[Ab] Abstract:AIMS: Cystic lesions derived from the synovial and ligamentous structures of the spine have varied histological appearances. Not uncommonly, there is discrepancy between the clinicoradiological diagnosis and histology. Therefore, we sought to characterise the histological features of tissue submitted as 'synovial cysts' of the spine. METHODS AND RESULTS: Resected specimens of the spine labelled 'synovial cysts' and 'lumbar cysts' were histologically evaluated and classified on the basis of histopathological features. Seventy-five histological samples of spinal cysts were identified. Thirty-one were classified as synovial cysts (definite synovial lining), 28 showed pseudocystic degeneration of the ligamentum flavum, seven showed pseudocyst formation without evidence of a synovial lining or degeneration of the ligamentum flavum, and eight showed cyst contents only or no histological evidence of cyst wall for evaluation. Twenty-five cases (33%), especially those showing pseudocystic degeneration of the ligamentum flavum, were associated with very characteristic tumour calcinosis-like calcium deposition with a surrounding foreign-body giant-cell reaction. 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. This may have implications not only for understanding the pathogenesis of these lesions, but also for their varied responses to non-surgical interventions.

[Ab] Abstract:To classify facet joint cysts (FJC) which will assist in identification of patient groups to best fit with a particular intervention. Sagittal T -weighted magnetic resonance images (MRI) of these patients are used to measure cyst size, while axial T -weighted MRI are used to determine the percentage of the vertebral canal occupied by the cyst. The degree of spondylolisthesis is also measured through standing X-rays or sagittal MRI. The proposed grading system is as follows. Grade I includes cysts that occupy less than 25% of the canal diameter that usually present with unilateral radiculopathy. Grade II includes cysts that occupy less than 50% of the canal diameter and may present with radiculopathy, with or without claudicant symptoms. Grade III cysts may present with radiculopathy and claudication with bilateral leg symptoms, along with facetogenic pain symptoms. Grades IV and V include potential instability as defined by greater than 15% spondylolisthesis in addition to either less than or greater than 50% canal stenosis. With higher grade cysts, presentation may include: facetogenic back pain, radiculopathy and claudicant pain in variable degrees of severity. The optimal classification system grades FJC from I to V on the basis of canal compression and degree of spondylolisthesis. Prospective studies are required to confirm the validity of this grading scale for long-term use.

[Ab] Abstract:RATIONALE: Synovial cysts are well known in rheumatoid arthritis (RA), and most common in the popliteal fossa. They may produce lots of local symptoms and complaints, which may present initially as an unrelated clinical condition. Few studies have reported multiple extra-articular synovial cysts (MESCs) in the RA patients. Early diagnosis is crucial for patient treatment. PATIENT CONCERNS: A 50-year-old man without any special clinical histories found a soya bean size bump at the left elbow medially, then multiple lumps were found at bilateral elbows and gradually increasing. No pain, no activity, no redness, and swelling. Magnetic resonance imaging (MRI) showed multiple cystic lesions in the bursa and surrounding soft tissue of bilateral elbow joints. In addition, the elbow joint bursa was swollen and the synovial membrane was significantly thickened. DIAGNOSES: The man was diagnosed as RA with multiple extra-articular synovial cysts formation. INTERVENTIONS: The patient was performed tylectomy of the right elbow. Other lumps were punctured and injected with compound betamethasone injection. OUTCOMES: The bumps were reduced in size and the swelling relieved, and the patient was sent to the department of rheumatology and immunology for further treatment. LESSONS: In this case, it is difficult for the diagnosis of RA because of no relative histories and simultaneously multiple cystic lesions in multiple joints. Imaging examinations can show the characteristics of such kind of disease and be very helpful for the diagnosis and differentiate diagnosis.

[Ab] Abstract:CASE: A 25-year-old man with synovial chondromatosis of the hip was treated with a synovectomy through a transtrochanteric approach; the repair was made with use of a Dall-Miles cable. Approximately 13 years later, the patient returned with a massive bursal reaction and a cyst containing "rice bodies." Although the physical examination and imaging were suggestive of recurrent synovial chondromatosis, the bursal reaction actually represented a novel complication of the Dall-Miles system. CONCLUSION: When a patient who has had prior orthopaedic instrumentation presents with pain and imaging that demonstrates formation of a bursal cyst, a cyst containing rice bodies secondary to bursal irritation by the implant should be considered.

[Ab] Abstract:CASE: We report a rare case of a dorsal synovial ganglion of the left hip causing L5 radiculopathy in a 48-year-old woman. After a 12-month history of intermittent pain in the groin, left buttock, and left lower limb, magnetic resonance imaging (MRI) of the pelvis revealed a 10-cm-long cystic ganglion. The lesion originated from the posterior aspect of the hip joint capsule and extended through the sciatic notch toward the L5 nerve root, causing severe nerve compression. Open resection of the ganglion via surgical hip subluxation was performed. CONCLUSION: Combined presentation of symptoms attributable to intrinsic hip disease and peripheral radiculopathy should raise suspicion for a shared cause of these entities.

