Background and Study Aims For endoscopic fenestration of middle cranial fossa arachnoid cysts (MCFACs), the decisions on the location and number of stomas are key issues in the operation. However, research on this particular topic has been limited. Thus, this study aimed to compare single-stoma versus multiple-stoma endoscopic fenestration for treating Galassi type III MCFACs. Patients and Methods This retrospective study included 86 patients with Galassi type III MCFACs treated with endoscopic fenestration. Single-stoma fenestration to the basal cistern was performed in 37 cases, while multiple-stoma fenestration to the basal cistern and the carotid cistern was performed in 49 cases. Clinico-radiological profiles and follow-up data were analyzed. Results The rate of symptom relief was 83.7%(72/86), and the rate of cyst shrinkage was 96.5%(83/86). Postoperative ipsilateral subdural effusion, which was significant(P=0.042), and non-infectious fever were the two most common complications in the single-stoma and multiple-stoma groups. No significant differences in intraoperative nerve injury, vascular injury, proportion of cases with cyst reduction, and symptom remission rate were observed between both groups. The rates of cyst recurrence and secondary surgery in the single-stoma group were higher than those in the multiple-stoma group, although the difference was not significant. Conclusion Endoscopic fenestration is an effective and minimally invasive approach for treating Galassi type III MCFACs. Single-stoma and multiple-stoma have the same curative effect.

Background: Acute subdural hematoma (ASDH) is a common disease and craniotomy is the first choice for removing hematoma. However, patients for whom craniotomy or general anesthesia is contraindicated are increasing due to population aging. In our department, we perform burr hole surgery under local anesthesia with urokinase administration for such patients. We compared the patient background and outcomes between burr hole surgery and craniotomy to investigate the surgical safety criteria for burr hole surgery. Methods: We reviewed 24 patients who underwent burr hole surgery and 33 patients who underwent craniotomy between January 2010 and April 2020 retrospectively. Results: The median age of the burr hole surgery group was older (P = 0.01) and they had multiple pre-existing conditions. Compared with the craniotomy group, neurological deficits and CT findings were minor in the burr hole surgery group, whereas the maximum hematoma thickness was not significantly different. The hematoma was excreted after a total of 54,000 IU of urokinase was administered for a median of 3 days. The Glasgow Coma Scale score improved in all patients in the burr hole surgery group and there were no deaths. Age, especially over 65 y.o., (OR 1.16, 95% CI 1.04–1.30) and the absence of basal cistern disappearance (OR 0.04, 95% CI 0.004–0.39) were significant factors. Conclusion: Burr hole surgery was performed safely in all patients based on the age, especially older than 65 y.o., and the absence of basal cistern disappearance. ASDH in the elderly is increasing and less invasive burr hole surgery with urokinase is suitable for the super-aging society.

BACKGROUND Coccidioidomycosis is a primarily self-limiting fungal disease endemic to the western United States and South America. However, severe disseminated infection can occur. The authors report a severe case of coccidioidal meningitis that appeared to be a subarachnoid hemorrhage (SAH) on initial inspection. OBSERVATIONS A man in his early 40s was diagnosed with coccidioidal pneumonia after presenting with pulmonary symptoms. After meningeal spread characterized by declining mental status and hydrocephalus, coccidioidal meningitis was diagnosed. The uniquely difficult aspect of this case was the deceptive appearance of SAH due to the presence of multiple aneurysms and blood draining from the patient’s external ventricular drain. LESSONS Coccidioidal infection likely led to the formation of multiple intracranial aneurysms in this patient. Although few reports exist of coccidioidal meningitis progressing to aneurysm formation, patients should be closely monitored for this complication because outcomes are poor. The presence of basal cistern hyperdensities from a coccidioidal infection mimicking SAH makes interpreting imaging difficult. Surgical management of SAH can be considered safe and viable, especially when the index of suspicion is high, such as in the presence of multiple aneurysms. Even if it is unclear whether aneurysmal rupture has occurred, prompt treatment is advisable.

