Abstract
OBJECTIVE Synovial cysts of the spine are rare lesions, predominantly arising in the lumbar region. Despite their generally benign behavior, they can cause severe symptoms due to compression of neural structures in the spinal canal. Treatment strategies are still a matter of discussion. The authors performed a single-center survey and literature search focusing on long-term results after minimally invasive surgery. METHODS A total of 141 consecutive patients treated for synovial cysts of the lumbar spine between 1997 and 2014 in the authors' department were analyzed. Medical reports with regard to signs and symptoms, operative findings, complications, and short-term outcome were reviewed. Assessment of long-term outcome was performed with a standardized telephone questionnaire based on the Oswestry Disability Index (ODI). Furthermore, patients were questioned about persisting pain, symptoms, and further operative procedures, if any. Subjective satisfaction was classified as excellent, good, fair, or poor based on the Macnab classification. RESULTS The approach most often used for synovial cyst treatment was partial hemilaminectomy in 70%; hemilaminectomy was necessary in 27%. At short-term follow-up, the presence of severe and moderate leg pain had decreased from 93% to 5%. The presence of low-back pain decreased from 90% to 5%. Rates of motor and sensory deficits were reduced from 40% to 14% and from 45% to 6%, respectively. The follow-up rate was 58%, and the mean follow-up period was 9.3 years. Both leg pain and low-back pain were still absent in 78%. Outcome based on the Macnab classification was excellent in 80%, good in 14%, fair in 1%, and poor in 5%. According to the ODI, 78% of patients had no or only minimal disability, 16% had moderate disability, and 6% had severe disability at the time of follow-up. In this cohort, 7% needed surgery due to cyst recurrence, and 9% required a delayed stabilization procedure after the initial operation. CONCLUSIONS Surgical treatment with resection of the cyst provides favorable results in outcome. Excellent or good outcome persisting for a long-term follow-up period can be achieved in the vast majority of cases. Complication rates are low despite an increased risk of dural injury. With facet-sparing techniques, the stability of the segment can be preserved, and resection of spinal synovial cysts does not necessarily require segmental fusion.

Abstract
Typically situated posterolateral in the spinal canal, intraspinal facet cysts often cause radicular symptoms. Rarely, the midline location of these synovial or ganglion cysts may cause thecal sac compression leading to neurogenic claudication or cauda equina syndrome. This article summarizes the clinical presentation, radiographic appearance, and management of three intraspinal, midline facet cysts. Three patients with symptomatic midline intraspinal facet cysts were retrospectively reviewed. Documented clinical visits, operative notes, histopathology reports, and imaging findings were investigated for each patient. One patient presented with neurogenic claudication while two patients developed partial, subacute cauda equina syndrome. All 3 patients initially responded favorably to lumbar decompression and midline cyst resection; however, one patient required surgical stabilization 8 mo later. Following the three case presentations, we performed a thorough literature search in order to identify articles describing intraspinal cystic lesions in lateral or midline locations. Midline intraspinal facet cysts represent an uncommon cause of lumbar stenosis and thecal sac compression. Such entities should enter the differential diagnosis of midline posterior cystic lesions. Midline cysts causing thecal sac compression respond favorably to lumbar surgical decompression and cyst resection. Though laminectomy is a commonly performed operation, stabilization may be required in cases of spondylolisthesis or instability.

Abstract
PURPOSE Primary intraspinal facet cysts in the lumbar spine are uncommon, but it is unclear whether cyst incidence increases following decompression surgery and if these cysts negatively impact clinical outcome. We examined the prevalence, clinical characteristics, and the risk factors associated with intraspinal facet cysts after microsurgical bilateral decompression via a unilateral approach (MBDU). METHODS We studied 230 patients treated using MBDU for lumbar degenerative disease (133 men and 97 women; mean age 70.3 years). Clinical status, as assessed by the Japanese Orthopedic Association (JOA) score and findings on X-ray and magnetic resonance images, was evaluated prior to surgery and at both 3 months and 1 year after surgery. The prevalence of intraspinal facet cysts was determined and preoperative risk factors were defined by comparing presurgical findings with clinical outcomes. RESULTS Thirty-eight patients (16.5%) developed intraspinal facet cysts within 1 year postoperatively, and 24 exhibited cysts within 3 months. In 10 patients, the cysts resolved spontaneously 1 year postoperatively. In total, 28 patients (12.2%) had facet cysts 1 year postoperatively. The mean JOA score of patients with cysts 1 year postoperatively was significantly lower than that of patients without cysts. This poor clinical outcome resulted from low back pain that was not improved by conservative treatment. Most cases with spontaneous cyst disappearance were symptom-free 1 year later. The preoperative risk factors for postoperative intraspinal facet cyst formation were instability (OR 2.47, P = 0.26), scoliotic disc wedging (OR 2.23, P = 0.048), and sagittal imbalance (OR 2.22, P = 0.045). CONCLUSIONS Postoperative intraspinal facet cyst formation is a common cause of poor clinical outcome in patients treated using MBDU.

