Children are much more prone to exhibit these dysembryoplastic neuroepithelial tumours than adults. [1] The mean age of onset of seizures for children with DNTs is 8.1 years old. [1] Few other neurological deficits are associated with DNTs, so that earlier detection of the tumour before seizure symptoms are rare. [2]
Klüver–Bucy syndrome is a syndrome resulting from lesions of the medial temporal lobe, particularly Brodmann area 38, [1] causing compulsive eating, hypersexuality, a compulsive need to insert inappropriate objects in the mouth (hyperorality), visual agnosia, and docility.
CAA is associated with brain hemorrhages, particularly microhemorrhages.The accumulation of amyloid beta peptide deposits in the blood vessel walls results in damage of the blood vessels and hindrance of normal blood flow, making blood vessels more prone to bleeding [10] Since CAA can be caused by the same amyloid protein that is associated with Alzheimer's dementia, brain bleeds [11] are more ...
Unspecific cortical lesion on CT scan is confirmed cystic and benign with contrast-enhanced renal ultrasonography. Most renal cell carcinomas are now found incidentally. [19] Tumors less than 3 cm in diameter less frequently have aggressive histology. [20] A CT scan is the first choice
Redlich used the term 'miliary sclerosis' to describe plaques because he thought they resembled millet seeds, and he was the first to refer to the lesions as 'plaques'. [4] In the early 20th century, Oskar Fischer noted their similarity to actinomyces 'Drusen' (geode-like lesions), leading him to call the degenerative process 'drusige Nekrose ...
Signs and symptoms are not mutually exclusive, for example a subjective feeling of fever can be noted as sign by using a thermometer that registers a high reading. [7] Because many symptoms of cancer are gradual in onset and general in nature, cancer screening (also called cancer surveillance) is a key public health priority. This may include ...
[1] [2] These additional techniques are useful in determining what type of lesion the patient has, and allows physicians to determine more effective ways in treating the patient. (A) CT scan of a patient with middle cerebral artery stroke illustrating hypodensity areas within the temporal and frontal lobes.
Amygdala lesions change the functional pattern of activation to emotional stimuli in regions that are distant from the amygdala. [11] Other lesions to the visual cortex have different effects depending on the location of the damage. Lesions to V1, for example, can cause blindsight in different areas of the brain depending on the size of the ...
