Lesions on the brain & Spinal Tap came back fine.

Postby blondie33 » Fri Aug 03, 2012 7:43 pm

I'm very confused as to why I have 9 White Matter Lesions on my Brain but my Spinal Tap came back fine. I'm very scared at a possible MS diagnosis. What are some other possible reasons why I have lesions on my brain?

Hi blondie,

Welcome, although I'm truly sorry to hear they've found lesions on your brain. There are many, many, many reasons for brain lesions besides MS, and some of them are truly benign. I did a quick google search and found a pretty comprehensive site with info about brain lesions, so I'll add the link and some quotes from the MANY pages at the site.

There are several specific diseases that can cause lesions (like lupus), although they're not enumerated under the "infectious" category at the site. Different types of brain lesions give different presentations that help to identify their causes - MS lesions often present with specific shapes and in specific locations. My brainful of lesions gave me an instant diagnosis even before I got the spinal tap (which DID confirm MS).

There is lots of information here at ThisIsMS also, so make yourself at home and start reading. :smile: Most questions have come up here before, so you can also try the "search" function at the top. Good luck!

P.S. Even if you have MS, it's not the end of the world. Many of us have had it for years and are doing okay. :smile:

Here's a link to the site I mentioned and some quotes from it:

Brain Lesions Facts
Brain lesions (lesions on the brain) refers to any type of abnormal tissue in or on brain tissue.
Major types of brain lesions are traumatic, infectious, malignant, benign, vascular, genetic, immune, plaques, brain cell death or malfunction, and ionizing radiation. Other chemicals and toxins have been associated with brain lesions as well.
Brain lesions have many different causes that are related to the types listed above.


Brain Lesions Causes
From the above description of brain lesion types, it is evident that the different types are arranged, in general, according to different mechanisms that lead to brain cell changes which produce various brain lesions. The causes, however, can be further categorized. The following is a list of causes containing more specific subsets and descriptions:

Trauma: penetrating or blunt. Blunt trauma may be further subdivided to include with or without skull fracture. Trauma results in damaged or destroyed brain tissue with immediate and/or delayed (hours to days, usually) symptoms.

Infectious: Brain lesions caused by a wide variety of pathogenic agents ranging from viruses, bacteria, fungi, and parasites. Some may develop symptoms quickly over hours to days (such as in viral and bacterial meningitis) or over many years (such as in the parasitic infection Cysticercosis).

Malignant: Malignant brain lesions subtypes are termed "primary" if they arise from the brain tissue cells (such as gliomas and medulloblastomas) and "secondary" if they originate in other body organs and spread (metastasis) to the brain (such as lung, breast, and colon cancers). Secondary brain lesions are more common than primary brain lesions. Some lesions develop fairly fast (weeks to months), while others may develop more slowly. In addition, malignant lesions are often graded, which means they are assigned a number (I, II, II or IV) based on their appearance under a microscope. Grade I tumors are less aggressive and tend to grow and spread more slowly, while grade IV tumors are the highly aggressive and tend to grow and spread more rapidly.

Benign (non-cancerous): Brain lesions composed of abnormally growing cells which are non-cancerous (though a rare few may contain some cancer cells, mainly grade I). They may cause symptoms if they become large and compress other normal brain tissue or interfere with the blood supply to the brain. They usually develop slowly (for example, meningiomas).

Vascular: Three subtypes of vascular brain lesions exist; 1) arteriovenous malformations (weak vascular areas that may leak or burst, causing blood to leak into brain tissue), 2) abnormal growth of vessels in the brain (hemangioblastomas associated with von Hippel-Lindau disease), and 3) the most frequently encountered vascular problem, strokes (also termed cerebral vascular accidents or CVA's). Most strokes are caused by clots (about 85%) which cause brain cell damage or death by reducing or cutting off the blood supply to areas of the brain. Except for the long-term development of diseases like von Hippel-Lindau, vascular brain lesions generally produce symptoms within minutes to hours.

Genetic: Errors in human DNA or certain DNA sequences in the genetic makeup of some individuals can lead to brain lesions, such as neurofibromatosis or familial British dementia. Most of these lesions develop over years.

Immune: The individual's immune system mistakenly attacks and attempts to destroy brain tissue components, such as myelin (a sheath surrounding nerve cells). The resulting scar tissue can be seen in multiple sclerosis, for example. These types of lesions usually progress in development over years.

Brain cell death or malfunction: The cause of certain brain lesions, like those seen with Parkinson's disease, are due in part to the malfunction and death of brain cells that produce dopamine. However, the underlying cause may be related to genetics, toxic exposures, or various other combinations of potential causes. Development usually progresses over years.

Plaques (deposits of substances in brain tissue): Deposits of materials such as Lewy bodies, amyloid plaques, and neurofibrillary tangles or bundles in brain tissue are associated with several diseases, most notably Alzheimer's disease. However, it is not clear whether the deposits are the primary cause or if they are the secondary results of an underlying (and as of yet) unidentified cause. Development usually progresses over years.

Ionizing radiation:X-rays, gamma rays and other types of radiation, when intense enough or if acquired sequentially in high levels, can disable and destroy brain cells, as well as other cell types.


Lesion Definition
Lesion: a lesion can be almost any abnormality involving any tissue or organ due to any disease or any injury.

There are, not surprisingly, many types of lesions. There are also a number of different ways of classifying and naming lesions. Lesions can, for instance, be categorized according to whether or not they are caused by cancer. A benign lesion is non-cancerous whereas a malignant lesion is cancerous. For example, a biopsy of a skin lesion may prove it to be benign or malignant, or evolving into a malignant lesion (called a premalignant lesion).

Lesions can be defined according to the patterns they form. For example, a bull's-eye or target lesion is one that looks like the bull's eye on a target. A coin lesion is a round shadow resembling a coin on a chest X-ray. It, too, is usually due to a tumor.

Lesions can also be categorized by their size. A gross lesion is one that can be seen with the naked eye. A microscopic or histologic lesion requires the magnification of a microscope to be seen. The basis of sickle cell disease is a molecular lesion, one that is not even visible with a microscope but is only detectable on the molecular (protein or DNA) level.

Location is another basis for naming lesions. In neurology, a central lesion involves the brain or spinal cord, i.e., the central nervous system. A peripheral lesion involves the nerves away from the spinal cord and does not involve the central nervous system.

There is a virtually endless assortment of lesions in medicine: primary lesions, secondary lesions, impaction lesions, indiscriminate lesions, irritative lesions, etc. Many are named for people including the Armanni-Ebstein lesion, a Bankart lesion, a Blumenthal lesion, and so on.

Dx'd with MS & HNPP (hereditary peripheral neuropathy) 7/03 but must have had MS for 30 yrs before that. I've never taken meds for MS except 1 yr experiment on LDN. (I found diet, exercise, sleep, humor, music help me the most.)

Thanks so much for your response. I really appreciate it. I have a follow up appt. with my neuro on October 25 so hope it goes well
