Abstract
Abstract
Background A spinal epidural arachnoid cyst (SEAC) is a rare clinical entity. We performed a systematic review of the literature to obtain information regarding demographics, clinical presentation, treatment modalities, and outcome of SEACs.
Methods A literature search was performed by using the databases PubMed/Medline, PubMed Central, Embase, Cochrane Library, Ovid MEDLINE, and Ovid Medline In-Process. A total of 170 articles were found on literature search. We found 575 cases of SEAC since 1904 for inclusion in the review including three cases which were operated by us. We studied the patient characteristics, clinical features, and management strategies, and evaluated their outcome.
Results The average age of presentation was 30 years with a male:female ratio of 1.03:1. They are commonly seen in the thoracic region (42.3%). The length of cyst was more than two vertebral levels in 85.81%. Mean symptom duration was 29 months, with most common presentation being that of compressive myelopathy. A good clinical outcome was present in symptomatic patients who had a shorter symptom duration and underwent complete surgical excision of the SEAC. Age, sex, length of lesion, and presence of dural defect did not have a bearing on the surgical outcome.
Conclusion For thoracic compressive myelopathy in a young patient, SEAC should be kept as a differential diagnosis. Surgical complete excision of the cyst with meticulous closure of the dural defect is the standard in management for a good clinical outcome.

Abstract
The authors report on a 47-year-old woman with a symptomatic thoracic spinal arachnoid cyst (SAC) who underwent a novel procedure that involves direct puncture of the SAC to visualize, diagnose, and potentially treat these rare spinal lesions. The method described utilizes 3D fluoroscopy to gain access to the SAC, followed by injection of myelographic contrast into the cyst. A characteristic "jellyfish sign" was observed that represents the containment of the contrast within the superior aspect of the cyst and a clear block of cranial flow of contrast, resulting in an undulating pattern of movement of contrast within the cyst. Following balloon fenestration of the cyst, unimpeded flow of contrast was visualized cranially throughout the thoracic subarachnoid space. The patient was discharged the following day in good condition, and subsequently experienced 1 year free from symptoms. This is the first reported case of a successful direct puncture of an SAC with balloon fenestration, and the first noted real-time fluoroscopic "behavior" of CSF within an arachnoid cyst.

Abstract
BACKGROUND Intradural spinal arachnoid cysts (ISACs) with associated neurologic deficits are encountered infrequently. Various management strategies have been proposed with minimal data on comparative outcomes. OBJECTIVE We describe the clinical and radiologic presentation as well as the outcomes of 14 surgically managed patients who presented with an ISAC and associated myelopathy. METHODS We retrospectively reviewed the clinical course of consecutive patients presenting with neurologic deficits associated with idiopathic ISACs at our institution. The diagnoses were based on preoperative magnetic resonance imaging studies followed by intraoperative and histopathological confirmation. RESULTS A total of 14 consecutive patients with ISACs (1 cervicothoracic, 12 thoracic, and 1 thoracolumbar) and associated myelopathy were identified. Syringomyelia was noted in 8 patients. All ISACs were treated with cyst fenestration and partial wall resection through a posterior approach. Preoperative neurologic symptoms were noted to be stable or improved in all patients starting at 6-week postoperative follow-up. The median (interquartile range) preoperative mJOA score was 13 (12.0-14.8), whereas the postoperative median score at a mean follow-up of 22 months (range 6-50 months) was 16 (14.0-17.0), which represents a median improvement (ΔmJOA) of 2.0 (1.3-3.0) (P < 0.001). Comparison of ΔmJOA scores between cases without and with associated syrinxes did not reveal a significant difference (P = 0.23). Postoperative magnetic resonance imaging scans revealed spinal cord re-expansion at the level of the ISAC in all cases and either complete or partial syrinx resolution in 7 of 8 cases. CONCLUSIONS Early treatment with fenestration and partial wall resection allows for cord decompression, syrinx resolution, and gradual resolution of myelopathic symptoms in most cases.

