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 moreSee 1 more doctor answer
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

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
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

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?
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 moreSee 1 more doctor answer
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.
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
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 moreSee 1 more doctor answer
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

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 moreSee 1 more doctor answer
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
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 moreSee 1 more doctor answer
