How is Tarlov Cyst diagnosed?

First important step is to have an MRI of your sacral region. I had one general, and an additional with contrast to ensure there were no other ailments in my spine other than the cyst. Unfortunately many people have multiple problems in their spine which can exasperate the symptoms of the Tarlov cyst. Diagnosing these are essential for proper treatment. Additional tests which help narrow down if the cyst is the cause or other pre-existing conditions is to have a nerve block done on the sacrum to see how symptoms improve. Finally, I had basic tests done on my SI joints, and leg nerves to make sure that symptoms were related to nerves and not joints. This is pretty standard for the process of eliminating other diseases first.

It is recognized on MRI, but many doctors note them as "incidental" if at all. Many people have them and have no symptoms, but it depends which nerve is affected or if there is a cluster pressing together. I have several dozen of them at all levels of my spine, so my symptoms are wide ranging.

They diagnosed mine with an exploratory full back MRI. It was noticed at about 1cm in size and fills up with spinal fluid which makes the casing stick out quite well in the MRIs

I came in for pain in tailbone area, they thought my tailbone was broken. We did X-rays and saw nothing but bone issues, so then we did MRI which led us to bone scans. Then I've had 7 neurosurgeons review to a conclusion of tarlov cysts.

It's my opinion, based on research, reading abut how others were diagnosed, as well as my own experience, that Tarlov cysts can be diagnosed by means of a CT Scan, and/or, and more accurately, and MRI, but only if the professional reading the images of either, or both has the knowledge of what to look for. It is essential for those having been diagnosed with a Tarlov cyst to see, an "experienced" Neurosurgeon, and I emphasize experienced, because being a member of support groups on Facebook for people with Tarlov cysts, I have heard some "HORRIFYING" stories from people who have had procedures done by neurosurgeons who say they're experienced, but honestly shouldn't be allowed to treat animals for heartburn. If a doctor is experienced with Tarlov cysts, like my orthopedic doctor who discovered mine on an MRI of my Lumbosacral spine, just experience of knowing what they are looking at, along with your symptoms, which would most likely be the reason for them doing an MRI, is pretty much all they need.

The best way to confirm is thru MRI. Most are misdiagnosed. Most patients are told they are non symptomatic. I would avoid MRI with contrast since the contrast can agravate other spinal problems.

MRI will show cysts growing on top of your nerve roots. They will be called “Perineural cysts” and likely reported as “probable insignificance”. You have to read your report and ask questions and report your symptoms. The cysts should be individually measured as they will grow bigger over time and can cause permanent nerve damage and disability.