Chronic subdural hematoma (CSDH) is a common form of intracranial hemorrhage in the aging population. We aimed to investigate the predictive factors for atorvastatin efficacy as a monotherapy for moderate CSDH. We retrospectively reviewed the medical records of patients who were diagnosed with moderate CSDH and received atorvastatin monotherapy between February 5, 2014, and November 7, 2015, in multiple neurosurgical departments. Univariate, multivariate and receiver operating characteristic curve analyses were performed to identify the potential significant factors indicative of the good therapeutic efficacy or poor therapeutic efficacy of atorvastatin for mild CSDH, such as age, sex, history of injury, Markwalder grading scale–Glasgow Coma Scale (MGS-GCS), Activities of Daily Life-the Barthel Index scale (ADL-BI), American Society of Anesthesiologists Physical Status classification system (ASA-PS), blood cell counts, serum levels and computed tomography findings. A total of 89 patients (75 men and 14 women) aged 24–88 years (mean age 61.95 ± 15.30 years) were followed-up for 24 weeks. Computed tomography findings at admission showed mixed-density hematoma in 22 patients, isodense hematoma in 13 patients, high-density hematoma in 26 patients, and low-density hematoma in 28 patients. In total, 3, 80, and 6 patients had MGS-GCS grades of 0, 1, and 2, respectively. The efficacy rate at 6 months was 87.6% (78/89). Eleven patients were switched to surgery due to a worsened neurological condition, of whom 8, 1, 1, and 1 had high-density, low-density, isodense and mixed-density hematomas, respectively. These patients were switched to surgery over a range of 2–27 days, with a median interval of 12 days after the medication treatment. Univariate and multivariate analyses, confirmed by ROC curves, revealed that high-density hematoma, basal cistern compression, and hematoma volume to be independent risk factors for the efficacy of atorvastatin monotherapy in patients with moderate CSDH. Atorvastatin is an effective monotherapy for the treatment of mild CSDH. High-density hematoma, basal cistern compression, and hematoma volume are independent predictors of the efficacy of atorvastatin as a non-surgical treatment. The results suggested that ADL-BI was more sensitive than the MGS-GCS and ASA-PS for determining patient outcomes in our moderate CSDH cohort.

Introduction: Traumatic Brain Injury (TBI) has become an epidemic and remains the leading cause of death and disability in people of 2nd to 4th decade. Road Traffic Accidents (RTA) are responsible for the majority of cases. Primary brain injury sustained on impact and secondary brain injury that develops in following hours and days contribute together to overall injury and decides ultimate outcome. The goal of management in any TBI patient aims to prevent secondary brain injury. Understanding the importance of Intracranial Pressure (ICP) is key to minimise secondary injury. Decompressive hemicraniectomy is a novel technique of reducing ICP in patients of severe brain injury. It’s judicious and timely performance not only saves life but also prevents the dreaded consequences of raised ICP. Aim: To evaluate the role of early decompressive hemicraniectomy in improving the survival rate among patients of severe TBI and analysing the important factors (glasgow coma scale, airway status, timing of surgery) affecting the surgical outcome. Materials and Methods: It was a retrospective study conducted at the Department of Neurosurgery, Veer Surendra Sai Institute of Medical Sciences and Research, Burla, Odisha, India between September 2016 to March 2020. Case records of 60 patients of TBI who had undergone unilateral Decompressive Craniectomy (DECRA) were analysed. The decision for decompressive hemicraniectomy was purely based upon Glasgow Coma Scale GCS) and Computed Topography (CT) findings. The presence of an evacuable mass lesion, diffuse oedema and obliteration of basal cistern in CT was considered to be the most important criteria for the early decompressive procedure. Patients were assessed until their discharge from ward. Statistical analysis was performed by statistical package for science version 12. Results: A total of 60 patients with severe TBI, who underwent DECRA were analysed. Road Traffic Accident (RTA) was the predominant mechanism of injury. All had presence of a surgically evacuable mass lesion along with compression/obliteration of the basal cistern. The majority of mass lesions (n=42) were frontotemporal contusions (70%). Forty patients of total achieved good surgical outcome (66.67%) and rest 20 patients (33.33%) had poor outcomes. Overall incidence of complications was around 40%. The most important factors associated with good outcomes were GCS of 7 and and above, patent airway, and early surgery. Conclusion: Decompressive hemicraniectomy is a novel technique of reducing ICP which acts by directly breaking the rigid box phenomenon of Monro-Kellie doctrine. However patient selection, prompt decision, earliest intervention, adoption of standard technique of DECRA and post operative critical care management are important aspects behind the successful outcome.

Epidermoid cysts are slow-growing congenital tumors developed from ectodermal inclusions. They usually sit at the cerebellopontine angle or basal cistern, their location in the fourth ventricle are exceptional.We report the case of a 44-year-old patient admitted to the Neurosurgery department for chronic daily headaches with visual impairment recently aggravated by cerebellar stato-kinetic syndrome.The diagnosis of epidermoid cyst of the fourth ventricle was suspected on MRI especially in diffusion sequence and then confirmed by the anatomopatological studies. Subtotal surgical excision was performed. The evolution was marked by the disappearance of clinical signs. Radiological and clinical follow up were indicated.