Abstract
Lumbar spine synovial cysts are becoming more frequent, and they are generally associated with degenerative lumbar spinal disease. They are common in lower lumbar lesions but rare in upper lumbar lesions. Several cases of hemorrhage into lower lumbar juxtafacet cysts after trauma or anticoagulation therapy have been reported in the literature. This article describes a case of subacute cauda equina syndrome resulting from spontaneous hemorrhage into an upper lumbar synovial cyst. A 65-year-old man presented with a 3-month history of intermittent bilateral lumbar pain. One week before, he experienced a sudden exacerbation of lumbar pain and began falling frequently; he also reported weakness and tingling in his lower limbs. A hematic collection associated with a large juxtafacet cyst at L2-L3 was suspected on magnetic resonance imaging. He underwent surgical decompression, and the cyst was resected. Microscopic examination was consistent with the diagnosis of a synovial cyst. Two days postoperatively, he was walking independently. Although several descriptions exist of hemorrhagic lumbar juxtafacet cysts after trauma or anticoagulant therapy, to the authors' knowledge, this is the first documented case of hemorrhage in an upper lumbar synovial cyst with no previous traumatic event or medication use. Magnetic resonance imaging was essential in making the preoperative diagnosis. Surgical removal of the cyst was an effective treatment.

Abstract
BACKGROUND AND IMPORTANCE Intraspinal synovial cysts are uncommon causes of back and radicular leg pain. Usually associated with degenerative spinal disease, these juxtafacet cysts are usually located in the lumbar spine and may rarely undergo intracystic hemorrhage. The pathogenesis of these cysts are unclear, and risk factors that may contribute to hemorrhagic complications are largely unknown. CLINICAL PRESENTATION A 68-year-old man presented to the clinic 4 months after a fall on ice with persistent back pain and lumbar radiculopathy. A week after the initial clinic consultation, the patient presented to the emergency room with increased pain and worsening weakness in the left foot. An emergent magnetic resonance image showed thecal sac compression secondary to a large, juxtafacet cyst that was hyperintense on T1-weighted and hypointense on T2-weighted images. Lumbar decompressive laminectomies were performed at L3 and L4 with cyst removal and stabilization. CONCLUSION We present the eighth reported case of a hemorrhagic juxtafacet cyst secondary to physical trauma, the second in which the patient's symptoms acutely worsened several months after the initial insult without new trauma. We also present summary statistics of the 31 cases of hemorrhagic juxtafacet cysts reported in the literature and propose a putative mechanism that may account for the development and progression of symptoms in some patients.

