Thalamic gliomas are most often discovered on magnetic resonance imaging following symptoms, with the most common presenting symptom being motor deficit. [2] While a definitive diagnosis of the neoplasm cannot be made without a biopsy of the tumor, biopsies have historically been avoided due to the extreme sensitivity of the region.
Diffuse midline glioma, H3 K27-altered (DMG) is a fatal tumour that arises in midline structures of the brain, most commonly the brainstem, thalamus and spinal cord.When located in the pons it is also known as diffuse intrinsic pontine glioma (DIPG).

A glioma is a type of primary tumor that starts in the glial cells of the brain or spinal cord.They are cancerous but some are extremely slow to develop. [2] [3] Gliomas comprise about 30 percent of all brain tumors and central nervous system tumours, and 80 percent of all malignant brain tumours.
It is usually caused by a brain tumor such as a low-grade glioma or astrocytoma located in the hypothalamic-optic chiasmatic region. [1] It is not yet understood how diencephalic syndrome causes the effects on appetite and metabolism which are seen, though inappropriately high growth hormone release has been proposed, [ 4 ] as has excessive β ...
In males, researchers suggest that the overall reduction in cancer death rates is due in large part to a reduction in tobacco use over the last half century, estimating that the reduction in lung cancer caused by tobacco smoking accounts for about 40% of the overall reduction in cancer death rates in men and is responsible for preventing at least 146,000 lung cancer deaths in men during the ...
It is called tumefactive as the lesions are "tumor-like" and they mimic tumors clinically, radiologically and sometimes pathologically. [1] These atypical lesion characteristics include a large intracranial lesion of size greater than 2.0 cm with a mass effect, edema and an open ring enhancement. A mass effect is the effect of a mass on its ...
Terminal illness or end-stage disease is a disease that cannot be cured or adequately treated and is expected to result in the death of the patient. This term is more commonly used for progressive diseases such as cancer, rather than fatal injury.
