Background: The estimation of survival is extremely important for metastatic disease in the spine. The aim of this study was to determine the factors affecting the outcome of patients with spinal metastasis, primarily the character of neurologic deficit and the histopathology of the tumor., Method: A retrospective examination was made of 158 patients with spinal metastasis who were followed up in our clinic between 2010 and 2020 and underwent surgical intervention. The patients were examined in respect of demographic characteristics, the primary tumor, comorbidities, preoperative-postoperative visual aAnalog scale scores, preoperative-postoperative neurologic examinations and neurologic deficit if present and ambulation status, postoperative survival duration, tumor localization, characteristics of the surgeries, complications, the Karnofsky Performance Scale, revised Tokuhashi, and Tomita scores., Results: Spinal metastasis was seen more frequently in males (72.8% male, 27.8% female). Male gender, multiple level involvement, intradural localization, and Karnofsky Performance Scale <70 were seen to cause a shorter survival time. Patients with a primary focus of hematologic malignancy, breast cancer, and lymphoma had a longer survival. The revised Tokuhashi and Tomita scores were observed to be successful in the prediction of survival. A decrease in postoperative visual analog scale score had a positive effect on functional survival. The absence of preoperative neurological deficit and the patient's ability for preoperative and postoperative ambulation affected survival positively. The overall survival period decreased in patients who were mobilized in the early postoperative period but became nonmobile in the late period, and in those who were nonmobile in both the early and late postoperative periods., Conclusions: The neurologic and ambulatory status, the Tomita and Tokuhashi scores, intradural localization, and gender are the factors with a significant effect on prognosis., (Copyright © 2024 Elsevier Inc.

Background The treatment of spinal schwannomas, which is the most common nerve sheath tumor, is total microsurgical resection. The localization, size and relationship with the surrounding structures of these tumors are crucial in terms of preoperative planning. A new classification method is presented in this study for the surgical planning of spinal schwannoma. Methods All patients who underwent surgery for spinal schwannoma between 2008 and 2021 were reviewed retrospectively, along with radiological images, clinical presentation, surgical approach, and postoperative neurological status. Results A total of 114 patients, 57 male, and 57 females were included in the study. Tumor localizations were cervical in 24 patients, cervicothoracic in one patient, thoracic in 15 patients, thoracolumbar in eight patients, lumbar in 56 patients, lumbosacral in two patients, and sacral in eight patients. All tumors were divided into seven types according to the classification method. Type 1 and Type 2 groups were operated on with a posterior midline approach only, Type 3 tumors were operated on with a posterior midline approach and extraforaminal approach, and Type 4 tumors were operated on with only an extraforaminal approach. While the extraforaminal approach was sufficient in type 5 patients, partial facetectomy was required in 2 patients. Combined surgery including hemilaminectomy and extraforaminal approach was performed in the type 6 group. A posterior midline approach with partial sacrectomy/corpectomy was performed in Type 7 group. Conclusion Effective treatment of spinal schwannoma depends on preoperative planning, which includes correctly classifying tumors. In this study, we present a categorization scheme that covers bone erosion and tumor volume for all spinal localizations., Competing Interests: The authors declare that they have no conflict of interest., (Thieme.

Aim: Arachnoid cysts in the spinal canal account for 1%-3% of all spinal canal lesions. There is no consensus on surgical treatment yet. Dural defect repair is crucial in surgical treatment patients with an extradural component. Fenestration or total resection of the spinal arachnoid cyst is among the preferred methods. This study aimed to examine a series of surgically treated spinal arachnoid cysts in light of the literature., Material and Methods: This was a retrospective study of patients treated in the Istanbul Umraniye Training and Research Hospital Neurosurgery Clinic. A total of 18 patients with spinal arachnoid cysts underwent surgical treatment between 2012 and 2021. All patients were assessed before and after surgery for muscle strength, pain, sensory changes, and bowel-bladder symptoms. All patients underwent magnetic resonance imaging and computed tomography for diagnosis and treatment., Results: Among the 18 patients, 8 were men and 10 were women, with a mean age of 43.7 (25-66) years. Congenital conditions were discovered in 15 of the patients, 2 after lumbar drainage and 1 after spinal anesthesia. Intradural extramedullary and intra-extradural cysts were found in 17 patients and 1 patient, respectively. The cyst was smaller than level 3 in 14 patients and greater than level 3 in 4 patients. Cyst excision and cyst fenestration were performed in 11 and 7 patients, respectively. Cyst excision was performed in four of the patients who underwent cyst fenestration because their complaints did not improve., Conclusion: Surgery should be considered in patients with symptomatic spinal arachnoid cysts. Fenestration may be a suitable alternative, especially if magnetic resonance imaging reveals no intracystic adhesion or trabeculation. Residual and recurrence rates are high in patients with a history of intradural intervention, adhesions, or trabeculation. When there is trabeculation, the best option is cyst removal.