Most fysicians can diagnose from looking at the MRI (important is to also have sacral nerveroots scanned in axial and coronal view to determine nervecompression by cysts on other nerves as well) and the symptoms of the patient. How an MRI should be done: https://sosnl.nl/medici/diagnosestelling-eng When doubtfull some may want to conduct a nerve block or a cortisone injection, but ...... Often a diagnostic nerve root block or a therapeutic blockade with corticosteroids is suggested to make the diagnosis, however there is a risk of puncturing the cyst because the nerve root is dilated, which can damage the nerve fibers in the cyst or cyst wall. infection, bleeding, or a dural leak. It should be noted that the use of epidural steroids in radiculopathies and risk of rare side effects such as arachnoiditis, usually as a result of damage involving the introduction of foreign substances into the subarachnoid space. ESI (epidural steroid injection) is more used in sciatica when there is a substantial inflammatory component (especially if it is acute) but less useful when there is a predominantly compressive radiculopathy. Consequences of Arachnoiditis is chronic, persistent pain that is mainly neurogenic (nerve generated) and thus difficult to treat. This pain is transmitted through the dorsal root ganglia in the spinal cord, resulting in damage to the autonomic and central nervous system, and can even cause changes in cerebrospinal fluid dynamics due to an uncommon complication of communicating hydrocephalus. A number of epidural steroids contain excipients such as benzyl alcohol, a solvent for various compounds. In view of the weakness of the connective tissue of the nerve roots, one should therefore be careful with this. This is discussed in detail in “the arachnoiditis syndrome”, as well as research results on the usefulness of epidural injections. As multiple Tarlov cysts – larger, smaller and valveless valve cysts – can often co-occur in the same patient and cause neurological symptoms, the minimally invasive procedure of NCS/EMG can thus replace the more invasive diagnostic block to avoid potential complications inherent in interventional procedures. However, once the diagnosis is made, treatment options are limited as there is no consensus on the choice of treatment. An advantage of NCS/EMG, is that it is less invasive for the patient. But also know what you are measuring. Typically, a needle EMG is performed from myotomes L3 to S1 to determine the severity of radiculopathies. In case of symptomatic Tarlov (perineural) cysts, this is insufficient, the Tarlov cysts are most commonly found on nerve roots S2 to S4, so more extensive testing is necessary. Se next links for protocol on needle EMG/NCS: https://sosnl.nl/medici/protocol-naald-emg When patients are complaining about headaches, neckpain, blurry sight or loss of visual field, they should be examined for papilloedema and preferably also a pressure measurement. Symptoms in Tarlov Cyst and Hypertension Syndrome patients may resemble Idiopathic Intracranial Hypertension. IIH, INPH (Idiopathic Normal Pressure Hydrocephalus) and symptomatic TCs are CSP dysregulation disorders. Several cases with an association between elevated intracranial pressure and Tarlov cysts have been described. IIH occurs mainly in young obese women and is associated with papilloedema and visual problems. Bortoluzzi et al. found that in these patients the nerve root sheaths in the spinal canal were clearly dilated. In addition, several other authors have reported radiculopathy in patients with IIH. Tarlov cyst patients do not always have papilloedema, however papilloedema is no longer necessary to make the diagnosis. And the pressure is not always increased, with clear symptoms. There are no clear reference values ​​for CSP (cerebro spinal pressure) and there are controversies about the OP cut-off value for the diagnosis of IIH (> 20 cm H2O in non-obese and 25 cm H2O in obese patients). It is well established that hydrostatically lowering pressure (HP) by external lumbar CSF drainage or the administration of acetazolamide can alleviate the symptoms of sacral Tarlov cysts. A normal IP is based on 5-15 CM H2O in adults, but most doctors still think you only can have symptoms when pressure is above 25 cm H2O. Larger cysts can act as a buffer system for CSF pressure. Tarlov cysts are filling, expanding CSF containers that may initially act to prevent a further increase in pressure. In some cases, during the development of a Tarlov cyst, narrowing of the cyst neck may occur due to proliferation of spinal arachnoid granulations around the dorsal nerve roots. Such proliferation is in response to an increase in CSF pressure. A narrow neck creates a one-way valve system that allows CSF to enter the cyst, but the limit significantly limits outflow. Under these conditions, the pressure in the cyst rises to a level higher than the pressure in the spinal canal and axons are compressed even more than in communicating TCs. https://www.researchgate.net/publication/333025384_Symptomatic_Tarlov_cysts_are_often_overlooked_ten_reasons_why-a_narrative_review http://www.arachnoiditis.co.uk/index.php/information/medical-papers-2/124-the-arachnoiditis-syndrome-dr-sarah-smith https://www.dovepress.com/the-link-between-idiopathic-intracranial-hypertension-fibromyalgia-and-peer-reviewed-fulltext-article-JPR https://www.researchgate.net/publication/325874274_Spinal_Fluid_Evacuation_May_Provide_Temporary_Relief_for_Patients_with_Unexplained_Widespread_Pain_and_Fibromyalgia “Idiopathic intracranial hypertension is not idiopathic: proposal for a new nomenclature and patient classification” https://jnis.bmj.com/content/early/2019/12/01/neurintsurg-2019-015498.abstract

https://sosnl.nl/overdruksyndroom/tarlov-cysten De diagnose wordt gesteld met behulp van een MRI-scan van de onderkant van de wervelkolom. Hierop zijn de cysten zichtbaar maar blijven vaak onopgemerkt omdat artsen anno 2019 nog vaak onbekend zijn met deze aandoening. Mensen met het overdruksyndroom of Tarlov-cysten lopen vaak al jaren rond met invaliderende klachten alvorens de diagnose gesteld wordt. Dit komt omdat veel van de symptomen ook voorkomen bij andere aandoeningen. De diagnose wordt doorgaans gesteld op basis van: De klachten van de patiënt, waarbij langdurig bestaande, onverklaarbare en moeilijk te behandelen pijnklachten centraal staan. Een pinpriktest waarbij met een naald in de romp en ledematen geprikt wordt om gevoelsstoornissen vast te stellen. Een MRI van de ruggengraat waarop Tarlov-cysten waargenomen kunnen worden. Een elektromyografie (EMG) van de benen en het bekken waarop de elektrische activiteit van de spieren en zenuwen gemeten wordt.

MRI scans are the best option for imaging TC's.

The diagnosis is made using an MRI scan of the bottom of the spine. The cysts are visible on this, but often go unnoticed because doctors in 2019 are often still unfamiliar with this condition. People with overpressure syndrome or Tarlov cysts often have disabling complaints for years before they are diagnosed. This is because many of the symptoms also occur in other conditions. The diagnosis is usually made on the basis of: The patient's complaints, in which long-standing, unexplained and difficult to treat pain complaints are central. A pin prick test in which a needle is pricked into the trunk and limbs to determine sensory disturbances. An MRI of the spine showing Tarlov cysts. An electromyography (EMG) of the legs and pelvis measuring the electrical activity of the muscles and nerves.

First of all, the imaging résonnence magnetic , then a puncture of cerebrospinal fluid in the cyst. If this puncture allows a net improvement even if it is only for a few weeks, then the cyst is symptomatic and the diagnosis is confirmed.
