Symptoms of brain injuries can also be influenced by the location of the injury and as a result impairments are specific to the part of the brain affected. Lesion size is correlated with severity, recovery, and comprehension. [4] Brain injuries often create impairment or disability that can vary greatly in severity.
Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.
In fact, when herniation is visible on a CT scan, the prognosis for a meaningful recovery of neurological function is poor. [2] The patient may become paralyzed on the same side as the lesion causing the pressure, or damage to parts of the brain caused by herniation may cause paralysis on the side opposite the lesion.

Frontal lobe disorder, also frontal lobe syndrome, is an impairment of the frontal lobe of the brain due to disease or frontal lobe injury. [5] The frontal lobe plays a key role in executive functions such as motivation, planning, social behaviour, and speech production.
All types of brain tumors may produce symptoms that vary depending on the size of the tumor and the part of the brain that is involved. [2] Where symptoms exist, they may include headaches, seizures, problems with vision, vomiting and mental changes. [1] [2] [7] Other symptoms may include difficulty walking, speaking, with sensations, or ...
The tumefactive lesion may mimic a malignant glioma or cerebral abscess causing complications during the diagnosis of tumefactive MS. T2-hypointense rim and incomplete ring enhancement of the lesions on post-gadolinium T1- weighted imaging on brain MRI enable accurate diagnosis of TDL [3]
Brain biopsy. HPS stain. The current standard for diagnosis typically includes positive CSF cytology, vitreous biopsy, or brain/leptomeningeal biopsy. [10] Histopathological confirmation is essential for definitive diagnosis. [11] MRI or contrast enhanced CT classically shows multiple ring-enhancing lesions in the deep white matter.
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