Abstract
BACKGROUND CONTEXT With improvements in neurological imaging, there are increasing reports of symptomatic spinal synovial cysts. Surgical excision has been recognized as the definitive treatment for symptomatic juxtafacet cysts. However, the role for concomitant fusion and the incidence of recurrent back pain and recurrent cyst formation after surgery remain unclear. PURPOSE To determine the cumulative incidence of postoperative symptomatic relief, recurrent back and leg pain after cyst resection and decompression, and synovial cyst recurrence. STUDY DESIGN Systematic review of the literature. PATIENT SAMPLE All published studies to date reporting outcomes of synovial cyst excision with and without spinal fusion. OUTCOME MEASURES Cyst recurrence and Kawabata, Macnab, Prolo, or Stauffer pain scales. METHODS We performed a systematic literature review of all articles published between 1970 and 2009 reporting outcomes after surgical management of spinal synovial cysts. RESULTS Eighty-two published studies encompassing 966 patients were identified and reviewed. Six hundred seventy-two (69.6%) patients presented with radicular pain and 467 (48.3%) with back pain. The most commonly involved spinal level was L4-L5 (75.4%), with only 25 (2.6%) and 12 (1.2%) reported synovial cysts in the cervical or thoracic area, respectively. Eight hundred eleven (84.0%) patients were treated with decompressive surgical excision alone, whereas 155 (16.0%) received additional concomitant spinal fusion. Six hundred fifty-four (92.5%) and 880 (91.1%) patients experienced complete resolution of their back or leg pain after surgery, respectively. By a mean follow-up of 25.4 months, back and leg pain recurred in 155 (21.9%) and 123 (12.7%) patients, respectively. Sixty (6.2%) patients required reoperation, of which the majority (n=47) required fusion for correction of spinal instability and mechanical back pain. Same-level synovial cyst recurrence occurred in 17 (1.8%) patients after decompression alone but has been reported in no (0%) patients after decompression and fusion. CONCLUSIONS Surgical decompression results in symptomatic resolution in the vast majority of patients; however, recurrent back pain occurs in a significant number of patients. Cyst recurrence occurs in less than 2% of patients but has never been reported after cyst excision with concomitant fusion. The lack of cyst recurrence after concomitant fusion supports the need to investigate the value of fusion of the involved motion segment in the treatment of symptomatic synovial cysts of the spine.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE Compare outcomes of different treatment methods for intraspinal synovial cysts. SUMMARY OF BACKGROUND DATA Intraspinal synovial cysts are cited as an increasing cause of back pain and radiculopathy. To date, few studies have compared outcomes of differing treatment methods in patients with synovial cysts. METHODS We retrospectively reviewed 167 consecutive patients undergoing surgical management of 195 symptomatic synovial cysts at a single institution over 19 years. The incidence of postoperative mechanical back pain, radiculopathy, and cyst recurrence was compared between patients undergoing unilateral hemilaminectomy (n = 51), bilateral laminectomy (n = 39), facetectomy with in situ fusion (n = 18), and facetectomy with instrumented fusion (n = 56). RESULTS A total of 155 (97.5%) patients presented with radiculopathy, 132(82.5%) with mechanical back pain, 31 (20%) with neurogenic claudication, and 5 (3.2%) with bladder dysfunction. Most cysts occurred in the lumbar spine. After surgery, back and radicular pain improved in 91.6% and 91.9% patients, respectively. By a mean follow-up of 16 +/- 9 months, 36 (21.6%) patients developed recurrent back pain, 20 (11.8%) recurrent leg pain, and 5 (3%) recurrent synovial cysts. Patients undergoing laminectomy had a significantly increased cyst recurrence incidence compared to fusion groups via log-rank test (P = 0.042), and this risk was decreased to baseline with instrumented fusion on reoperation. Laminectomy was also associated with the highest increased risk of recurrent back pain in both log-rank test (P = 0.018) and proportional hazards regression (HR): 1.64 (1.00-3.45), P = 0.05. Instrumented fusion had the lowest risk for back pain recurrence. CONCLUSION Hemilaminectomy or laminectomy remains one of the mainstay surgical treatments for symptomatic intraspinal synovial cysts. Our experience shows that the majority of patients undergoing decompression/excision of synovial cysts will have immediate improvement in back and leg pain. However, within 2 years, patients receiving hemilaminectomy or laminectomy alone have an increased incidence of back pain and cyst recurrence. Decompression with instrumented fusion appears to be associated with the lowest incidences of cyst recurrence or back pain.

Abstract
We present 4 cases of facet cyst haematoma in the ligamentum flavum of the lumbar spine. All patients presented with a one-to-3-month history of back pain or numbness in the legs, and sudden neurological deterioration. One also developed cauda equina syndrome and another developed radiculopathy. In all cases, magnetic resonance imaging showed a mass with high signal intensity on both T1- and T2-weighted images. Facet arthrography and computed tomography revealed communication between the mass and the neighbouring facet joint. The haematomas were removed en bloc with the ligamentum flavum. They were surrounded by the ligament and contained degenerated and lacerated elastic fibres but no synovial lining cells. Facet cyst haematoma is so-named because of bleeding from tissue adjacent to the facet joint into a pre-existing facet cyst.