Aim: To propose a treatment algorithm, and to assess spinal instability in patients diagnosed with spinal lymphoma., Material and Methods: Demographics, symptoms, tumor level and location, and presence of spinal instability were reviewed in 22 patients with spinal lymphomas. Each patient's neurological state was reviewed using the American Spinal Injury Association and modified McCormick scale scores, and spinal instability was assessed using the Spinal Instability Neoplastic Score (SINS)., Results: Initially, percutaneous biopsy was performed in 16 patients, and open biopsy was performed in 6 patients. Eight of the patients who underwent percutaneous biopsy were followed up with hematological examination alone, as they had no additional complaints. The SINS was used to evaluate the presence of spinal instability, and the type of surgery to be performed was decided accordingly. In the second surgery, decompression and stabilization were performed in 5 of the remaining 8 patients, and only decompression was performed in 3 of them. Neurological improvement was observed in 6 of 7 patients with acute neurological deficit., Conclusion: Percutaneous biopsy for tissue diagnosis is the first step in the management of spinal lymphomas. Patients without neurological deficit should be referred for hematological examination. Those with acute neurological deficit require emergency surgery, and those with chronic symptoms must undergo operation for decompression and/or stabilization. This study confirmed the safety of the SINS in the evaluation of spinal instability in spinal lymphoma cases.

Meningiomas are benign, slow-growing tumors originating from arachnoid gap cells. They constitute 15%-20% of all intracranial tumors in adults and 04%-4% in the pediatric age group. Meningiomas in the posterior fossa in the pediatric period do not initially come to mind. In the case presented here, there was a cystic meningioma showing heterogenous contrast and obstructive hydrocephaly was observed associated with 4th ventricle pressure. the tumor was totally removed, then the ventriculo peritoneal shunt was applied., (Copyright: © Neurosciences.)

Background: Spinal schwannomas are commonly presented with minor symptoms, including radicular pain, sensory deficits, and minor neurologic deficit. Acute neurologic deterioration is uncommon., Case Description: In this study, a case of cauda equina schwannoma presented with acute neurologic deficit after movement of spinal schwannoma is presented., Conclusions: It is noted that movement of spinal schwannoma and resultant acute neurologic deterioration should be considered during the follow-up., (Copyright © 2020 Elsevier Inc.

Aim: To evaluate the clinical and economic outcomes of the adoption of the enhanced recovery after spine surgery (ERSS) program in patients undergoing spine instrumentation., Material and Methods: This study described the introduction of the ERSS program, and we compared 86 consecutive patients who participated in ERSS with a retrospective cohort of 88 patients who underwent the same surgery before the implementation of this program. Groups were compared in terms of age, sex, body mass index (BMI), American Society of Anesthesiologist (ASA) physical scores, operative time, comorbidities, intraoperative blood loss, blood transfusion rate, first oral intake, time of first mobilization, length of hospital stay, preoperative and postoperative pain scores using a numeric pain rating scale, 30-day readmission and complication rates, and total cost., Results: Groups were similar in terms of age, sex, BMI, ASA scores, and comorbidities. Intraoperative blood loss, blood transfusion rate, and length of hospital stay were lower in the ERSS group. First oral intake and first mobilization occurred earlier in the ERSS group. Postoperative pain scores were significantly lower in the ERSS group. Operative time, readmissions, or complications at 30 days did not statistically differ between the two groups. The ERSS group was found to be significantly cost effective., Conclusion: ERSS is feasible, comprehensive, and cost effective for spine instrumentation with better perioperative outcomes.
