Benign Neoplasm Of Cranial Nerves
The brain and spinal cord communicates with what is occurring in the internal organs and limbs by nerve fibers where are like electrical wires with insulation (myelin) and the "copper" (axon). Within brain and spinal cord these nerves connect to other nerves via synapses on both axons and dendrites. A nerve can carry information regarding sensations, and ...Read more
0%: All ependymoma brain tumors are technically malignant, meaning the cells are cancer and can grow into the surrounding brain tissue. However, most of these tumors (over 90%) are curable because the tumor is confined to one area, is slow-growing, and can be removed by surgery. Sometimes radiation alone is used for slow-growing brain ependymomas if surgery can't be performed. ...Read moreSee 1 more doctor answer
Multiple suggestive MR signs of pseudotumor cerebri, including partially empty sella along mild ectatic dilatation of the optic nerves' sheaths means?
Many: Brain tumors, benign or malignant, can have many different presentations. These include headache, seizures, focal neurological deficits such as speech problems, weakness in one limb or on one side, difficulty thinking properly etc. These symptoms are all non-specific, and can also be due to other brain disorders. ...Read more
S+s of end stage primary brain cancer, (aa iii) r medial temporal lobe, diffuse numerous cells. Growing!/brainstem and posterior temp./basal ganglia?
Ask for more info: Signs and symptoms can vary greatly with any 'end-stage' cancer. Things like if it has spread to other organs, impacting functional status and alertness (sleeping more, in bed most of the time), causing pain/seizures, and so on. His doctors can maybe determine what is most likely. If not involved already ask for hospice or palliative care help as they could also help answer what the s/s might be. ...Read moreSee 1 more doctor answer
Hard question: Any brain tumor can be malignant by position. Even if benign but in vital region is bad. A malignant metastasis may be easy to remove and cured by cure of the source. A primary malignant brain tumor may be easy to remove and cure or can be diffuse and impossible to remove or cure. ...Read moreSee 1 more doctor answer
Enlarged perivascular space in basal ganglia. Is by any cranial nerves? Double vision, enlarged pupils, trigeminal neuralgia, pulsating tinnitus
Metastasis : Secondary neoplasm refers to cancerous cells which have occurred at a different site (primary) and have moved (metastasized) to the secondary site (in this case brain and spine). These cells migrate by various means dependent on cancer type including via blood streamed, via lymphatics or by direct spread. The diagnosis of a secondary cancer is made by a specialist / pathologist by examining cells. ...Read more
What are the symptoms and signs of the upper motor neuron lesion (cortex, internal capsule, brainstem, spinal cord) ?
Cyst & tumor differ: A cyst is defined as an open space (sac) with an epithelial lining. This space may be filled with fluid, cellular debris, empty, etc. In general, a tumor is a solid growth, but may have cystic components. They can be composed of many different cell types. In this case, both are benign, but being on the optic nerve, they could still cause problems due to compression. ...Read more
Spinal Cord Tumor: Although spinal cord tumors are rarer than brain tumors, lesions of the spinal covering (meningiomas), spinal nerves (schwanomma or neurofibroma) or a metastatic tumor from breast or prostrate are the most common tumors to wrap around the spinal cord. Tumors of the spinal cord (ependymoma or astrocytoma) may look like its surrounding the cord, but are usually inside the tissue. ...Read moreSee 2 more doctor answers
Brain tumor: Tumors in the back part of the brain or posterior fossa can put downward pressure on the spinal cord and irritate the nerves in the neck. Muscle spasm can occur if there is erosion of the skull base and the occipital condyles. Blockage of cerebrospinal fluid as it flows from the brain to the spinal cord will cause neck pain. ...Read more
Can a small benign brain tumor on cerebellum cause nerves to be inflamed without causing raised intracranial pressure?
Uncommon: Brain Tumors affect over 10,000 people in the US each year, so they are not all that rare. The symptoms typically consisit of persistent Headaches which are new in onset and get progressively more severe over one or two months. Visual changes, sizures and loss of control of an arm or leg can also be the presenting symptoms. If there is strong suspicion it is easy to confirm with a CT or MRI scan ...Read more
If both benign and malignant tumours are formed by abnormal cell division, what makes malignant tumours cancerous and benign tumours non-cancerous?
Power to invade: Tumors are in fact caused by the accumulation of a series of genetic mutations. If something is going to be cancer, the mutations destabilize the genome and eventually mutations give the ability of the cells to invade and spread as they do early after conception. The idea that tumors are "cells dividing too rapidly" is fundamentally wrong and confusing -- it's the loss of controls. ...Read more
Meningiomas: A complex question as complications are related to location of the tumor, size of the tumor, and surgical accessibility - all of these queries should discussed with the surgeon considering the surgeon. ...Read more
"tumor" literally translates as "mass", so even a fresh bruise could be called a "tumor". Doctors use the term "neoplasm" (tranlates literally as new growth) to describe tumors that are abnormal growths of cells. These may be benign or malignant; "malignant" = cancer. In everyday usage, we use "tumor" ...Read more
A group of "new" growth cells that grow independently from normal tissue cells that are surrounding them. Benign neoplasms are typically slow growing, encapsulated and well differentiated. Benign neoplasms do not exhibit the classic signs that malignant neoplasms do, namely invasiveness, metastasis ...Read more
