Cerebral hemisphere

What is Cerebral hemisphere?

The large mass of the telencephalon, on either side of the midline, consisting of the cerebral cortex and its associated fiber systems, together with the deeper-lying subcortical telencephalic nuclei (basal nuclei [ganglia]).

Questions and answers on "Cerebral hemisphere"

My 15 month old daughter recently received the following results from a brain MRI. Could you help us interpret?
Mild degree of the volume loss of both the gray and white matter in the supratentorial cerebral hemispheres with prominent overlying subarachnoid spaces and secondary dilatation of the frontal horns left more than right.
Explanation could be delayed motility of the ventricular system.

Welcome to Health care magic.

1. Mild degree of volume loss / atrophic changes - seen in case of dismyelination disorders or any systemic causes.
2.The subarachnoid spaces seen prominent ( its seen in volume loss cases)
3.Ventricles / frontal horns seen dilated - seen when there is distal...

Sir, My Father is 73 Years Old and is suffering from Parkinson's. Some times he is finds his limbs to be stiff. His CT Scan Brain says nodular calcified granuloma in right posterior parietal cortex, No Perilesional oedema and Age related atrophic changes in the bilateral cerebral hemispheres. what does it mean.

doctor1 MD

hi..the CT scan report u mentioned says that bilateral cerebral hemispheres has agebrelated atrophy it means that in brain there are two hemispere as age progress the volume of these hemispere decrese its a normal entity seen in old age group popleand nxt calcified granuloma with nonperilesional...

Non-specific T2 and FLAIR hyperintensities in bilateral frontal subcortial white matter, rest of the cerebral hemispheres show normal morphology with normal parenchymal signal intensity seen in my recently done MRI. I am using Tegretal CR 200 for 3 years. Is the report good or bad?

doctor1 MD

Hello
Thanks for writing to HCM

Findings are non significant.It is not related to tegretal.
FLAIR or T2 weighted hyper intensities less than five in number in deep white matter of brain can be ignored.
Mostly it is due to ischemic changes(decreased blood supply) that involves small blood...

My child is one year old., and he had a IVF Grade 3 and a premature baby. We have done MRI Brain yesterday, and the findings are ......
1. Paucity of the white matter noted in both cerebral hemispheres
2. Mild to moderate dilation of the 3rd and both lateral ventricles noted.
3. Irregular gliosis in left fronto-pariental periventricular region......

Can I have a sense of what all these will result in ??

doctor1 MD

Hello,
Wellcome to HCM
The child is showing features of developmental abnormality and there are good amount of chances that the child will be lagging in development.
These features are common in IVP born children especially when they are premature.
It is less likely that the baby will catch up...

My brain scan says this:
There is patchy abnormal signal within the deep and subcortical white matter of both cerebral hemispheres especially within both frontal lobes in the anterior watershed distribution. The appearances are in keeping with chronic small vessel disease. the abnormal white matter lesions do not have the morphology of inflammatory lesions. Mild generalised cerebral and cerebellar volume loss with sulcal prominence at the vertex of both cerebral hemispheres.

What does this mean please.

doctor1 MD

Hi,

Thank you for posting your query.

I have noted your MRI brain findings. First of all, I would like to reassure you that these findings do not represent any serious brain disease.

I need to know your age and clinical symptoms to explain you the significance of your MRI findings.

Chronic small...

Hi I have got results from my recent mri scan they show high signal foci in white matter of both hemispheres involving the frontal lobes overall they lie in a peripheral distribution there is also high signal focus lying within the right lateral aspect of the corpus callosum adjacent to the body of lateral ventrical

doctor1 MD

Hi,

Thank you for posting your query.

I have noted your MRI brain findings.

The interpretation of MRI findings depend on the age and patient's symptoms. So, I request you to get back with your age and current symptoms.

It is also important to see all the pictures.

Based on the information...

My father-in-law gone thru CT Scan of his brain as he got fainted two times. Findings: There are patchy hypodensities in left frontal paraventricular white matter. Remaining brain parenchyma of both cerebral hemispheres show no significant abnormality. Sylvian fissures, cortical sulci, both lateral & third ventricles are mildly dilated. interventricular septum is in the middle. Rest other findings are normal.So what should we interpret? Is it a serious matter? How it can be cured?

doctor1 MD

Hello

Patchy hypodensities in periventricular white matter in frontal lobe may be due to many reasons like infarct,gliosis etc.

So,your father-in-law need monitoring of conditions that leads to ischemic changes like hypertension,altered lipid profile,diabetes mellitus so that further progression...

My grandson was born 9 weeks premature but doing all the right things .An ultra sound has found one side of hes brain is bigger than the other.He is now 2 weeks old.What does this mean?

doctor1 MD

Hello,

Thanks for posting your query.

On an ultrasound the finding of one half of brain bigger than the other might just be a slight normal variation. Anatomically slight variation is present in sizes of two cerebral hemispheres.

If one half of brain is abnormally large then it might be...

today my mother did a MRI and then her brain tumor has detected.i dont understand the report therefore i am writing that is witten in the report..."Extraaxial lobulated strongly enhanching T1 iso T2 slightly hyperintense mass measuring about 2.6 cm AP* 2.6 cmRL * 2.0 cm CC is seen in supracellar region elevation the optic chiasma.
on T2WI and FLAIR images hyperintense foci are noted in sub-cortical & deep white matter of both cerebral hemispheres,suggesting microvascular chronic ischemic changes in these location.

doctor1 MD

Hello
Thanks for writing to HCM
MRI report suggests that there is extra axial (outside the axial region of brain) rounded mass measuring about 2.6 cm AP* 2.6 cmRL * 2.0 cm CC lesion in suprasellar region of brain which enhanced strongly on contrast administration and lesion is causing elevation...

Recent questions on  Cerebral hemisphere

doctor1 MD

Hi,

I would like to know the meaning of the following:

MR Scan of brain reveals normal grey-white matter differentiation of both cerebral hemisphere. There are patchy white matter hyperintense foci on T2 weighted sequence in the perpendicular & subcortal white matter of both cerebral hemispheres. These lesion are iso-to hypointense on T1 & bright on FLAIR sequence. None of these lesions are bright on diffusion sequence. These features are consistent with chronic white matter ischaemic changes due to small vessel arteriosclerotic changes. No mass effect / midline shift seen. bilateral basal ganglia are normal.

Apart from this cerebellar hemispheres & brainstem, internal auditory canal & its content, ventricular system, sellar and parasellar regions, and calvarium are mentioned as normal.

I would appreciate the meaning of this. Please reply in English.

Thanks,
Greg

doctor1 MD

Brain scan report states: There are a few patchy hypo densities in the white matter of the cerebral hemispheres which are non specific. Also: minimal white matter changes that likely represent early or minimal ischemic changes. What does all this mean?

last week my mother had gone though the MRI brain and the report says:- Discrete and confluent T2 hyperintense foci are seen in bilateral cerebral, suggesting ischaemic changes.. [2] Isolated tiny FLAIR hyperintensity is seen in the right cerebellar hemisphere [3] Age related ventricular and cerebral sulcal prominence is seen. I would like to request if you can guide us. As she was suffering from buzzing sound in her left ear so the dr suggested for audeoment test and MRI brain, the report which I receive i have mentioned that in the above. waiting for your advise.
