Spinal cord injury (SCI) is a devastating neurological disorder that has a substantial detrimental impact on a person’s quality of life. The estimated global incidence of SCI is 40 to 80 cases per million people and around 90% of cases are traumatic. Various etiologies can be recognized for SCI, and post-traumatic SCI represents the most common of these. Patients worldwide with SCI suffer from a persistent loss of motor and sensory function, which affects every aspect of their personal and social lives. Given the lack of effective treatments, many efforts have been made to seek a cure for this condition. In recent years, thanks to their ability to regenerate tissue and repair lost or damaged cells, much attention has been directed toward the use of stem cells (embryonic, induced pluripotent, mesenchymal, hematopoietic), aimed at restoring the functional integrity of the damaged spinal cord and improving a functional recovery including sensory and motor function. In this paper, we offer an overview of the benefits and drawbacks of stem cell therapy for SCI based on clinical evidence. This report also addresses the characteristics of various stem cell treatments, as well as the field’s likely future. Each cell type targets specific pathological characteristics associated with SCI and demonstrates therapeutic effects via cell replacement, nutritional support, scaffolds, and immunomodulation pathways. SCI accompanied by complex pathological processes cannot be resolved by single treatment measures. Stem cells are associated with the adjustment of the expression of neurotrophic factors that help to achieve better nutrition to damaged tissue. Single-cell treatments have been shown in some studies to provide very minor benefits for SCI in multiple preclinical studies and a growing number of clinical trials. However, SCI damage is complex, and many studies are increasingly recognizing a combination approach such as physical therapy, electrical stimulation, or medication therapy to treatment.

(1) Background: The aim of the present study was to evaluate our institutional outcome in tuberculum sellae meningioma (TSM) patients treated microsurgically using multiple skull base approaches, including a transcranial approach and an extended endonasal transsphenoidal approach. (2) Materials and Methods: This is a retrospective study that includes 34 patients with TSM. The study aimed to observe the efficacy of the different common approaches used by a single neurosurgeon. All the patients were evaluated preoperatively and during follow-up with campimetry, head CT scan, and post-contrast MRI. (3) Results: After a transcranial approach, visual acuity improved in 86.20%, was stable in 10.34%, and deteriorated in 3.45%. Through transsphenoidal surgery, vision improved in 80%, was static in 20%, and deteriorated in 0%. Transcranial approaches included pterional, mini-bifrontal basal, and supraciliary keyhole microscopic craniotomies. Gross total removal was performed in 58.82%, near total in 10.34%, and partial removal in 3.45%. The transcranial/supraciliary keyhole endoscopic-assisted approach showed a gross total removal rate of 80%, and near total in 20%. The transsphenoidal approach showed a gross total removal rate of 60%, near total in 20%, and partial removal in 20%. (4) Conclusion: Endoscopic-assisted keyhole supraciliary mini craniotomy for resection of tuberculum sellae meningioma offers low morbidity and good visual outcome. The endonasal route is preferred for the removal of TSM when they are small and midline placed. The major limitation of this approach is a narrow surgical corridor and the restriction on midline-placed lesions. Gross total removal was better achieved with mini-bifrontal basal and pterional craniotomies.

(1) Introduction: Primary intraosseous osteolytic meningiomas (PIOM) are non-dural-based tumors predominantly presenting an osteolytic component with or without hyperostotic reactions. They are a subset of primary extradural meningiomas (PEM). In this study, we present a peculiar case with a systematic literature review and propose a new classification considering the limitations of previous classification systems. (2) Materials and Methods: Using a systematic search protocol in Google Scholar, PubMed, and Scopus databases, we extracted all case studies on PIOM published from inception to December 2020. A 46-year-old female patient form Dhaka, Bangladesh, was also described. The search protocol was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. (3) Results: Here, we present a 46-year-old female patient with PIOM who successfully underwent bifrontal craniotomy and gross total removal (GTR) of the tumor. At 6-month follow-up, no tumor recurrence was shown. Including our new case, 55 total cases from 47 articles were included in the analysis. PIOMs were in closer frequency among males (56.4%) and females (43.6%). The most common tumor location was the frontal and parietal calvarium, most commonly in the frontal bone (29.1%). Surgical resection was the predominant modality of treatment (87.3%); only 1.8% of patients were treated with radiotherapy, and 5.4% received a combination of surgery and radiotherapy. Gross total resection (GTR) was achieved in 80% of cases. Extracranial extension was reported in 41.8% of cases, dural invasion in 47.3%, and recurrence in 7.3%. Whole-body 68 Ga-DOTATOC PET/CT has also been reported as a useful tool both for differential diagnosis, radiotherapy contouring, and follow-up. Current treatments such as hydroxyurea and bevacizumab have variable success rates. We have also suggested a new classification which would provide a simple common ground for further research in this field. (4) Conclusions: Surgical resection, especially GTR, is the treatment of choice for PIOM, with a high GTR rate and low risk of complications and mortality. More research is needed on the differential diagnosis and specific treatment of PIOM.

