my-elo-men-IN-go-seal) is a birth defect that affects a child’s backbone (spine). A lipomyelomeningocele is a fatty mass under the skin on the child’s back. It is usually in the middle of the back. The mass attaches to the spinal cord and may slowly pull on the cord.
What are the clinical signs of an intramedullary tumor of the spinal cord?
Pain and weakness are the most common presenting symptoms of intramedullary spinal cord tumors. Pain is often the earliest symptom, classically occurring at night when the patient is supine. The pain is typically local over the level of the tumor but may radiate.
Can spinal tumors heal?
Sometimes, patients may be cured by surgery alone if the entire tumor can be removed, but often this is not possible. Spinal cord ependymomas have the greatest chance of being cured with surgery, but treatment can cause side effects related to nerve damage.
How is a phyllodes tumor diagnosed on a needle biopsy?
If a phyllodes tumor is diagnosed on needle biopsy, it is most often treated by removing it completely (often with some type of breast-conserving surgery ). In some cases it might be difficult for a pathologist looking at a needle biopsy to tell for sure if the growth (tumor) is a fibroadenoma (a common benign tumor) or a phyllodes tumor.
Who is the doctor who makes the diagnosis after a biopsy?
After a biopsy, your health care team completes several steps before the pathologist makes a diagnosis. A pathologist is a doctor who specializes in interpreting laboratory tests and evaluating cells, tissues, and organs to diagnose disease.
How is a biopsy used to test for cancer?
doctors are not sure a lump is cancer, they may take out a small piece of it and have it tested for cancer and for infections or other problems that can cause growths that may look like cancer. The procedure that takes out a piece of the lump, or a sample for testing is called a biopsy. The tissue sample is called the biopsy specimen.
Can a Malignant phyllodes tumor spread beyond the breast?
Malignant phyllodes tumors can spread beyond the breast, although this happens less often than with more common types of breast cancer. If a phyllodes tumor is diagnosed on needle biopsy, it is most often treated by removing it completely (often with some type of breast-conserving surgery).