Abstract
STUDY DESIGN Case report. OBJECTIVE To describe a case of a subacute radiculopathy resulting from a spontaneous hemorrhage into a lumbar ganglion cyst. SUMMARY OF BACKGROUND DATA Ganglion and synovial cysts of the lumbar spine are becoming more frequent, and they are generally associated with degenerative lumbar spinal disease. Few cases of hemorrhage into lumbar juxtafacet cysts after trauma or anticoagulation therapy have been described in the literature. METHODS A case of a spontaneous hemorrhage in a lumbar ganglion cyst is presented. RESULTS A 61-year-old man presented with a 2-month history of intermittent bilateral lumbar ache. Eight days before admission he had a sudden exacerbation of the lumbar pain and began to fall frequently and noticed weakness and tingling in his lower members, mainly in the right leg. Magnetic resonance imaging scan revealed a hematic collection associated with a large juxtafacet cyst at the L4-L5 level. He was submitted to surgery and the cyst was totally removed. Microscopic examination was consistent with the diagnosis of a ganglion cyst. Two days after surgery he had already an independent gait. CONCLUSION Although, there are a few descriptions of hemorrhagic lumbar justafacet cysts after trauma or anticoagulant therapy, this is the first case of a hemorrhagic ganglion cyst with no previous traumatic event or use of medication. Magnetic resonance imaging was essential for making the preoperative diagnosis. Neurosurgical cyst removal proved to be an effective treatment.

Abstract
STUDY DESIGN Case report. OBJECTIVE To describe a case of spinal epidural hematoma arising from the synovial joint due to anticoagulation therapy. SUMMARY OF BACKGROUND DATA Spontaneous spinal epidural hematoma is a rarity in the literature with a variety of etiologies. In 1 study, it was reported to originate from a synovial joint due to osteoarthritis of the joint. METHODS A case of hematoma of the lumber synovial joint is presented. RESULTS A 67-year-old man who was on anticoagulation therapy presented with progressive neurologic symptoms in the right lower limb. Magnetic resonance imaging scan revealed what was thought to be a L4-L5 synovial joint cyst. During surgery, it was proven to be an epidural hematoma originating from the synovial joint. Microscopic examination confirmed the diagnosis and excluded the possibility of spinal synovial cyst. After spinal decompression, neurologic symptoms improved completely in 2 weeks. CONCLUSIONS This is the first report of a synovial cyst hematoma due to anticoagulation therapy. Its magnetic resonance imaging features can be similar to synovial cyst, especially when it is hemorrhagic. Spinal decompression was the definitive treatment.

Abstract
We report the case of a hemorrhagic lumbar juxta facet cyst (L2-L3), revealed by a chronic right lumbocruralgia, in a 77-year-old woman treated by anticoagulants for cardiac arrhythmia. Computerized tomography and magnetic resonance imaging suggested the diagnosis of benign tumor. During surgical removal of the whole lesion, a hemorrhagic synovial cyst was evoked. The operation dramatically relieved the symptoms. The diagnosis was confirmed by the histopathological analysis confronted with the clinical and the radiological findings. This uncommon observation allows the discussion of the pathogenic mechanism and of the differential diagnosis.

Abstract
BACKGROUND To define the etiologic, clinical, histological, and surgical features of lumbar hemorrhagic synovial cysts (LHSCs). Three personal cases are reported together with a review of the pertinent literature. METHODS We identified 3 cases of LHSC treated in our departments and 20 cases culled from the literature. RESULTS A total of 23 cases of LHSC were selected. All the patients underwent surgical treatment because of untreatable radicular pain and/or neurological deficits. The amount of bleeding, either massive or minor but repeated, influenced the timing of surgery. In our cases, the histological examinations showed an inflammatory reaction within the cyst and the consequent formation of neoangiogenic vessels. CONCLUSIONS Hemorrhagic synovial cyst of the spine is rare and its most common localization is lumbar. Bleeding within the cyst leads to an increase of its volume, accompanied by neurological deficits and/or painful symptoms that are violent and generally intractable. In this event, surgical excision is the treatment of choice and, in some cases, emergency surgery is necessary. Hemorrhages are probably caused by the rupture of fragile neoangiogenic vessels.

