How common is basilar invagination and brainstem bruising?

How common is basilar invagination and brainstem bruising?

Not common: Basilar invagination is not a common problem it can be seen most often in patients with rheumatoid arthritis or congenital anamolies of their cranial-cervical junction (where the skull meets the top of the spine). Brainstem compression can occur if the invagination is significant and/or longstanding. It should be evaluated by a skull base neurosurgeon. ...Read more

MRI brain find: presence of a persistent trigeminal artery and hypoplasia of the basilar artery? What is this I read its very rare & cause aneurysm?

MRI brain find: presence of a persistent trigeminal artery and hypoplasia of the basilar artery? What is this I read its very rare & cause aneurysm?

Dodged a bullet: Persistent Trigeminal art. is associated with aneurysm in 14%, likely on a congenital basis. If one does not exist, it is unlikely to develop. http://thejns.org/doi/abs/10.3171/jns.1971.35.5.0601 Association does not prove causality, but we don't understand the embryology well enough to know the causes of aneurysms. ...Read more

Is anger common after a stroke involving the frontal lobe of the brain? And can it be a permanet

Is anger common after a stroke involving the frontal lobe of the brain?  And can it be a permanet

Stroke and mood: Yes! Frontal lobe strokes can cause personality and/or mood changes. The FLs when healthy act as our "filter", keep us from losing control of our emotions, help us maintain attention, among other things. Damage to certain frontal areas can cause difficulty controlling anger, tendency to be 'black and white' in your thinking, or even depression. Yes these can be permanent, but also can be treated.. ...Read more

What are the symptoms of a middle back/spinal tumor? Is it rare?

What are the symptoms of a middle back/spinal tumor? Is it rare?

Yes, quite uncommon: But, what prompts your concerns? A variety of tumors may present over the thoracic vertebrae, some causing nocturnal pain responsive to aspirin, others compressing the spinal cord, resulting in urinary incontinence, leg weakness and numbness. Since often insidious, and slowly progressive, if there is high suspicion, would urge MRI study to pin down. ...Read more

Why is traumatic brain injury not a common cause of upper motor dysarthria?

Why is traumatic brain injury not a common cause of upper motor dysarthria?

TBI is a cause: TBI is a cause of upper motor dysarthria due to damage to the brain areas responsible for stimulating the nerves in the brain stem that trigger the muscles of speech and swallowing. ...Read more

Is a 4mm chiari, small cyst in the diploic in left parietal calvarium, and vascalar flow in the basal condylar veins something to be worried about?

Is a 4mm chiari, small cyst in the diploic in left parietal calvarium,  and vascalar flow in the basal condylar veins something to be worried about?

Probably not: 4mm of tonsilar herniation is not technically a chiari malformation as the cerebellar tonsils need to protrude more than 5mm to be abnormal. The other findings sound like normal variants found on an mri. If you are having symptoms you should see your doctor. ...Read more

In a chiari malformation, how problematic is having the vertebral artery compress the brainstem? If compressed by 15% ?

In a chiari malformation, how problematic is having the vertebral artery compress the brainstem? If compressed by 15% ?

Chiari malformation: A chiari malformation and a vertebral artery compression are two different issues. The key question would be if the 15% compression is causing symptoms related to the compression. With a 15% compression that would be unlikely but if symptomatic then i would encourage you to seek out a formal neurological workup. ...Read more

MRI brain find: presence of a persistent trigeminal artery and hypoplasia of the basilar artery? What chances my twin could have this too?

MRI brain find: presence of a persistent trigeminal artery and hypoplasia of the basilar artery? What chances my twin could have this too?

Depends on twin type: If you are in the denticle twin it is very possible your twin could have the same problem. If you are not and identical twin it is not likely. I would speak to your doctor who did the MRI about whether it would be wise for your identical twins do have a similar study. ...Read more

What is mild meningeal enhancement especially in the perisylvian regions? How serious and how long can it take to cure caused by japanese enceph.

What is mild meningeal enhancement especially in the perisylvian regions? How serious and how long can it take to cure caused by japanese enceph.

Brain imaging: Contrast material used on a ct or MRI of the brain may cause certain areas to look brighter, or enhanced, as compared to surrounding areas. Your findings may indicate inflammation of the lining of the brain near the sylvian fissure, which separates the frontal from temporal lobes of the brain. Japanese encephalitis can be deadly if not addressed quickly. Treatment is supportive, if you have je. ...Read more

What is the most common cause of brain aneurysms?

What is the most common cause of brain aneurysms?

Genetics: Defect in cerebral arterial walls which are often genetically determined, especially at branch points of the major brain arteries are the locations from which aneurysms arise. Hypertension and cigarette smoking are also big risk factors, especially hypertension. ...Read more

What is chronic lacune? Have chronic lacune is outer skull of 4mm. What could be its impact and how easy or difficult is it to cure?

What is chronic lacune? Have chronic lacune is outer skull of 4mm. What could be its impact and how easy or difficult is it to cure?

Lacunar stroke?: The term lacuna describes a small infarct or cavity in the brain that develops after resorption of necrotic tissue from an infarcted area a lacuna occurs from arterial insufficiency in the distribution of a penetrating branch of a large cerebral artery. This is not likely to either progress or regress, and if it has not created symptoms yet, will probably not. But risk of future stroke exists. ...Read more

What does this mean:  flow void is identified in major intracerebral blood vessels.  Small prominent perivascular spaces in inferior basal ganglia bil?

Doctorspeak: This is doctorspeak for normal findings on the MRI. A flow void indicates there is blood flow. Lack of a flow void would be bad. This is normal. Prominent perivascular spaces are likewise a benign (nothing to worry about) finding. ...Read more

What does it mean "Normal vascular flow voids are present in the distal carotid and vertebral arteries, the
basilar artery and the proximal anterior, ?

Normal arteries: Since the blood is moving during an MRI, the inside of the blood vessels appears to be a "flow void". This is the language used to report normal-appearing blood vessels. ...Read more

What are the symptoms of a neck tumor? Is it rare?

Palpable non tende3r: Several types of tumors noted in head and neck. Neither cause pain other than for presence of mass. Primary lesions are nodular and arise in the thyroid adjacent to wind pipe or in submax area due to lesions in submax salivary gland. Metastatic tumors are mostly nodal along the jugular vein arising from squamous lesions of oral cavity or thyroid. ...Read more

What is the comparison of glioma and capillary tangelictasia ? How can they be confused?

What is the comparison of glioma and capillary tangelictasia ? How can they be confused?

Tumor vs anomaly: Glioma is a brain tumor (neoplasm or new growth) of the supportive tissue (glia) cells while capillary angiectasia means dilated small blood vessels which can be harmful only if those vessels burst and bleed. Aggressive or high grade gliomas have many capillaries of their own and thus both lesions do have some something in common that shouldn't but may cause confusion ...Read more

Is swelling of brain tissues due to a brain tumor the same as raised intracranial pressure?

Is swelling of brain tissues due to a brain tumor the same as raised intracranial pressure?

Similar: Brain tumors can cause an increase in intracranial pressure but there are other things that can cause this. Increased intracranial pressure is just the pressure inside of the skull. This pressure can be increased by tumors but also by injury, bleeding, swelling and fluid blockages. ...Read more

My right anterior temporal lobe is atrophied (approx. 40 mm in size). How common is this for someone in their 40's and what issues could it cause.

Not common: As the age increases , cerebral atrophy is common .However , isolated temporal atrophy at the age of 40 is something that needs further evaluated . You might have neuropsychological test to see if there is any impairment in your memory , executive functions etc. ...Read more