Abstract
BACKGROUND Spinal intradural arachnoid cysts (SIAC) are cerebrospinal fluid (CSF) filled sacs formed by arachnoid membranes and may be either idiopathic or acquired. Idiopathic cysts represent a separate entity and their aetiology remains uncertain. By far the most difficult differential diagnosis is distinguishing between idiopathic anterior spinal cord herniation (IASCH) and dorsal thoracic intradural arachnoid cysts (TIAC), due to their similarity in radiological appearance. Cine-mode (SSFP) is emerging as a novel technique in the diagnosis and operative planning of SIAC. METHOD Retrospective analysis of patients with idiopathic TIACs that were surgically managed at Royal North Shore Hospital and North Shore Private Hospital between November 2000 and November 2015. RESULTS Ten patients were included in this study. Age ranged from 20 to 77years with a mean age of 60years and a female preponderance. The most common clinical features were progressive gait ataxia and lower limb myelopathy. Radicular pain tends to improve following surgery, however gait ataxia may not. DISCUSSION While there are circumstances in which the distinction between dorsal thoracic intradural arachnoid cysts and idiopathic anterior spinal cord herniation are radiologically obvious, in cases where the appearances are less clear, cine-mode SSFP MRI imaging can provide an invaluable tool to differentiate these pathologies and lead the clinician towards the correct diagnosis and management. The mainstay of surgical management for dorsal TIACs is laminectomy and cyst excision or fenestration. Surgery for gait ataxia should be aimed towards preventing deterioration, while maintaining the potential for symptomatic improvement, whereas surgery for radicular pain should be curative.

Abstract
BACKGROUND Idiopathic spinal epidural arachnoid cysts (SEACs) are relatively rare lesions with diverse clinical manifestations depending on the affected spinal region and nerve roots. To assess the relationship between clinical presentation and surgical outcome, we conducted a retrospective review of medical records and neuroimages from idiopathic SEAC patients. METHODS Of 15 consecutive patients with idiopathic SEACs, 14 underwent surgical treatment at the Beijing Tiantan Hospital between January 2008 and July 2013. Case histories, clinical presentations, imaging findings, operative findings, and surgical outcomes were reviewed. RESULTS Of the 15 patients, 5 were children (median age, 13 years) and 10 were adults (median age, 35 years). The male-to-female ratio was 4:1. The median disease duration was 1 year in children and 4 years in adults. The most common manifestations were progressive paraparesis (73.3 %) and radiculopathy (66.7 %). All pediatric lesions affected thoracic segments, while 80 % of adult lesions affected lumbar segments. Fourteen patients underwent microsurgical treatment, with cyst excision in nine (combined with fistula closure in four) and partial cyst excision in five (with fistula closure in three). No recurrences were observed during follow-up (average of 23 months). Excellent outcome was achieved in six cases, good outcome in four, fair in two, and poor in two. CONCLUSIONS Idiopathic SEAC mainly affect the thoracic segments in children and the lumbar segments in adults, and often results in progressive paraparesis and radiculopathy. Early surgical intervention is suggested for progressive symptomatic patients to restore neurological function.

Abstract
Arachnoid cysts are cerebrospinal fluid collections in the spine that can present with neurological symptoms or be discovered accidentally. Intradural location of such cysts especially in the lumbosacral region is relatively rare. The association of such cysts with other congenital anomalies such as tethered cord lends evidence to the developmental origin of arachnoid cysts. We report a case of lumbosacral arachnoid cyst with tethered cord in a 6-year-old male child and discuss the etiopathogenesis and management options.