[Ab] Abstract:BACKGROUND: Ligamentum flavum cysts are thought to develop due to facet joint hypermobility; however, the etiology of these lesions is not completely elucidated. These cysts may lead to compressive pathologies of the spine requiring surgical intervention. CASE REPORT: We report the case of a 63-year-old male with chronic back pain and progressive neurogenic claudication for 6 months. He was found to have a ligamentum flavum cyst situated along the dorsal midline of the lumbar spinal canal contributing to spinal stenosis. The patient underwent a decompressive L4 laminectomy and en bloc excision of the ligamentum flavum cyst with complete resolution of his symptoms postoperatively. CONCLUSIONS: We suggest that chronic mechanical stress leads to degeneration of the ligamentum flavum and contributes directly to cyst formation.

[Ab] Abstract:CLINICAL ISSUE: Spinal cysts can be classified as meningeal, not meningeal, and tumor-associated cysts. Due to the widespread availability of high-resolution computed tomography and magnet resonance imaging, spinal cysts can be detected with high sensitivity these days. Concerning the variety of potential cystic differential diagnoses, a precise classification is difficult and can often only be realized after surgical inspection or histological examination. PRACTICAL RECOMMENDATIONS: Spinal cysts are generally incidental findings during a routine diagnostic workup and need no further therapy. Surgical treatment can be necessary if the spinal cyst reaches a certain size and causes neurological symptoms due to the compression of the spinal cord or the nerve root.

[Ab] Abstract:The intraoperative use of intravenous fluorescein is presented in a case of peroneal intraneural ganglion cyst. When illuminated with the operative microscope and yellow filter, this fluorophore provided excellent visualization of the abnormal cystic peroneal nerve and its articular branch connection. The articular (synovial) theory for the pathogenesis of intraneural cysts is further supported by this pattern of fluorescence. Further, our report presents a novel use of fluorescein in peripheral nerve surgery.

[Ab] Abstract:BACKGROUND: Synovial cysts of the hip are relatively rare lesions comparing to other joints. Patients are usually asymptomatic, but in some cases symptoms such as pain and/or compression of vessels or nerve could be present. Purpose of the study was to define clinical features and optimal management of synovial cyst of the hip joint through an accurate review of the literature. METHODS: We present three consecutive cases treated with three different therapeutic strategies: surgical excision, wait-and-see and needle aspiration. An accurate review of the literature has been performed to identify patients who had been treated for synovial cyst of the hip. RESULTS: Due to the rarity of the disease, there are no significant data in literature supporting the gold standard of treatment. Treatment of the synovial cyst depends on their size, symptoms and comorbidities. CONCLUSIONS: Most of the Authors recommend surgical treatment for symptomatic synovial cysts and needle aspiration as an option treatment in asymptomatic patients without vessel or nerve compression. In patients that referred symptoms in correspondence with the hip joint, not strictly related with radiograph findings, a CT or MRI examinations should be performed to exclude possible differential diagnosis.

[Ab] Abstract:OBJECTIVE: To investigate the clinical curative effects of internal drainage by expanding arthroscopic gastrocnemius-semimembranosus bursa(GSB) and cyst wall resection for the treatment of popliteal cysts. METHODS: A retrospective analysis of patients from May 2011 to December 2015. Arthroscopic treatment for 41 patients with popliteal fossa cysts, 18 males and 23 females, aged from 34 to 67 years old, averaged 42.6 years old. All the patients had preoperative magnetic resonance imagings to confirm the diagnosis and identify the valvular opening(Gastrocnemius-Semimembranosus bursa, GSB), as well as the associated intra-articular pathology. All the popliteal cysts were unilateral, including 26 cases of right knees and 15 cases of left knees. Five patients had recurrent popliteal cysts, and all of them underwent initial open Surgery. The duration from initial surgery to the recurrence ranged from 6 to 17 months(averaged, 11 months). All the patients had underwent arthroscopic treatment of internal drainage by expanding GSB and cyst wall resection. According to the Rauschning and Lindgren classification, 5 cases were grade I , 30 cases were grade II and 6 cases were grade III. Preoperative Lysholm score, 83.19±6.12 (ranged form 73 to 95). RESULTS: The GSB structure was found in all patients with popliteal cysts during operation, including cartilage degeneration in 33 cases, medial meniscus injury in 27 cases, lateral meniscus injury in 7 cases, free body in 8 cases, pigmented villonodular synovitis in 2 cases, and synovial chondromatosis in 3 cases. There were no complications related to vascular, nerve or surgical incision. All the patients were followed up, and the duration ranged from 8 to 27 months, with an average of 18 months. No recurrence of cysts was found. According to the Rauschning and Lindgren classification, there were 9 cases of grade 0, 27 cases of grade I , 4 cases of grade II, 1 case of grade III. Postoperative Lysholm score:91.32±4.26(ranged from 82 to 98). CONCLUSIONS: Arthroscopic internal drainage by expanding GSB and cyst wall resection surgery in the treatment of popliteal cysts has the advantages of less trauma, faster recovery and low relapse rate, which has a good short-term effect.