Background: Noncommunicating extradural spinal arachnoid cysts are extremely rare. They are believed to arise from congenital defects in the dura mater and become enlarged as a consequence of increased cerebro-spinal fluid (CSF) pressure within the subarachnoid space. Most retain a communicating pedicle through which the extradural cyst maintains connection with the subarachnoid space, and only rarely does this communication become sealed. The optimal treatment consists of complete surgical removal of the cyst with ligation of the communicating pedicle. Case Description: A 29-year-old male presented with a progressive spastic paraparesis of 6 months’ duration. The MRI showed a circumscribed intradural extramedullary cystic lesion located from D11-L2. Notably, peroperatively, the cyst appeared to be entirely extradural, without a communicating intradural pedicle. Further, no CSF leak was observed even after Valsalva maneuvers. Following surgical extirpation of the cyst, the patient sustained an uneventful recovery within 1 postoperative month. Conclusion: Noncommunicating extradural arachnoid cysts are extremely rare causes of spinal cord compression and should be fully excised.

Intracranial aneurysms are serious vascular conditions that pose a significant risk of life-threatening subarachnoid hemorrhage (SAH) if ruptured. Over the past century, the surgical management of aneurysms has undergone remarkable advancements, with aneurysm clipping emerging as a cornerstone treatment. This review traces the historical evolution of aneurysm clipping, from the formidable challenges of early 20th-century brain surgery to the sophisticated techniques used today. Key milestones include Victor Horsley’s pioneering ligation methods, Harvey Cushing’s foundational neurosurgical principles, and Walter Dandy’s groundbreaking intracranial aneurysm clipping in 1937. Technological innovations have played a crucial role in advancing the field. The introduction of the operating microscope by M.G. Yasargil in the 1960s and Charles Drake’s fenestrated clip design in 1969 significantly improved surgical precision and outcomes. The emergence of endovascular techniques, particularly Guglielmi’s detachable coils (GDC) in the 1990s, provided a minimally invasive alternative to clipping. Today, both approaches remain valuable, with treatment selection based on aneurysm characteristics and patient-specific factors. Modern aneurysm clipping has further benefited from cutting-edge imaging technologies, intraoperative monitoring systems, and refined clip designs, enhancing both safety and efficacy. Landmark comparative studies, such as ISAT and BRAT, have provided critical evidence guiding treatment strategies and optimizing patient outcomes.

(1) Background: Meningiomas are usually benign encapsulated intracranial tumors with well-defined borders that offer a high chance of cure with complete removal. The aim of this study was to evaluate the association between preoperative MRI features and surgical plane of cleavage. (2) Materials and Methods: This was a cross-sectional observational study conducted in the Department of Neurosurgery, Bangabandhu Sheikh Mujib Medical University. Data were recorded from 48 study participants with confirmed intracranial meningioma and analyzed by IBM SPSS (version 23). (3) Results: The highest incidence of intracranial meningioma was observed in the third decade of life of our study participants. The female to male ratio was 1.82:1. The most common location of meningiomas was convexity (29.16%), sphenoid wing (22.91%), parasagittal (20.83%), and falcine (14.58%). Most of the patients (68.8%) had medium-sized tumors, and 75.0% exhibited hyperintense signal change in the tumor parenchyma on T2-weighted imaging. One-third (33.3%) of patients were characterized as no edema, focal edema, and lobar/hemispheric edema. There was no statistically significant association between tumor size and types of surgical cleavage plane. Different signal intensities of tumor parenchyma, as well as types of peritumoral edema, showed no statistically significant association with surgical cleavage plane (p > 0.05). (4) Conclusion: There was no association among the size of the tumor, extent of peritumoral edema, the intensity of the tumor on T2-weighted images, and the types of surgical cleavage plane. Future studies with larger sample sizes are required to find out more precise findings.