Abstract
STUDY DESIGN A retrospective analysis of patients undergoing spinal deformity correction surgery by the assistance of intraoperative computed tomography (iCT) with or without navigation system. OBJECTIVE To share our preliminary experience and analysis of the iCT navigation system applied to spinal deformity surgery. SUMMARY OF BACKGROUND DATA The iCT navigation system has been shown to improve accuracy and safety in posterior instrumentation. It not only decreased the operation time but also prevented excessive radiation exposure to the medical staff. To date, there are only few reports about the application of the iCT navigation system in spinal deformity surgery. METHODS From April 2009 to September 2010, 59 patients who had a diagnosis of scoliosis, kyphosis, or scoliokyphosis and underwent iCT-assisted surgical correction were included. Without randomization, 28 patients were operated with the iCT-navigation system, and the other 31 patients were operated with standard procedure under iCT assistance. The detailed procedures, preoperative and intraoperative images were illustrated. The accuracy of screw placement, time for screw insertion, postoperative correction rate, and iCT scanning data were analyzed. RESULTS There were significant differences between 2 groups in (1) the preoperative Cobb angle (76.2° and 62.6° in the navigation and non-navigation groups), (2) the accuracy and the revision rate of thoracic pedicle screws and total pedicle screws, and (3) the average screw insertion time. The breach rate and the revision rate of thoracic pedicle screws and total pedicle screws were significantly lower and the average screw insertion time was significantly lesser in the navigation group than in the non-navigation group. There were no statistically significant difference in (1) the breach rate and the revision rate of lumbar pedicle screws, (2) the mean iCT scanning time and time-out, (3) the mean number of fusion segments, (4) the mean number of iCT scans, and (5) the postoperative correction rate. Complications were encountered in 2 patients in the non-navigation group but none in the navigation group. There was no reoperation due to implant malposition in both groups. CONCLUSION The iCT navigation system provides desirable accuracy of posterior spinal instrumentation for patients during surgical correction of spinal deformity without radiation exposure to the medical staff, especially in thoracic spine instrumentation. Meanwhile, the iCT in itself is an effective means of assessing complex instrumentation of the spinal deformity.

Abstract
OBJECT The goal of this study was to review all cases of pediatric spinal arachnoid cysts (SACs) surgically treated at the authors' institution between 1992 and 2008 and to compare these cases to the published literature for the general population. METHODS The charts of all pediatric patients with SACs were reviewed for demographics, medical history, presenting symptoms, imaging findings, operative procedure(s), complications, and outcomes. Following a complete literature review, the pediatric data were compared with data from the general population and unique findings associated with pediatric patients were identified. RESULTS Thirty-one pediatric patients (median age 6.9 years) underwent operative intervention for SACs between 1992 and 2008 (median duration of follow-up 4.2 years). There were 17 female patients (55%) and 14 male patients (45%). Twenty-one patients (68%) presented with symptoms of radiculopathy or myelopathy. The most common presenting symptoms were pain (42%), lower-extremity weakness (39%), gait instability (32%), spasticity (19%), sensory loss (10%), and bladder dysfunction (7%). In 3 patients (10%) SACs were incidental findings. Intradural SACs were more common (18 patients, 58%) than extradural SACs (11 patients, 36%). One patient (3%) had extradural and intradural components. One patient (3%) had a purely intramedullary cyst, and 1 patient (3%) had both an intradural and intramedullary component. Of the 18 intradural SACs, 9 (50%) were located ventral to the spinal cord and 9 (50%) were dorsally situated. One dorsal intradural SAC had an intramedullary component. All extradural SACs were located dorsal to the spinal cord. Intradural SACs were primarily concentrated in the cervical and thoracic regions (67%), whereas extradural cysts were more evenly distributed between the thoracic, lumbar, and sacral regions. Of the 18 patients with intradural SACs, 13 (72%) had significant previous CNS abnormalities, compared with 3 (27%) of 11 patients with extradural SACs. There were 2 operative complications. One patient had a CSF leak treated with a lumbar drain, and the second patient had a pseudomeningocele. No patients had neurological deterioration as a result of surgical intervention. Twenty-one patients (68%) had complete remission of symptoms, 6 (19%) had improvement, 3 (10%) were stable, and 1 (3%) has worsening of symptoms with recurrence that ultimately required cystoperitoneal shunting, despite multiple failed attempts at fenestration. CONCLUSIONS Spinal arachnoid cysts are rare lesions in the pediatric population. Affected patients present with back pain, weakness, and/or gait instability. In children, SACs predominantly develop in the thoracic region and are more likely to occur intradurally, compared with SACs in the general population. Overall outcomes following surgical fenestration or excision of SACs are excellent, with complete remission or improvement of symptoms achieved in 87% of cases.

