Abstract
OBJECTIVE To analyze the outcomes of hypofractionated stereotactic radiotherapy (HFSRT) for Spetzler Martin grades 4 and 5 arteriovenous malformations (AVMs) in a pediatric population. METHODS Fourteen patients with Spetzler Martin (SM) grades IV and V large AVMs who underwent HFSRT between January 2013 and July 2019 were retrospectively reviewed. All patients received HFSRT at a dose of 30-36 Gy in 5 to 6 fractions. They were followed up annually with clinical and imaging assessments to evaluate obliteration rates. RESULTS The median age at presentation was 15 years (range 8-21 years). Ten (71%) were SM grade 4 AVMs and the rest were SM grade 5 AVMs. The majority presented with headache (8 [57%]), and 3 (21%) presented with bleeding. The median nidus volume was 39.4 cc (IQR, 31.4-52.4). Two (14%) patients had infratentorial AVMs. All of them had deep venous drainage. The median clinical follow-up duration was 75 months (range 31-107 months). There was complete obliteration of the nidus in 3 (21%) patients with a median time to obliteration of 39 months. HFSRT resulted in a reduction of the AVM volume to 12 cc or less in nearly 70% of patients. None of the patients experienced re-bleeding. 79% reported an improvement in their symptoms. CONCLUSION HFSRT is a highly effective treatment for high-grade AVMs in children, which can result in either complete elimination or significant reduction of the nidus volume or make it suitable for additional treatment, such as single-session stereotactic radiosurgery (SRS).

Abstract
PURPOSE Postoperative fever is a common problem following neurosurgery but data on the causes among paediatric patients is sparse. In this report, we determined the incidence, causes, and outcomes of postoperative fever in paediatric neurosurgical patients (< 18 years), and contrasted the findings with an adult cohort published recently from our unit. METHODS We recruited 61 patients who underwent 73 surgeries for non-traumatic neurosurgical indications over 12 months. A standard protocol was followed for the evaluation and management of postoperative fever. We prospectively collected data pertaining to operative details, daily maximal temperature, clinical features, and use of surgical drains, urinary catheters, and other adjuncts. Elevated body temperature of > 99.9 °F or 37.7 °C for > 48 h or associated with clinical deterioration or localising features was considered as "fever"; elevated temperature not meeting these criteria was classified as transient elevation in temperature (TET). RESULTS Twenty-six patients (35.6%) had postoperative fever, more frequent than in adult patients. TET occurred in 12 patients (16.4%). The most common causes of fever were aseptic meningitis (34.6%), followed by urinary tract infections (15.4%), pyogenic meningitis, COVID-19, and wound infections. Postoperative fever was associated with significantly longer duration of hospital admission and was the commonest cause of readmission. CONCLUSION In contrast to adults, early temperature elevations in paediatric patients may portend infectious and serious non-infectious causes of fever, including delayed presentation with aseptic meningitis, a novel association among paediatric patients. Investigation guided by clinical assessment and conservative antibiotic policy in keeping with the institutional microbiological profile provides the most appropriate strategy in managing paediatric postoperative fever.

Abstract
Intracranial hypotension (IH) represents a syndrome secondary to low cerebrospinal fluid pressure. This case of IH following a lumbar drain inserted before the excision of a left intraconal lesion, leading to recurrent post-operative unilateral subdural and extradural collections, was treated successfully with the evacuation of the collection and simultaneous epidural blood patch (EBP) injection. Our report provides an important perspective on the management of IH with recurrent intracranial collections and reiterates that IH should be considered when dealing with recurrent unilateral intracranial collections in the post-operative period. Evacuation with a simultaneous EBP is an effective strategy for managing IH.

Abstract
Purpose We studied the clinico-radiological features and treatment outcomes of patients with aggressive spinal haemangiomas. Methods We undertook a retrospective review of 24 patients with aggressive spinal haemangiomas managed at our centre from 2004 to 2016. The cohort was divided into two groups. Group1 included patients managed from 2004 to 2009 while Group 2 was those treated between 2010 and 2016. Clinicoradiological features and treatment outcomes were studied. Results Back pain (24/24) and myelopathy (18/24) were the most common presenting complaints. Over 80% (20/24) of patients, had involvement of the thoracic spine and more than 50% (13/24) had severe spasticity, being Nurick grade 4&5 at presentation. The various treatment modalities used were laminectomy with or without instrumented posterior fusion (10/24), corpectomy with instrumented fusion (10/24) and alcohol injection alone (4/24). Patients who were treated with surgery had significant clinical improvement at follow-up in both groups. Patients who underwent alcohol injection did not have any improvement in symptoms at follow-up. There was a change in our strategy in the later part of the series from a two staged anterior and posterior approach to a single staged posterior-only approach to address vertebral body disease with preoperative angioembolization. Conclusion Haemangiomas are benign lesions with locally aggressive behavior in some cases. Results of conservative approaches such as alcohol injection in management of these lesions are discouraging. Aggressive surgical decompression combined with preoperative adjuncts such as angioembolization with or without stabilization reduces intra operative blood loss and results in good neurological recovery even in patients with severe myelopathy.

