Lumbar synovial cyst histology

Symptomatic lumbar synovial cysts (LSCs) are a rare cause of degenerative narrowing of the spinal canal, with thecal sac or nerve root compression. True synovial cysts have a thick wall lined by synovial cells, containing granulation tissue, numerous histiocytes, and giant cells Lumbar synovial cysts of the spine: an evaluation of surgical outcome Spinal cysts are commonly found at the L4-L5 level, the site of maximum instability. MRI is the tool of choice for diagnosis. The etiology is still unclear, but underlying spinal instability has a strong association for formation of spinal cysts and worsening symptoms Histology of 'synovial cysts' of the spine shows varied types of cyst; a large proportion are not synovial-lined cysts, but rather show pseudocystic degenerative changes of the ligamentum flavum, often associated with very characteristic finely granular calcifications and a foreign-body giant-cell reaction

Surgical treatment of spinal synovial cysts is safe, effective and ensures a long-lasting effect. Surgical treatment is indicated in patients in whom the clinical symptoms correlate with the presence of synovial cyst in imaging studies and do not resolve after conservative treatment Spinal synovial cyst: Soft tissue mass located extradurally along medial border of degenerated facet joint. Usually at L4-5, rarely in cervical or thoracic spine. Filled with clear or xanthochromic fluid. Causes back and radicular pain. Rarely results in cauda equina syndrome ( Pain Physician 2012;15:435 Histology of 'synovial cysts' of the spine shows varied types of cyst; a large proportion are not synovial‐lined cysts, but rather show pseudocystic degenerative changes of the ligamentum flavum, often associated with very characteristic finely granular calcifications and a foreign‐body giant‐cell reaction [Synovial cysts and synovialomas of the lumbar spine.

lumbar 4-5 level 20). The ganglion cyst is believed to be distinguished from the synovial cyst by the lack of a synovial lining. The ganglion cyst is not connected to the synovial cavity, and is usually filled with viscous fluid. Ganglion cysts often contain an amorphous proteinaceous material and the cyst wall is composed of loose, but well. Diagnosis and Safe Excision of Lumbar Synovial Cysts and Accompanying Pathology: A Perspective. Epstein NE(1). Author information: (1)Professor of Clinical Neurosurgery, School of Medicine, State University of New York at Stony Brook, New York, United States Most spinal synovial cysts occur in the lumbar region at vertebrae L4 or L5. For a point of reference, L4 and L5 are located at a level right below the belly button. This area is considered to have a significant amount of spinal instability, which may be related to the formation of cysts The authors report 8 cases of patients with synovial cysts (3 cases) or diverticuli (5 cases) of the lumbar joints, compressing the sciatic roots. They describe the radiological aspects of the two sides of the degenerative pathology of the posterior articular processes, which are relatively unrecognized (14 cases in the literature)

Background: Lumbar synovial cysts are often not sufficiently diagnosed prior to spine surgery. Utilizing both MR and CT studies is critical for recognizing the full extent/severity of these lesions Lumbar synovial cysts are cystic dilatations of synovial sheaths that directly emanate from facet joints and extrude into the spinal canal No cyst or tumor is seen. DIAGNOSIS: Dural mass: synovial cyst. Extradural tissue: no significant abnormality seen. Discussion. It is important not to forget synovial cysts as a cause of peripherally enhancing masses in the extrathecal space, anywhere along the spinal canal, but particularly in the lower lumbar and midcervical regions Ganglion and synovial cysts are benign lumps caused by a buildup of fluid in a tendon sheath or joint capsule. They most commonly show up on the top of the wrist, but may also affect the feet or the spine. Spinal cysts are more common in people over the age of 50. The cause of spinal cysts is. Synovial cyst.

However, since the joint pathology that caused the original synovial cyst is still present, the cyst can re-form at a later date. Decompression with Spine Fusion Surgery. The most reliable treatment method for a synovial cyst is to remove the cyst and then fuse the joint While no synovial cyst lining was observed in our histopathology, confirmatory synovial linings in pathology reports have been sparse in previous case series, with up to 71% of true synovial cysts. Therefore, we sought to characterise the histological features of tissue submitted as 'synovial cysts' of the spine.Resected specimens of the spine labelled 'synovial cysts' and 'lumbar cysts' were histologically evaluated and classified on the basis of histopathological features.

A synovial cyst of the spine is a fluid-filled sac that develops along the spine. It's the result of degeneration of a facet joint of the spinal vertebrae. Most synovial cysts develop in a part. Conclusion: Histology of 'synovial cysts' of the spine shows varied types of cyst; a large proportion are not synovial-lined cysts, but rather show pseudocystic degenerative changes of the ligamentum flavum, often associated with very characteristic finely granular calcifications and a foreign-body giant-cell reaction Anatomy of Synovial Cysts and Radiological Appearance on MR. Pathoanatomically, synovial cysts are comprised of cystic dilatations of synovial sheaths that have directly extruded from the overlying facet joints into the spinal canal due to disruption of the facet joint capsule [].[] On T2 weighted MR images, SC frequently demonstrate a hypointense outer perimeter indicative of an enlarged.

Histology revealed two hemorrhagic cysts. The average duration of surgery was 231 minutes (range 92-391 minutes), and a mean blood loss of 930 mL (range 200-2500 mL) was recorded. Two operative dural tears and one postoperative wound dehiscence were observed. One patient had a recurrent synovial cyst at the site of original surgery Figure 13 displays dissection of the synovial cyst from the dura with decompression of the left lateral recess.