Abstract
Intradural spinal arachnoid cysts with cord compression are rare. When becoming symptomatic they cause variable symptoms involving gait disturbance, paraparesis or tetraparesis and neuropathic pain, decreasing significantly the patients' life quality. The extension of such cysts averages 3.7 vertebral bodies. The diagnosis is clinical and radiological with the use of MRI, CT myelography or a combination of both. The best treatment option is complete removal of the cyst. However, even when paresis is regressing there is no good recovery from neuropathic pain. Laminectomy approach can cause postoperative complications especially when the cyst(s) expand(s) in more than one level. Alternatively, a cyst fenestration can be performed, including the levels of the maximal spinal cord compression. The clinical outcome is as good as after the cyst resection enabling the patient to walk again. The neuropathic pain may persist and require medication. A clinical case is presented, and the literature is reviewed. In the present case we report a patient with intradural arachnoid cysts extending from T6 to L2 and causing severe gait ataxia as well as neuropathic pain and hypaesthesia. The spinal-cord was compressed at T8 and T12. Surgical treatment with partial cyst resection in the compressed levels with an interlaminar approach brought similar results as complete resection. The patient was able to walk without help which was not possible before surgery. The cysts' extension is impressive as well as the minimal operative procedure.

Abstract
STUDY DESIGN Clinical case series. OBJECTIVE To present a new innovative treatment option for cysts of the terminal ventricle. SUMMARY OF BACKGROUND DATA Invasive surgery including laminectomy and cyst fenestration has been the sole reported method of treatment for this rare pathology. METHODS Four cases of symptomatic cyst of the terminal ventricle of the spinal cord were treated by percutaneous aspiration using real-time guidance with magnetic resonance imaging (MRI) and optically-tracking navigation. RESULTS Three patients were treated successfully by this percutaneous method, and for 1 patient the treatment was converted to conventional surgery after a single unsuccessful trial of percutaneous puncture. All patients were relieved of their symptoms without any complication. Follow-up MRI revealed continued shrinkage of the cysts after both surgery and MRI-guided percutaneous fenestration. CONCLUSION MRI-navigated percutaneous aspiration can be a minimally-invasive treatment option for symptomatic cysts of the terminal ventricle, and therefore, can be indicated before more invasive surgery might be scheduled.

Abstract
Neurenteric cysts are rare congenital cysts typically located in the anterior cervical or thoracic spinal canal. The authors report on their experience with the successful treatment of a midthoracic neurenteric cyst in an 8-year-old boy. Percutaneous fenestration via a transthoracic, transvertebral approach with combined thorascopy and intraoperative MR imaging guidance was used, and the cyst showed lasting shrinkage. The authors discuss this minimally invasive technique and its limitations.

Abstract
Extradural arachnoid cysts are uncommon expanding lesions in the spinal canal, which may communicate with the subarachnoid space. Usually located in the lower thoracic spine, they may cause symptoms by compressing the spinal cord or nerve roots. We report a case of an extradural thoracic arachnoid cyst revealed by progressive spinal cord compression. CT myelography and MRI enabled diagnosis. Rapid neurological improvement was observed after surgical resection.

