Perineural cysts\n\nDefinition\n\nPerineural cysts (also called Tarlov cysts) are abnormal fluid-filled sacs located in the sacrum, the base of the spine.\n\nDescription\n\nPerineural cysts appear to be dilated or ballooned areas of the sheaths that cover nerve roots exiting from the sacral area of the spine. The spaces or cysts created by the dilated sheaths are directly connected to the subarachnoid area of the spinal column, the area through which cerebrospinal fluid flows. Many people have perineural cysts but no symptoms at all; in fact, the majority of people with these cysts are completely unaware of their existence. However, when conditions cause these perineural cysts to fill with cerebrospinal fluid and expand in size, they can begin to compress important neighboring nerve fibers, resulting in a variety of symptoms, including pain, weakness, and abnormal sensation.\n\nDemographics\n\nMore women than men develop perineural cysts.\n\nCauses and symptoms\n\nA variety of conditions that can increase the flow of cerebrospinal fluid may cause perineural cysts to expand in size, creating symptoms. Such conditions include traumatic injury, shock, or certain forms of exertion (such as heavy lifting) or exercise. Prolonged sitting or standing may cause cysts to fill and retain fluid. Other research suggests that herpes simplex virus can cause the body chemistry to become more alkaline, which predisposes the cerebrospinal fluid to fill the perineural cysts, thus prompting the advent of symptoms.\n\nThe symptoms of expanding perineural cysts occur due to compression of nerve roots that exit from the sacral area. Symptoms may include back pain and sciatica, a syndrome of symptoms that occur due to compression or inflammation of the sciatic nerve. Sciatica results in burning, tingling, numbness, stinging, or electric shock sensations in the lower back, buttocks, thigh, and down the leg to below the knee. Severe sciatica may also result in weakness of the leg or foot. Other more severe symptoms of perineural cysts include loss of bladder control and problems with sexual functioning.\n\nDiagnosis\n\nBecause most perineural cysts don't cause symptoms, most perineural cysts are never diagnosed. When symptoms do develop that are suggestive of perineural cysts, MRI will usually demonstrate their presence, and CT myelography (a test in which dye is injected into the spine) may demonstrate the cerebrospinal fluid flow between the spinal subarachnoid area and the cyst.\n\nTreatment team\n\nNeurologists and neurosurgeons usually treat individuals with perineural cysts. A urologist may be called in to consult with individuals whose cysts are interfering with bladder or sexual functioning.\n\nTreatment\n\nAlthough using a needle to drain fluid from perineural cysts can temporarily relieve their accompanying symptoms, eventually the cysts will refill with cerebrospinal fluid and the symptoms will recur. Similarly, steroid injections can provide short-term pain relief. Pain may also be temporarily controlled by injecting the cysts with fibrin glue (a substance produced from blood chemicals involved in the clotting mechanism). Using diet or dietary supplements to decrease the body's alkalinity may prevent perineural cysts from filling with more fluid. Medications used to treat chronic nerve-related pain (such as anticonvulsants and antidepressants) may be helpful.\n\nWhen pain is intractable despite a variety of interventions, or when weakness or other neurological symptoms become severe, surgery to remove the cysts may be necessary. This is the only permanent treatment for perineural cysts; once removed, they very rarely recur.\n\nPrognosis\n\nMost individuals with perineural cysts have no symptoms whatsoever. Those who do have symptoms run a risk of neurological damage if the cysts continue to compress nerve structures over time. Individuals who undergo neurosurgery to remove the cysts usually have an excellent outcome, with no cyst re

The thecal sac is the overall name for the covering of your spinal cord andthe nerves where they leave your spinal cord. The first part of your report says that you have a slipped disc (disc protusion) which is pressing in a forwards/backwards (anterior/posterior) manner on the spinal cord. \nThe second part says you have another slipped disc pressing (effaced means touching/pressing on) on the nerve as it leaves your spinal cord.\n\nNeither of these is really dangerous, just painful. You probably need to see a back specialist though to sort out treatment.

are you talking about a piloniadal cyst?  if so I have had this for years as well.  I had it removed and it came back and I have to have it removed again.  bloody sore ain't even the words for this pain!!!  I feel for ya if it is the same thing you are talkin about!

