Gradual cranial migration of the neurological deficits (problems relating to the nervous system), is known as ascending syndrome and is said to be a typical feature of diffuse myelomalacia. Although clinical signs of myelomalacia are observed within the onset (start) of paraplegia, sometimes they may become evident only in the post-operative ...
Spinal nerve sheath tumors generally arise as single lesions. [1] Presence of multiple lesions is associated with genetic conditions including neurofibromatosis type 1, neurofibromatosis type 2, and Schwannomatosis. [1] [3] [4] Most spinal schwannomas are intradural-extramedullary, growing inside the thecal sac, but outside the spinal cord ...
Spinal cord compression is commonly found in patients with metastatic malignancy. [10] Back pain is a primary symptom of spinal cord compression in patients with known malignancy. [11] Back pain may prompt a bone scan to confirm or exclude spinal metastasis. Rapid identification and intervention of metastatic spinal cord compression is ...
Neuro-oncology is the study of brain and spinal cord neoplasms, many of which are (at least eventually) very dangerous and life-threatening (astrocytoma, glioma, glioblastoma multiforme, ependymoma, pontine glioma, and brain stem tumors are among the many examples of these).
Historically, vascular anomalies have been labeled with descriptive terms, according to the food they resembled (port wine, strawberry, cherry, salmon patch). This imprecise terminology has caused diagnostic confusion, blocked communication and even caused incorrect treatment, as it does not differentiate between various vascular anomalies. [4]
Vascular myelopathy (vascular disease of the spinal cord) refers to an abnormality of the spinal cord in regard to its blood supply. [1] The blood supply is complicated and supplied by two major vessel groups: the posterior spinal arteries and the anterior spinal arteries —of which the Artery of Adamkiewicz is the largest. [ 2 ]
Perivascular epithelioid cell tumour, also known as PEComa or PEC tumour, is a family of mesenchymal tumours consisting of perivascular epithelioid cells (PECs). [1] These are rare tumours that can occur in any part of the human body. The cell type from which these tumours originate remains unknown.
Usually, gliomas begin in the glial cells that surround the nerve cells to help them function. Many gliomas exhibit cells that do not exist in normal brain tissue and are not seen in glial differentiation. [1] Of these gliomas are astrocytomas, which is a type of cancer that occurs in the brain or spinal cord.