Abstract
STUDY DESIGN Report of 2 operated cousin cases of the multiple spinal extradural arachnoid cysts. OBJECTIVE To report the operative findings of cousin cases of the multiple spinal extradural arachnoid cysts and analyze a genetic etiology with the pedigree of all family members. SUMMARY OF BACKGROUND DATA Spinal extradural arachnoid cyst is a relatively rare condition that occupies the intraspinal space and sometimes causes neurologic disturbances. The exact etiology is unknown since most reported cases are sporadic. Minimally invasive treatments have been recently applied to a single extradural arachnoid cyst. However, it is still unknown which minimally invasive treatments can be applied to the multiple extradural arachnoid cysts. METHODS We experienced 2 cousin cases of multiple spinal extradural arachnoid cysts. Operative findings were described. The pedigree of all family members was made, and a genetic etiology was discussed. RESULTS Minimally invasive treatment was tried in Case 1. However, it failed to remove all cysts completely. Each cyst had each stalk communicating with subarachnoid space in both cases. Pedigree showed that the mode of inheritance was likely autosomal dominant. CONCLUSION When the cysts are multiple, it is necessary to identify a dural defect in each cyst. The etiology of the multiple extradural arachnoid cysts may be hereditary.

Abstract
✓Multiple spinal extradural meningeal cysts are rare. To the authors' knowledge, there have been only four reported cases in the world literature. The authors report a case of multiple spinal extradural meningeal cysts in a 31-year-old woman presenting with acute paraplegia. Magnetic resonance imaging of the thoracolumbar spine revealed multiple extradural cystic lesions extending from T-7 to T-8 and from T-12 to L-3. Intraoperative findings demonstrated a white, fibrous, and tense cyst filled with cerebrospinal fluid–like colorless fluid. Excision of the posterior wall of the symptomatic cyst was followed by immediate neurological improvement. The examination of the pathological specimen showed a thick duralike layer of collagen and an inner membrane of arachnoid that is often not found in these lesions. The final diagnosis was based on combined imaging, intraoperative, and histopathological findings. The authors review the literature and discuss the etiological, diagnostic, and therapeutic aspects of this lesion.

Abstract
Abstract
OBJECTIVE:
Preoperative magnetic resonance imaging (MRI) myelography scans demonstrated a dural defect in a 50-year-old man with an epidural arachnoid cyst who had a 29-year history of untreated weakness and numbness both lower limbs.
METHODS:
MRI scans showed a dorsal intraspinal extradural cystic lesion at the level from Th11 to L1. Although preoperative cine-MRI scans failed to display the dural defect, an MRI myelography scan showed cerebrospinal fluid in the subarachnoid space containing a cyst.
RESULTS:
The site of shunting between the subarachnoid space and the cyst was visualized as a pulsating flow void to the right of Th12. We removed the cyst wall and closed the dural defect via laminectomy.
CONCLUSION:
Because the preoperative MRI myelography scan correctly identified the existence and location of the dural defect, we conclude that MRI myelography is helpful for detecting dural defects in patients with epidural arachnoid cysts.

Abstract
Minimally invasive approaches to spinal tumors have evolved rapidly over the past 15 to 20 years as clinicians seek to avoid the morbidity and long-term dysfunction associated with traditional open surgical procedures. We review the noninvasive, percutaneous, and minimally invasive surgical techniques currently available for the treatment of spinal column and intradural spinal tumors, including minimal access thoracic corpectomy and minimal access intradural tumor surgery. The various advantages and limitations of these approaches as well as their appropriate indications and uses are also presented here. A measured understanding of surgical objectives and iatrogenic effects on patients' quality of life allows the surgeon to implement such minimally invasive approaches in the design of individualized treatment plans that range from pure palliation to definitive cure.

Abstract
✓ The authors describe the case of a high cervical, intradural extramedullary cyst located anterior to the spinal cord in a 13-year-old boy. The lesion was fenestrated percutaneously by using real-time magnetic resonance (MR) imaging guidance and a local anesthetic agent. The patient's symptom, severe exercise-induced headache, immediately resolved after treatment. Nine months later, complete disappearance of the cyst was confirmed on MR imaging and computerized tomography myelography. Magnetic resonance imageing—guided fenestration can be considered a minimally invasive option for intradural cystic lesions.