Probably a benign cyst and nothing to worry about, but its always wise to get these things checked out by a doctor :D

Could be a cyst or bladder infection, you have to see a doctor

Have you been told by your doctor that the problem is cysts?\n\nThe most common cysts are those of the skin and mucous membranes. A sebaceous cyst occurs when a sebaceous gland, the tiny oil gland at the base of each hair root, becomes plugged. Ordinarily this plugging just results in a blackhead, or a pus-filled pimple if the blackhead becomes infected. Occasionally however, the pimple does not break and the swelling becomes entrapped beneath the skin. Sebum (oil from the sebaceous gland) continues to flow into the sac that forms in the cavity, and the cyst grows to the size of a marble or larger. Sebaceous cysts can occur on any part of the body where there is hair.\n\nContact your doctor and ask if the same steps for treating acne will help your problem with the cysts, that are under your arm?\n\n- Gently wash the affected areas once or twice daily with the cleanser of your choice.\n\n- Use an acne cream or lotion. Start with over-the-counter lotions that contain benzoyl peroxide, sulfur, resorcinol, or salicylic acid as the main ingredient.\n\n- If you use moisturizer, choose one that is labeled noncomedogenic (this has been tested and found not to cause pimples).\n\n- Don't squeeze your pimples. Your doctor can show you how to lance them.\n\n- Practice stress management techniques. Stress can worsen acne or help bring on outbreaks.\n\nYour doctor may recommend an acne ointment or cream, oral antibiotics, or both. Prescription lotions, creams, or gels containing vitamin A acid (tretinoin, commonly called Retin-A) help stop pimples from forming by prventing dead skin cells from sticking to the wall of the hair follicle. Antibiotics kill bacteria, which contribute to inflammation.\n\nI'm hoping this information helps you.\nGood luck

where do you have the lump?

I actually had this too a few years ago.  It was a fluid filled cist.  They were going to operate to remove it but instead they stuck a big needle in there and it drained right out.  Its been fine ever since.  It was also the size of a pea and times if I used my hands a lot or bumped it it would hurt more.

anywhere near the sciatic nerve, which branches off the spinal column near the hips and runs down the back side of both legs, but i like it!

I would agree that it's ganglion cyst.  It sounds ridiculous, but I've seen many people use a sizable book to smack it fairly hard and they go away....

I think you mean cauda equina... I'm not sure why this is in the 'Geography' category since medicine would be more appropriate.\n\nI found a few links that might be helpful:\n\nCauda equina is rare disorder affecting the bundle of nerve roots at the lower (lumbar) end of the spinal cord is a surgical emergency. An extension of the brain, the nerve roots send and receive messages to and from the pelvic organs and lower limbs. Cauda equina syndrome (CES) occurs when the nerve roots are compressed and paralyzed, cutting off sensation and movement. Nerve roots that control the function of the bladder and bowel are especially vulnerable to damage. \n\nIf you don't get fast treatment to relieve the pressure, CES may cause permanent paralysis, impaired bladder and/or bowel control, loss of sexual sensation and other problems. Even if the problem gets treatment right away, you may not recover complete function. \n\nCES may be caused by a ruptured disk, tumor, infection, fracture or narrowing of the spinal canal. It may also happen because of a violent impact such as a car crash, fall from significant height or penetrating (i.e., gunshot, stab) injury. Children may be born with abnormalities that cause CES.

If your family dr did the gyn exam, see a gynecologist. Pain in this area can be caused by cysts, infection, scar tissue, endometriosis, urinary tract infections. If the pain is only on 1 side, infection or inflammation in the colon can cause this although usually there are other symptoms.\n\nIf you saw a gyn dr then I'd get another opinion and consider a pelvic  ultrasound to look for cysts.

"It doesn't sound like an STD, more likely a simple furuncle (large pimple). Also, some people have a minor congenital anomaly called a pilonidal cyst, which typically occurs in the location you describe; it can get infected and cause symptoms like you describe. More seriously, you might have a perirectal abscess. The latter occurs when an infection starts inside the rectum and borrows through to the surface near the anus. Even though it is improving, you should see a health care provider. You may need an antibiotic and, depending on the exam findings, further tests to check out the abscess possibility.\n\nGood luck-- HHH, MD"\n\n"Sounds like a pilonidal cyst. My husband has had two bouts with these, and two surgeries to remove it. Sometimes they drain themselves or can be drained by a doctor. His cyst would drain, heal, then another area would open up, and drain and then heal. A cycle continued for a long time. Do a search on the cyst.  One more comment. His did not look like a growth, but as an opening in the tissue. I am sure the doctor can give you more insight on this. Good luck."

the femoral cutaneous nerve could be pinched at the pelvis...meralgia paresthetica maybe

Lipomatosis is a condition marked by the excessive deposit of fat in a localized area. Epidural means located over or on the dura.  Dura is a fibrous connective tissue membrane, the outermost of the meninges covering the spinal cord (dura mater spinalis) and brain (dura mater cerebri or dura mater encephali).\n\nI do not have any more information on it, unforunately.  Contact your doctor and ask him about the condition and why it was not mentioned to you during your visit.  If you do not receive a satisfactory answer, then get a second oppinion.