Abstract
OBJECTIVE The majority of lumbar facet joint cysts (LFJCs) are located in the spinal canal, on the medial aspect of the facet joint with characteristic diagnostic features. When they migrate away from the joint of origin, they cause diagnostic problems. MATERIALS AND METHODS In a 7-year period we examined by computed tomography (CT) and magnetic resonance (MR) imaging five unusual cases of facet joint cysts which migrated from the facet joint of origin. RESULTS Three LFJCs were identified in the right S1 foramen, one in the right L5-S1 neural foramen and one in the left erector spinae and multifidus muscles between the levels of L2-L4 spinous process. CONCLUSIONS Awareness that spinal lesions identified at MRI and CT could be due to migrating facet joint cyst requires a high level of suspicion. The identification of the appositional contact of the cyst and the facet joint needs to be actively sought in the presence of degenerative facet joints.

Abstract
BACKGROUND CONTEXT Acute onset of radicular symptoms has been reported following hemorrhage into lumbar synovial cysts after trauma or in cases of spinal instability. No previous cases have been linked to anticoagulation therapy. PURPOSE To present a case of symptomatic hemorrhagic lumbar synovial cyst occurring after anticoagulation therapy. STUDY DESIGN A case report and review of the literature. METHODS A patient presented with low back and radicular pain secondary to a large synovial facet cyst. Magnetic resonance imaging revealed a large facet cyst compressing the thecal sac and L3 exiting nerve root. RESULTS The synovial cyst was excised during a lumbar decompression and fusion. Gross blood was present in the cyst. CONCLUSIONS This is the first reported case of symptomatic hemorrhagic lumbar facet cyst associated with anticoagulation therapy.

Abstract
Facet joint cysts are commonest at the L4-L5 level and are associated with facet joint degeneration and type III (degenerative) spondylolisthesis. It is extremely rare for facet joint cysts to cause symptomatic cauda equina compression. Three elderly patients presented to us with significant cauda equina compression caused by facet joint cysts. One presented with classic symptoms and signs of a cauda equina syndrome, a second with bilateral lower limb neurologic loss associated with uncontrolled epilepsy, and the third with bilateral leg symptoms as well as an upper limb tremor and fasciculation. The diagnosis was easily made after magnetic resonance scanning in two patients, although in one patient, it was significantly delayed because of his confounding neurologic picture. Lumbar spine surgery (decompression and cyst resection) was successful in resolving symptoms in all three, even though two patients had significant neurologic compromise before surgery. The occurrence of facet joint cysts in older patients can be associated with other degenerative neurologic conditions, and the diagnosis might not be apparent early. We suggest that in older patients who have a mixed picture of central and peripheral neurologic compromise, this diagnosis should be considered and investigation of the whole of the spine, not just the brain and spinal cord, should be undertaken.

Abstract
OBJECT Thoracic synovial cysts (TSCs) are rare and are usually the subject of case reports. The authors studied the clinical manifestations, radiological aspects, and surgical treatment in a series of patients at their institution who harbored TSCs. They also review the literature to discuss the potential factors involved in the pathogenesis of this lesion. METHODS A database search of 16,000 patients who underwent decompressive spine surgery at the Mayo Clinic (Rochester, MN) between 1976 and 2003 disclosed nine patients (0.06%) in whom a diagnosis of TSC had been made. All patients were men. The mean age at presentation was 73 +/- 5 years and mean duration of symptoms was 5 +/- 3 months. The mean duration of follow up was 4 +/- 3 years. The patients had no history of trauma or spine surgery. All patients had spastic paraparesis; two had urinary difficulties. Detailed neurological examination revealed myelopathy and radiculopathy with a sensory level of T10-L4. Magnetic resonance imaging revealed bilateral cysts in four patients and unilateral lesions in five. Three of the cysts were at the T-10 interspace, seven at the T-11 interspace, and three at the T-12 interspace. Seven cysts were on the right and six were on the left. Computerized tomography myelography performed in five patients revealed a gas bubble in the TSC in two patients. All patients underwent laminectomy/partial facetectomy, excision of the cyst, and decompression of the thecal sac and nerve root without any complications. None of these patients underwent a fusion. Eight patients (89%) experienced moderate to excellent relief of their preoperative signs and symptoms and one patient (11%) remained stable. There was no evidence of cyst recurrence at the site of surgery or other spinal segments at follow-up examination in any patient. CONCLUSIONS When compared with their lumbar and cervical spine counterparts, TSCs are exceedingly rare. Their rarity may be explained by the decreased mobility of the thoracic spinal segments. The origin of TSCs is more likely degenerative rather than traumatic. Based on their experience and the follow-up duration, surgery provided durable relief from symptoms.