Abstract
Postoperative fever is mostly transient and inconsequential but may portend a serious postoperative infection requiring a thorough evaluation, especially during the recent COVID-19 pandemic. We aimed to determine the incidence, causes and outcomes of postoperative fever in neurosurgical patients, as well as to evaluate a protocol for management of postoperative fever. We conducted a prospective study over 12 months, recruiting 425 adult patients operated for non-traumatic neurosurgical indications. We followed a standard protocol for the evaluation and management of postoperative fever collecting data regarding operative details, daily maximal temperature, clinical features, as well as use of surgical drains, urinary catheters, and other invasive adjuncts. Elevated body temperature of > 99.9°F or 37.7 °C for over 48 h or associated with clinical deterioration or localising features was considered as “fever” and was evaluated according to our protocol. We classified elevated temperature not meeting this criterion as a transient elevation in temperature (TET). Sixty-five patients (13.5%) had postoperative fever. Transient elevation of temperature, occurring in 40 patients (8.8%) was most common in the first 48 h after surgery. The most common causes of fever were urinary tract infections (13.7%), followed by aseptic meningitis (10.8%), wound infections and pneumonia. Various aetiologies of fever followed distinct patterns, with COVID-19 and meningitis causing high-grade, prolonged fever. Multivariate analysis revealed cranial surgery, prolonged duration of surgery, urinary catheters and wound drains retained beyond POD 3 to predict fever. Postoperative fever was associated with significantly longer duration of hospital admission. COVID-19 had a high mortality rate in the early postoperative period.

Abstract
PURPOSE During the ongoing COVID-19 pandemic, endonasal surgeries for sellar-suprasellar lesions were discouraged due to the risk of transmission of the disease. We reviewed the changes in our management protocol for these lesions as our disease understanding and preparedness evolved. MATERIALS AND METHODS This was a retrospective observational study including patients with sellar-suprasellar and clival lesions presenting to us between March and October 2020. Management protocols were divided into three phases based on the prevalence of the disease and the number of mandatory preoperative COVID-19 tests being conducted. The surgical approach used was analyzed in relation to the preferred approach during pre-COVID times, and surgical outcomes and complications were noted. RESULTS A total of 31 cases were operated during this period. During Phase I (low prevalence; no preoperative COVID testing) endonasal surgeries were largely abandoned in favor of transcranial approaches. In Phase II (medium prevalence; one preoperative COVID test) we gradually resumed endonasal surgeries for 'emergent' and 'essential' cases, and subsequently in Phase III (high prevalence; two preoperative COVID tests), we had no hesitation in performing 'elective' endonasal surgeries with additional barriers for prevention of aerosol transmission. No patient developed COVID-19 infection postoperatively. Eight HCWs in our department acquired the disease during this period, none of whom were directly involved in the surgeries for the above cohort of patients. CONCLUSIONS With a strict preoperative COVID testing protocol, adherence to proper drilling techniques and using additional barriers to prevent droplet and aerosol spread, endonasal surgeries for sellar-suprasellar lesions are safe during this COVID-19 pandemic.

Abstract
INTRODUCTION Nasal dermoid sinus cyst (NDSC) are uncommon congenital lesions in children. OBJECTIVE To review the clinical and radiological presentation and study the surgical outcomes of this uncommon lesion. METHOD Retrospective chart review of all children diagnosed with nasal dermoid from 2010 to 2020 at a tertiary referral hospital in South India was executed. The medical records were reviewed for demographics, lesion characteristics, imaging, operative details, and outcomes and literature review was performed. RESULT A total of 25 children [Mean age 3.7 yrs (Range 2-9 yrs)] with nasal dermoid sinus cysts were treated in the last decade. While 13 presented with a sinus, 11 presented with cyst and 1 had both. The lesions mainly involved the upper third of the nose in 10 children, middle one third in 6 and upper one third in 9 children. All underwent Magnetic Resonance Imaging, in 11 Computed Tomography also was done. A flow chart of the lesion characteristics and its management has been presented. Intraoperatively intracranial extension was present in four children. The approach to intracranial extension and corresponding literature review has been presented. Follow up ranged from one to six years. (Median 3.5 yrs) and no recurrence or complication was noted. CONCLUSION Nasal dermoid is an uncommon congenital anomaly. Preoperative evaluation must include imaging to assess extent and rule out intracranial extension. Surgical strategy depends on whether presentation is as sinus or cyst and location and extent of lesion. All surgical approaches have a good surgical and cosmetic outcome.

Abstract
Introduction: Synovial sarcoma is a rare mesenchymal malignant neoplasm that accounts for less than 10% of soft tissue sarcomas. About 95% of the sarcomas occur in the extremities. Primary synovial sarcomas of the spine are a rare tumor arising from the paravertebral regions, paraspinal muscles or epidural spaces.Purpose: To report an atypical radiological presentation of synovial sarcoma of the thoracic spine mimicking a nerve sheath tumor in an elderly adult and describe the management with review of the literature.Clinical presentation: A forty-six-year-old lady presented with clinical features of a thoracic intradural extramedullary cord compression at T7 level. She was Nurick grade 4 at presentation. MRI of the Thoracic spine with whole spine screening showed a contrast enhancing intradural extramedullary tumor at the T7-8 level; the tumor was exiting out through the left T7-8 neural foramina with foraminal widening. The possibility of a schwannoma was considered.Intervention: She underwent a T7-8 laminectomy and total excision of the tumor followed by posterior fusion. The biopsy was reported as synovial sarcoma. She subsequently underwent radiation and chemotherapy. She had marked improvement in her Neurological status and remained disease free at six months follow-up.Conclusion: Synovial sarcoma of the spine is a rare mesenchymal malignant neoplasm. One needs to consider Synovial sarcoma as one of the differential diagnosis of intradural tumors of the spine.
