What is the history of Tarlov Cyst?

I’m not sure of the history

See Tarlov Cyst Disease

Dr Tarlov diagnosed it in 1938

Tarlovs were discovered in the early 1900s,. Or atleast that is when they were named. Name given to them by a Dr Tarlov. In recent textbooks they are given a whole chapter to themselves, before they receive a paragraph.

I believe it was a man named tarlov who was a doctorate in 1937 who actually stated that these cysts were incidental finding and did not cause pain. He was very wrong

Isadore Max Tarlov, an early neurosurgeon, made several important contributions to the field of spine surgery. He described sacral perineural cysts, now known as Tarlov cysts. Dr. Tarlov also introduced the knee-chest patient position to facilitate exposure and hemostasis in lumbar surgery. In addition, he developed the use of fibrin glue in nerve repair.

Tarlov was a doctor who discovered the cysts in 1938.

Isadore M. Tarlov, M.D., in 1938

Dr. Isadore Max Tarlov is especially remembered for his 1938 description of the eponymous perineural
'Tarlov cyst', discovered during an autopsy study. (Tarlov IM: Perineurial cysts of the spinal nerve roots,
Arch Neurol Psych 40:1067–1074, 1938).
Unfortunately, his first publication is still rememberd, and which appeared in the textbooks. The words "not of clinical significance" or "incidental finding" are still referred to among physicians, and with these words still patients are send off home, without proper examination and diagnosis (with the mere few). BUT DID TARLOV WROTE THAT THEY WERE INCIDENTAL FINDINGS AND OF CLINICAL SIGNIFICANCE? NO - HE DID NOT

What is the definition of an incidental finding? An incidental finding is "a finding concerning an individual research participant who has potential health or reproducivity interest and is discovered while conducting research, but falls outside the scope of the study" (Wolf, Managing Incidental Findings in Human Subjects Research, J Law Med Ethics, 2008).
The tarlov study involved an autopsy study of the filum terminal of 30 adult subjects, in which he had found perineural cysts. Cysts that were already found by Marburg, who described 4 cases (1902) of cysts of the spinal ganglia. The cysts were solitary in 3 cases and several in the fourth. Hinrichs (1932) recorded a case in which 3 cysts occurred on the posterior thoracic and lumbar roots, in the area of crossing the root and ganglion. The exact location of origin of the cysts were not determined by either in the reported cases.
Dr. Tarlov found this experience worth capturing, especially since in these cases it was possible to determine the place of origin of the cysts.
YOU CAN'T REALLY CALL THE DISCORVERY OF THESE CYSTS INCIDENTAL, RESEARCH INVOLVED 30 CADAVERS OF ADULTS AND IN WICH THESE CYSTE WERE FOUND IN 5 OF THEM.

What did dr. Tarlov find out more in his first study?
Tarlov: as far as I was aware of, no symptoms or signs referring to cysts. Although the cysts did not appear to have clinical significance in these cases, one wonders whether they are not responsible for the discomfort in
certain cases of sciatica or nerve root pain in which other pathological causes are excluded. This awaits
further studies with clinical and pathological correlations.
Histological examination of the cyst showed no evidence of recent or ancient bleeding, which, if present, would have explained a traumatic origin. In cases where nerve fibres or ganglion cells completely or partially surrounded the cyst, EVIDENCE OF DEGENERATIVE CHANGES WAS PRESENT. Disintegration of myelin shells and nerve fibers was seen in Refuse-Pal and Gros-Bielschowsky preparations and cresyl violet spots revealed chromatosis (a reactive change that occurs in the cell body of damaged neurons) of ganglion cells.
Accumulations of phagocytes (white blood cells) filled with fat or blood pigment occurred, and mucicarmine
revealed a few drops of mucine in large round cells. THERE WAS FAILURE OF NERVE CELLS IN THE CORRESPONDING GANGLION, with prolefartion (growth) of fibroblasts and formation of connective tissue scars. (fibroblasts: cells that produce collagen fibers, these are non-stretchy fibers that ensure firmness of our tissues. In addition, they also create other components of the soil substance, or extracellular matrix, in the connective tissue).
AGAIN, YOU CANNOT TALK ABOUT CLINNICALLY NOT RELEVANT, GIVEN TARLOV'S REACTION, DEGENERATIVE AND NERVE CEL DEATH, AND NECESSARY FURTHER STUDIES.

In 1938 publiceerde Isadore Max Tarlov, neurochirurg uit
Connecticut, voor het eerst over deze Tarlov cysten (Tc’s)
nadat hij deze ontdekte in een studie op menselijke
kadavers. Zijn eerste bevindingen waren, dat dit “banale
bevindingen” waren. In opvolgende studies kwam Tarlov
met de conclusie dat deze cysten het "ischiassyndroom"
kon veroorzaken. De “goedaardige bevindingen” werden
vanaf toen beschreven als een bron van radiculaire pijn.
Ook de Nederlandse prof. G. Padberg, zenuwarts te
Maastricht, schreef reeds op 10 oktober 1959 in het Ned.
T. Geneeskunde103. II. 41, over “Perineurale Wortelkystes”
waarvan hij toen al argumenteerde dat het door artsen
over het algemeen onvoldoende bekend was dat deze
lage rugpijn, ischalgieën en neurologische stoornissen
kunnen veroorzaken.

Tarlov or perineurial cysts are lesions of the nerve root most often found in the sacral region. They were first discovered serendipitously by Tarlov in 1938 during his autopsy studies of the filum terminale at the Montreal Neurological Institute.37 Since his seminal report, more than 100 cases of symptomatic Tarlov cysts have been published in the literature.* The advent of computed tomography (CT) and magnetic resonance imaging (MRI) has enhanced our ability to recognize them as a cause of sacral neurologic dysfunction.

They were discover in corps / autopsy by a doctor named Isidore tarlov