Abstract
Synovial cysts have been well reported as a cause of sciatica, with a sudden acute exacerbation being attributed to haemorrhage and subsequent enlargement of the cyst. Cyst formation is attributed to facet joint degeneration associated with a defect or rupture of the joint capsule. The mechanisms of haemorrhage have not been well described previously. Two cases of haemorrhagic synovial cysts causing acute exacerbation of sciatica are described. Both cases were directly attributable to manipulation of degenerate spines. The MRI and histopathological findings are discussed and we propose a mechanism whereby excessive stress on a degenerate revascularized synovium leads to haemorrhage within synovial cysts.

Abstract
BACKGROUND CONTEXT Lumbar intraspinal synovial cysts are an important cause of axial and radicular spine pain. Controversy about nonsurgical versus surgical treatment persists. PURPOSE To evaluate the efficacy of nonsurgical management of symptomatic lumbar intraspinal synovial cysts (LISCs). STUDY DESIGN/SETTING Retrospective review set in outpatient physiatry office. PATIENT SAMPLE Ten patients (8 women, 2 men; average age, 60 years) with LISCs and average symptom duration of 7.9 months. OUTCOME MEASURES Numerical pain rating scale (NRS-11), Roland-Morris disability outcome measure, patient satisfaction, and surgery. METHODS Patients with LISCs were identified and their charts were reviewed. Those patients whose symptoms correlated with the level of LISC-induced extradural compression were eligible. All patients received conservative care and a fluoroscopic-guided lumbar spine injection. The primary author conducted telephone follow-up. RESULTS All 10 patients had unilateral radicular pain. Seven had stable neurologic deficits. Magnetic resonance imaging and computed tomography/myelography, respectively, identified a LISC in 8 and 2 patients. Five patients had cyst aspiration followed by steroid instillation; 5 patients had cyst aspiration followed by a transforaminal epidural steroid injection. Average length of follow-up was 50.4 weeks. Only 1 patient had sustained benefit. One patient had no benefit and refused surgery. Eight patients underwent surgery and had a good result. CONCLUSION In our opinion, nonsurgical management in patients with LISC-induced radicular pain does not appear to be as successful as surgery.

Abstract
Synovial cysts emanating from the lumbar facet joints may compromise the spinal canal and produce symptoms of radiculopathy or stenosis. Good results have been reported after excision of the symptomatic lesions. There are limited data, however, on the natural history involving nonoperative management and little information to suggest that these lesions ever regress spontaneously. The authors report on three patients in whom symptomatic lumbar synovial cysts spontaneously resolved and review the relevant literature.

Abstract
STUDY DESIGN A case is reported in which a 45-year-old man developed cauda equina syndrome caused by enlargement of an L4-L5 juxtafacet cyst diagnosed 4 months earlier. OBJECTIVES To highlight the short interval that can elapse between the discovery of a juxtafacet cyst and its remarkable progression. SUMMARY OF BACKGROUND DATA Although juxtafacet cysts are acquired lesions, how long they take to develop remains unclear. Hemorrhage is a well-known cause of rapid or even dramatic cyst enlargement. This is the first report providing magnetic resonance imaging evidence of rapid, remarkable enlargement of a nonhemorrhagic juxtafacet cyst. METHODS The patient underwent conservative treatment for an L4-L5 right juxtafacet cyst diagnosed by magnetic resonance imaging during evaluation of posttraumatic lower back pain. Four months later, the patient presented with severe pain radiating down the right lateral leg, urinary retention, and impaired dorsal flexion of the right foot. Repeat magnetic resonance imaging showed the cyst now markedly enlarged and occupying almost the entire width of the canal. RESULTS The cyst was removed, and the patient's symptoms abated. At 15 months after surgery, he is symptom-free. CONCLUSIONS Juxtafacet cyst may occasionally enlarge and cause severe symptoms within months.

