Had a left posterior basal ganglia stroke.Was  in hospital r sided hemiparesis...Dr's did not explain poststerior ganglia?

Brain relay nuclei: The basal ganglia are a group of nerve relay centers (nuclei) in central part of the upper brain. They work with other areas of the brain in the control of limb and body movements, eye movements, thinking, and emotions. Just behind the lentiform nucleus of the basal ganglia is the posterior part of the "internal capsule." stroke in this area causes a hemiparesis on the opposite side of the body. ...Read more

Basal Ganglia (Definition)

This is the term for several areas of the brain that work together as a functional unit: the striatum (caudate and putamen), the globus pallidus, the substantia nigra, and the subthalamic nucleus. The most well known function of the basal ganglia is voluntary motor control, but it is also involved in development of routine behaviors; eye movements; and ...Read more

What does a small lacunar infarct in the right basal ganglia mean?

What does a small lacunar infarct in the right basal ganglia mean?

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

My mother, 84, MRI scan> subacute infarcts, bilateral frontal lobes, small vessel ischematic changes inthe basal ganglia, periventricular white matter?

Small vessel disease: Mri in a 84 years old lady showing infarcts and small vessel disease means she is having ministrokes. That is very common in that age group. If she has heart disease or carotid artery disease or risk factors like high BP or diabetes or high lipids they should be controlled and she should follow up with her dr who can give her further recommendations. ...Read more

S+s of end stage primary brain cancer, (aa iii) r medial temporal lobe, diffuse numerous cells. Growing!/brainstem and posterior temp./basal ganglia?

Ask for more info: Signs and symptoms can vary greatly with any 'end-stage' cancer. Things like if it has spread to other organs, impacting functional status and alertness (sleeping more, in bed most of the time), causing pain/seizures, and so on. His doctors can maybe determine what is most likely. If not involved already ask for hospice or palliative care help as they could also help answer what the s/s might be. ...Read more

Is an ischemic stroke in the basal ganglia always considered a lacunar stroke?

Matter of size: A lacunar stroke is due to a block in a smaller end artery, as contrasted to a carotid or middle cerebral artery obstruction, which would cause damage to a larger area of brain. Many strokes in the basal ganglia are small and often not noticed clinically, but the larger ones are very evident. ...Read more

Pet/ct scan of brain shown bilateral temporal(more severe on left side)parietal, thalami & basal ganglia hypo metabolism.What does it mean, pl advice.

Pet/ct scan of brain  shown bilateral temporal(more severe on left side)parietal, thalami & basal ganglia hypo metabolism.What does it mean, pl advice.

MaybeNothing: Pet/ct can show a region of hypometabolism, yes. But you describe many areas, including bilateral areas. That is much harder to accurately define on these kinds of tests, and results should be viewed with caution. Also, remember that the metabolism images should fit with what is wrong with the patient. ...Read more

Mri found bilaterally along the inferior lateral aspect of the basal ganglion, either old lacunar infarctions or bilateral benign cysts. Thoughts?

Mri found bilaterally along the inferior lateral aspect of the basal ganglion, either old lacunar infarctions or bilateral benign cysts. Thoughts?

Either unusual: The chance of lacunar infarcts in a 23 yo is pretty low. Similarly, having "bilateral cysts" seems somewhat unlikely, nor am i sure what kind of "cysts" the radiologist would be referring to. Review your MRI with your doctor. ...Read more

I had an MRI of the brain which showed a small old left basal ganglia lacunar infarction?

A risk factor: Regardless of the age of the prior stroke, you need to fully assess all relevant risk factors and start a protective anti-platelet med such as aggrenox, and perhaps lipitor (atorvastatin). Issue is not the prior lacunar infarct, but what may occur in future instead. ...Read more

What do you mean by: 1. Scalp hematoma, left parietal region 2, cerebral contusion left parietal lobe 3. Cerebral contusion left base cerebral hemisph?