Ganglion cysts function much like synovial cysts but arise from the posterior longitudinal ligament (which is located behind the spine and inside the spinal canal). They often require surgical removal if they become symptomatic. The third kind of cyst is a Tarlov cyst, which is a cyst of the nerve roots commonly in the sacrum (or lower spine) The periarticular cyst is divided depending on the absence or presence of synovial epithelium on: ganglionic, synovial.

Synovial cysts can be easily overlooked. On these T2W-images it looks as if the foramen is normal. Notice that the nerve is missing. In fact the neuroforamen is almost completely filled by the synovial cyst, which compresses the nerve root against the vertebra (arrows). The nerve can hardly be seen In the lumbar spine, the spinal cord terminates into the cauda equina, a loose bundle of nerves. It occurs when pressure from a synovial cyst, disc herniation, or other pathology causes specific symptoms due to nerve compression. These symptoms affect the saddle and groin and include pain or numbness and tingling Synovial cysts are a rare cause of lumbar radiculopathy and back pain. Surgical treatment is directed at complete excision of the cyst. We used minimally invasive surgical techniques for a series. isal of their incidence and clinical significance. Although surgery is considered the treatment of choice, there is still no agreement over which surgical technique should be used. Methods: We retrospectively reviewed 23 consecutive patients undergoing surgery for a spinal synovial cyst in our department between 2004 and 2010. Surgical procedures were classified into the following 4 categories.

Surgical removal of the cyst is a safe and effective treatment for symptomatic relief in patients. The synovial cyst is a cyst or a fluid filled cavity. When the fluid escapes from the arthritic facet joint, because it is under pressure, it dilates the capsule of the facet joint and creates a cyst. The connection between the synovial cyst and the facet joint becomes obvious. The synovial cyst is walled off from the spinal canal

However, spinal fusion surgery clearly has superior results to non-fusion options. A precursor to degenerative spondylolisthesis is the development of facet cysts. These cysts emanate from the facet joints within the spinal column. There are two joints at each level of the spine. The cysts begin to develop as the spine becomes unstable ABSTRACT. A patient with posttraumatic lumbar radicular paresthesias is presented. The preoperative diagnosis of an epidural synovial cyst was considered. At surgery, an epidural synovial microcystic mass was found emanating from a distracted L4-5 facet joint and dissecting into the layers of the ligamentum flavum Intraspinal synovial cysts, sometimes referred to as ganglion cysts, are uncommon lesions which may present as acute or chronic low back pain, with or without radicular symptoms. We present two patients who presented with back pain and radicular symptoms attributable to the unusual pathology of an intraspinal synovial cyst An intraspinal lumbar synovial cyst can present with symptoms of nerve root compression. Given the presentation of lumbar-sacral radicular symptoms such as radiating pain, muscle weakness, and numbness, surgical excision of the lumbar synovial cyst remains the definitive treatment of choice

In order to identify this specific pathology in terms of pathogenesis, symptomatology and treatment, we reconsidered the ancient term of ganglion: Spinal ganglion cyst (SGC) may be the term of choice if the cyst originates from the articular process: The distinction between ganglion and synovial cyst is in fact purely histological Common examples include synovial cysts, ganglion cysts, and Tarlov cysts. Patients with these lesions can present with lumbar radiculopathy . Lumbar discal cyst (LDC) is a rare clinical entity with unknown etiology that has only been recently diagnosed.

This pattern consisted of mixtures of high signal intensity similar to that of fluid.

Methods. Two patient cases are described where the lumbar 4-5 facet cysts arise medial to the pedicle. Percutaneous access to the cysts was established by drilling through the adjacent pedicle creating a 7-mm corridor to establish access for the endoscopic tubular retractor and the working channel endoscope On histology the cyst showed signs of References chronic inflammation, as would be expected in an in- flammatory disease. 1.

Definition of synovial cysts: Synovial cysts are one of the most common pathologies of the wrist, they appear as swelling that is more or less round in shape (wrist ball).. The synovial cyst corresponds to a hernia of the wrist joint; the capsule and the synovial tissue form a membrane that holds the articular fluid inside the wrist joint.This membrane acts as a pouch that can fistulise out of. What is a synovial cyst? A synovial cyst is a relatively uncommon cause of spinal stenosis in the spine. It is a benign (non-cancerous) condition and the symptoms and level of pain and discomfort can remain stable for many years.

Synovial Cyst - an overview ScienceDirect Topic

The first description of a synovial cyst involving the spine was an autopsy study by Von Gruker 12). Epidemiology They are relatively rare, only 3 cases were identified in a series of 1500 spinal CT exams 13) but the frequency of diagnosis may be on the rise due to the widespread use of MRI and an increasing awareness of the condition Outcomes of surgical intervention for lumbar synovial cysts have been evaluated in the short and intermediate term. Concerns regarding cyst recurrence, the development of late instability at the involved level, and instability/stenosis at adjacent levels (when concomitant) fusion is performed suggest that long term follow-up is needed. This study aims to fill that void Similar & different: Ganglion cysts are swellings that often appear on jonts or tendons of the hands or feet. The fluid in ganglion cysts are thicker than in synovial cysts, often have multiple chambers and a fibrous lining. A synovial cyst is more likely to occur on an osteoarthritis joint, where there is leakage of fluid from the joint into the surrounding tissue

Spinal nerve root compression by synovial cysts was first reported by Vosschulte and Borger in 1950 5. The term juxtafacet cyst, which also encompasses ganglion cysts, was introduced by Kao et al. in 1974 6. Synovial cysts arise from the facet joint, most commonly at the L 4 -L 5 level 7, 8. Although the pathology is not completely. Histologically, a synovial cyst is a cavity lined by synovial cells oriented toward the lumen. Uncom­ plicated cysts have only fibrous tissue in the cyst wall outside of the synovial cells. Sheets of stromal and giant cells are not found.