Abstract
PURPOSE To determine the imaging characteristics of lumbar facet joint synovial cysts after percutaneous treatment with steroid injections and distention of the cyst and to correlate these findings with the clinical outcome. MATERIALS AND METHODS Clinical outcome and imaging findings were retrospectively studied in 12 patients (four men, eight women) aged 45-79 years (mean, 60 years) with a symptomatic lumbar facet joint synovial cyst treated with percutaneous steroid injections. At varying times after the procedure, patients were contacted for clinical follow-up, and repeat imaging was performed to verify the status of the cyst. RESULTS Excellent pain relief was achieved in nine (75%) of 12 patients. At follow-up imaging, the cyst completely regressed in six (67%) of these nine patients, partially regressed in two (22%) patients, and was unchanged in one (11%) patient. One (8%) of the 12 patients had transient pain relief, with recurrence of symptoms at short intervals after each of three injections. No pain relief was achieved in two (17%) of 12 patients. CONCLUSION Image-guided percutaneous steroid injections are often effective in the treatment of lumbar facet joint synovial cysts and may result in complete regression of the cyst.

Abstract
STUDY DESIGN Retrospective review of patients who underwent lumbar juxtafacet cyst resection with questionnaire follow-up. OBJECTIVES Determine the long-term outcome after resection of lumbar juxtafacet cysts. SUMMARY OF BACKGROUND DATA Juxtafacet cysts are uncommon causes of radicular pain and are often associated with significant spinal degenerative disease. Previous studies have not focused on the outcome of patients who have undergone resection. METHODS Charts of 29 patients who underwent lumbar juxtafacet resection were reviewed and an outcomes questionnaire was sent to each. RESULTS Thirty-three lumbar juxtafacet cysts were resected from 29 patients. Cysts, 31 (94%) from facets and 2 (6%) from the ligamentum flavum, most commonly arose at the L4-L5 level (51%). Twelve patients (41%) were found to have some degree of spondylolisthesis before surgery, while 26 patients (90%) had facet arthropathy. Two patients (7%) underwent concurrent resection and fusion. Recurrence occurred in 3%. Three patients (9%) had subsequent lumbar spine operations, including 2 fusions (6%). Incidental durotomy was the most common surgical complication occurring in 3 cases (9%). Twenty-four patients (83%) responded to follow-up questionnaire or phone interview. Mean length of follow-up was 24 months (4-64 months). Twenty patients (83%) reported improvement in pain, and 16 (67%) reported an improved level of function. All respondents reported some degree of improvement in their condition after surgery. CONCLUSIONS Juxtafacet cysts are an uncommon cause of radiculopathy. Surgical resection is the treatment of choice with low rates of complications, recurrences, and residual complaints.

Abstract
OBJECT The authors report a retrospective analysis of 194 patients surgically treated at their institutions for symptomatic lumbar synovial cysts from January 1974 to January 1996. METHODS Patient characteristics including age, sex, symptoms, signs, and preoperative neuroimaging studies were reviewed. Surgical procedures, complications, results, and pathological findings were correlated with preoperative assessment. One hundred ninety-four patients were surgically treated for symptomatic lumbar synovial cysts. Eighty percent were diagnosed and treated between 1987 and 1996. There were 100 men and 94 women with an average age of 66 years (range 28-94 years). The most common symptoms were painful radiculopathy (85%) and neurogenic single or multiroot claudication (44%). However, sensory loss (43%) and motor weakness (27%) were also presenting symptoms. Eleven percent of patients had undergone previous lumbar surgery prior to being referred to the Mayo Clinic. Preoperative neurological examination demonstrated motor weakness (40%), sensory loss (45%), reflex changes (57%), and variants of cauda equina syndrome (13%). In 19% of patients, normal neurological status was demonstrated. There was equal left/right-sided laterality, and eight patients presented with bilateral synovial cysts. The most commonly affected level was L4-5 (64%). All patients underwent laminectomy and resection of the cyst. Concomitant fusion was performed in 18 patients in whom clinical evidence of instability had been observed. However, subsequent fusion was required in only four patients who developed symptomatic spondylolisthesis. Surgery-related complications included cerebrospinal fluid leak (three patients), discitis (one patient), epidural hematoma (one patient), seroma (one patient), and deep vein thrombosis (one patient). One patient died 3 days after surgery of cardiac dysrhythmia. Follow-up data obtained for at least 6 months postoperatively were available in 147 patients. Of these, 134 (91%) reported good relief of their pain and 82% experienced improvement in their motor deficits. CONCLUSIONS Lumbar synovial cysts are a more common cause of lumbar radicular pain than previously thought. Surgical removal of the cyst is a safe and effective treatment for symptomatic relief in patients with lumbar synovial cysts. A concomitant fusion procedure may be performed in select cases. In this study, only a few patients developed symptomatic spinal instability requiring a second operation.