What do you mean by: 1. Scalp hematoma, left parietal region 2, cerebral contusion left parietal lobe 3. Cerebral contusion left base cerebral hemisph?

Scalp hematoma: Scalp hematoma is a bleeding underneath the scalp in the upper left region of the skull. The contusion is in the same region and is a brusing and bleeding in the brain. #3. Is another bruising or bleeding on the left side of the brain but lower down towards the base of the skull. These injuries sound like there are a result of head trauma. ...Read more

Can you tell me what is tiny lacunar infarct of left basal ganglia?

Can you tell me what is tiny lacunar infarct of left basal ganglia?

Small Stroke.: Those findings are small strokes of specific areas of the brain that are subcortical or below the cortex. Two of the three mechanisms for those strokes are related to a chronic vascular disease associated with hypertension. Other likely risk factors include diabetes mellitus and possibly smoking. Symptoms will depend on what was affected. See your Neurologist or PCP. Not a 'classic stroke'. ...Read more

Can operate 14x6x6 lesion lying just inferior to the basal ganglia inferolateral to putamen, possible contiguity wth the claustrum anteroinferiorfly?

Can operate 14x6x6 lesion lying just inferior to the basal ganglia inferolateral to putamen, possible contiguity wth the claustrum anteroinferiorfly?

Is surgery needed?: That area is able to be reached surgically, but the real question is: does this lesion need surgery? Many findings on MRI do not require surgery. Sometimes, watching and waiting (with repeat mris) is the best course. Too many variables here to fully answer this question. Consultation with a neurosurgeon is warranted. ...Read more

What is inferior basal ischemia?

What is inferior basal ischemia?

Ischemia means : Decreased blood flow. I'm not sure if u are referring to the inferior basal part of the heart or the basal ganglia in the brain. Wherever it is, it suggests impaired blood flow and circulation related to high blood pressure, aging, diabetes, high cholesterol and smoking.Follow up with your dr. Take care! ...Read more

Result for my brain MRI -asymmetric decreased attenuation in the left basal ganglia, variant dilated perivascular spaces or punctate chronic lacune. ?

Result for my brain MRI -asymmetric decreased attenuation in the left basal ganglia, variant dilated perivascular spaces or punctate chronic lacune.  ?

MRI report: This is language used in radiology to describe what they see. Ordinarily, they cannot distinguish a small stroke (lacune) from a perivascular space. A "puntate lacune" though is very small. It is probably just the side view of a blood vessel (aka perivascular). Do you smoke? Do you have high blood pressure? Do you have diabetes mellitus? Atrial fibrillation? These are stroke risk factors. ...Read more

Brain right ventricle 8mm lesion -cyst or tumor?

Brain right ventricle 8mm lesion -cyst or tumor?

Hard to say: If the interpretation on the MRI by the radiologist is that it is a cyst, then it is likely benign. It also depends if there is any area of enhancement that would suggest a tumor. Also if you have serial MRI scans, you can tell if it is getting bigger or changing which is more likely a tumor. The location in the ventricle is important too. If it obstructs the foramen it could be a problem. ...Read more

What could an oval shaped low density lesion in the lower aspect of the right basal ganglia measuring 1cm be?

lesion in the brain: Any lesion in the brain, in this case a 1 cm lesion in the base of the right basal ganglia (near brainstem), is abnormal. There is no guessing about what it could be. I presume this was a ct or an MRI ordered by a primary care physician or neurologist. Whoever has this needs to have neurologic and possibly neurosurgical consultations. ...Read more

What is "old lacunar infarction at periventricular white matter of left temporal lobe" ?

Lacunes: Lacunes are small deep cerebral infarcts due to a primary arterial disease. They are usually located in the basal ganglia, internal capsule and pons usually in hypertensive patients. They are rare in the white matter of the cerebral hemispheres. See a neurologist if those findings belong to you. ...Read more
