Cranial lesions can be caused by a variety of factors, including trauma, infections, tumors, or vascular issues such as strokes. Infections like meningitis or encephalitis can lead to inflammation and lesions in the brain. Additionally, degenerative diseases and autoimmune conditions may also result in cranial lesions. Accurate diagnosis typically requires imaging studies and clinical evaluation to determine the underlying cause.

What is hyperemic heterogeneous lesion?
A hyperemic heterogeneous lesion refers to an area of tissue that appears red ("hyperemic") and has varying consistency or composition ("heterogeneous") on imaging studies such as MRI or CT scans. This type of lesion can be caused by a variety of factors including inflammation, infection, or tumor growth. Further evaluation and testing are usually needed to determine the underlying cause of the lesion.
What body cavity contains and protects the brain?
The brain lies within the cranial cavity which is inside the larger dorsal cavity
Which cranial nerve if damaged causes inability to see close?
The cranial nerve that, if damaged, can cause an inability to see close objects is the oculomotor nerve (cranial nerve III). Damage to this nerve can affect the movement of the eye muscles responsible for changing focus and adjusting the shape of the lens to see objects up close.
What cause skull plates to shift in adults?
Effective and proper movement of the cranial plates is indeed critical for and proper brain function
What cranial nerve is associated with the eye and what damage does it cause?
The cranial nerve associated with the eye is the oculomotor nerve (Cranial Nerve III). Damage to this nerve can result in symptoms such as ptosis (drooping of the eyelid), strabismus (misalignment of the eyes), and difficulties in eye movements, leading to double vision. Additionally, it can affect pupil constriction, resulting in a dilated pupil that does not respond to light.
Can in infection cause a lesion on the brain?
Well since a lesion is a cut or wound, no. Not unless it was an infection that has hard pieces that could cut the brain.
What does bilateral innervation of cranial nerves mean?
Cranial nerves that have a motor function tend to be bilaterally innervated. In other words, the right accessory nerve (XI) receives input from both the right and the left motor cortex. The same goes for the left accessory nerve.This is a handy advantage in strokes, since upper motor neurone lesions must therefore be bilateral in order to cause a deficit.The one major exception to this rule is the facial nerve (VII). Only the forehead muscles are bilaterally innervated, so even a unilateral upper motor neurone lesion can cause mouth drooping, etc. However, this can still often be differentiated from a lower motor neurone lesion, which will not spare the forehead.
What is angioectasias?
Angioectasia is a venous lesion that requires cauterization; a Dieulafoy's lesion and arteriovenous malformation may cause arterial bleeding, which requires clipping or laparotomy.
What drugs cause damage to 8 cranial nerve?
Gentamycon, Vancomycin
what does the bone lesion cause?
A bone lesion is an anomaly in the structure of a bone. They can occur in any part of the body. Check out more here: http://www.ehow.com/about_5072414_bone-lesion.html
What Can cause irreversible damage to the auditory branch of the eight cranial nerve?
cephalosporins
What symptoms may occur when an acoustic neuroma presses on the surrounding cranial nerves?
Compression of the fifth cranial nerve can result in facial pain and or numbness. Compression of the seventh cranial nerve can cause spasms, weakness or paralysis of the facial muscles
What part of the brain controls thirst?
Can a brain lesion cause excessive thirst even if the pituitary gland is normal? Also where would the lesion be located?
What causes 17.6 cm lesion on the liver?
A 17.6-cm lesion on the liver could be caused by a number of things. Cancer may be a cause. Non-cancerous possibilities include adenomas and hemangiomas.

Which lesion in a coronary artery do physicians normally consider higher risk proximal lesion or distal lesion?
Proximal lesion
What is pre-malignant lesion?
A pre-malignant lesion is a lesion that, while not cancerous, has strong potential for becoming cancerous. An example would be a callous-like area between the cheek and gum where someone who chews tobacco keeps the tobacco plug. Given enough time, that area will often turn cancerous. Sometimes a chronic irritation from an ill-fitting denture can be called pre-malignant. The cause of a pre-malignant lesion should be determined and eliminated, and the lesion should usually be biopsied to make sure it is not cancer.
