The Smaller Left Cerebral Hemisphere Means What
What does this mean,there is a small old appearing cortical infarction in the superior anterior right cerebellar hemisphere superiorly?
Prior stroke: The films are indicative of older cerebral lack of blood flow causing a small stroke. Since this has occurred, there is risk of future stroke, and underlying cause should be sought. Consideration for medication to prevent further strokes very pertinent. Time to have full neurological evaluation. ...Read more
What does it mean when "minimal ectasia versus tiny aneurysm of the P1 segment of the left posterior cerebral artery?"
What is cerebral atrophy and T2 and FLAIR hyperintensities of the frontal white matter left greater than right mean?
" hypoplasia of the left anterior cerebral artery a1 segment is noted. Impression: normal mra of the circle of willis." what does above hypoplasia mea
Unusually small: That finding means that one of the arterial branches in your brain didn't develop fully. Not to worry though because if the report is'normal' that brain territory is getting blood from elsewhere. Many people have hypoplasia of a segmental artery which is usually inconsequential. ...Read more
Mechanisms: Usually, represents narrowing and closure of a large artery such as carotid or middle cerebral, but can be due to a clot circulating from a distant source, such as heart. A myocardial event might trigger a stroke in a susceptible older patient, and, in some cases, trauma can tear a blood vessel in neck (dissection). Causes include smoking, hypertension, diabetes, hyperlipemia, high homocysteine. ...Read more
Words: Pathogenesis is the origin or development of a disease. Ischemic stroke is damaged brain tissue due to loss of circulation (like from a clot)(as opposed to stroke from bleeding). Left cerebral hemisphere is the dominant area in most people and usually controls speech and right sided motor functions. ...Read more
Please advise what is the meaning of " lacunar infarct in left periventrikuler and brainstem infark"?
Please explain: small hypodensity within the peripheral aspect of the left cerebellar hemisphere?
God made us this way: There is virtual crossover for all aspects of our brain. Left to right and right to left. I cannot give you the reason, but that is the way it is. ...Read more
Small infarcts: Lacunar infarcts occur as a result of localized decreased blood flow resulting in localized cell death. This occurs in the more central penetrating vessels of the brain affecting the brains deep structures such as the putamen (part of the basal ganglia), thalamus, caudate pons and internal capsule. ...Read more
Opposite side: each side of the brain manages movement and sensation on the opposite side of the body, the left side of brain is involved in words, logic ,numbers, anaylysis, lists, linearity and sequencing. The right side is creative and involved with rythm, color, imagination, spatial awareness, color, daydreaming, holistic awareness and dimension. ...Read moreSee 1 more doctor answer
MRA revealed Small right and Rudimentery left posterior communicating arteries. What does this mean?
There: are various normal anatomic variations in this region, and small PCAs are a common one. It simply means that these arteries are underdeveloped...relatively small in caliber...compared to other arteries around the Circle of Willis region. ...Read more
My CT scan shows few ill defined linear reticular opacities noted in the superior segment of the left lower lobe. What does it mean?
Some differences: The dominant hemisphere usually determines the dominant hand, so, left hemisphere in right handers, but right hemisphere about only 40% left handedness. Pre-dominant speech connections over dominant side, especially left again. Yet delirium might occur from a stroke on the right side near temporal, parietal, occipital junctions. ...Read more
Anatomy: This means that on an MRI or CT scan, the cortex of the brain in the frontal area and parietal area is thinner than the average person. The vertex means near the top of the head/brain. If the person has neurologic symptoms that could be related to those areas of the brain, this could be the cause. It can also be an incidental finding. ...Read more
