RESUMEN
Anterior cervical corpectomy and fusion is considered the mainstay of surgical treatment in cervical pathology. Expandable and nonexpandable cages are preferred over autogenous bone graft because of donor-related morbidity. However, the choice of the cage type remains a debatable topic as studies report conflicting results. Thus, we evaluated the outcomes of expandable and non-expandable cages following cervical corpectomy. Studies were searched in various electronic databases (MEDLINE, PubMed, EMBASE, CINAHL, Scopus, and Cochrane) between 2011 and 2021. Forest plot was made to compare the radiological and clinical outcomes between expandable and non-expandable cages following cervical corpectomy. Altogether, 26 studies (1,170 patients) were included in the metaanalysis. The mean change in segmental angle was significantly greater in the expandable cage group than in the non-expandable cage group (6.7° vs. 3.0°, p <0.001). The mean subsidence rate was lower in the expandable cage group (6% vs. 41%, p <0.001). The mean fusion rate was lower (93% vs. 98%, p =0.06) and the mean displacement rate was significantly higher in the expandable cage group (29% vs. 5%, p <0.05). The mean reoperation rate was higher in the expandable cage group (16% vs. 2%, p >0.05). The improvement in segmental angle is better with expandable cages. Higher subsidence is a major problem with non-expandable cages, but it seems to be beneficial as evidenced by the high fusion rate and minimal effect on clinical outcome in patients with this cage.
RESUMEN
Objective After anterior cervical corpectomy expandable cage were used with or without using anterior cervical plate for structural support are being preferred over autologous bone graft and other types of cages. Nowadays, the preferable type of cages and application of anterior cervical plate remain a debatable topic with studies giving divergent results. The purpose of this study is to evaluate the outcomes of expandable cages used alone or expandable cage used with anterior cervical plate following anterior cervical corpectomy. Materials and Methods This study was conducted on 100 patients from January 2019 to December 2021 and all patients were undergone anterior cervical corpectomy and fusion and divided in two groups with expandable cage only (Group A) and expandable cage with anterior cervical plate (Group B). Various long-term benefits and radiological outcomes were studied in both groups. Statistical Analysis and Results In this study, 100 patients were included and all patients underwent corpectomy followed by insertion of expandable cage alone or with anterior cervical plate. There was an improvement in C2-C7 Cobb's angle in group B was significantly higher than group A ( p < 0.05) and decrease in Nurick's scale score in group B was significantly higher than group A ( p < 0.05). The outcomes were measured with fusion rate (94%), subsidence rate (15%) and change in C2-C7 Cobb's angle was 4 degrees in this study. Conclusion Expandable cage with or without anterior cervical plate was used after anterior cervical corpectomy for various cervical pathological conditions. In this study, we conclude the long-term benefits and radiological outcomes of two groups as expandable cage was used alone or with additional application of anterior cervical plate. In this study, the results were more in favor of additional application of anterior cervical plate as compared with expandable cage alone and more studies were required in future for more established long-term benefits and drawbacks.
RESUMEN
Background Brain tumors may be associated with high morbidity, and psychiatric symptoms may be an early manifestation. It is important to address mental symptoms as early as possible because they are prone to develop psychiatric comorbidities in future. If untreated, these situations may worsen and lead to burden upon caregivers. Methods A total of 176 brain tumor patients between January 2021 and January 2022 constituted the sample size. All recently diagnosed cases of brain tumor with age equal to or more than 18 years who can comprehend and answer questionnaires were included. Patients with a long history of brain tumor or who had a history of a psychiatric illness other than presenting symptoms or any other serious medical illness were excluded. Results Twenty-seven percent of brain tumor patients had psychiatric symptoms. Depressive symptoms were the most common, associated with 24% of patients, followed by anxiety disorders. Psychiatric disorders were more common in supratentorial compared to infratentorial tumors. Psychiatric symptoms seem to be associated more commonly with malignant tumors and peritumoral edema. Among malignant tumors, depressive symptoms tend to be related with high-grade glioma, and among benign tumors, they were more common in meningioma. No predilection to laterality and anatomical lobe involvement is reported. Conclusion Screening of psychiatric disorders should be a routine in brain tumor patients. An integrated approach is required to treat brain tumor patients. Healthcare professionals should be more vigilant about the onset of psychiatric symptoms and the need of palliative care to improve the quality of life.
RESUMEN
Background: The aim of the study was to evaluate the advantage of performing planned surgery using customized three-dimensional (3D) printed models versus performing surgery without using 3D printed models in patients with craniovertebral junction (CVJ) anomalies and traumatic CVJ fractures and dislocations. Methods: Forty-two patients with CVJ anomalies, who were planned for operative intervention in the Department of Neurosurgery at SMS Hospital from March 2019 to February 2021, were randomly divided into two groups and analyzed. First group was operated after rehearsal on a customized 3D printed model whereas the second group underwent operative intervention without the rehearsal of surgery on the 3D printed model. Results: Forty-two patients were enrolled for the study. Twenty-five of these patients had developmental CVJ anomalies, 16 had post traumatic Atlantoaxial dislocation (AAD), and one had congenital AAD. Twenty-three patients underwent surgical intervention using 3D printed models and 19 without using 3D printed models. The outcome in the two groups was compared using modified Japanese orthopedic association score (mJOA), recovery rate, incidence of complications such as screw malposition, postoperative neurological deterioration, vertebral artery (VA) injury, and radiological improvement based on Atlanto-Dental interval, the distance of the tip of dens from Wackhenheims clivus canal line, and the distance of tip of dens from the Chamberlain's line. The improvement in mJOA score postoperatively was found to be statistically significant in study group (P < 0.001) as compared to control group (P = 0.06). Recovery rate was better in study group than in control group (P = 0.023). In study group, the incidence of screw malposition and VA injury was lower than control group. Three patients deteriorated neurologically postoperatively in the control group and none in the study group. The average improvements in the radiological parameters were found to be better in study group as compared to control group postoperatively. Conclusion: The authors conclude that 3D printed models are extremely helpful in analyzing joints and VA anatomy preoperatively and are helpful in unmasking any abnormal bony and vascular anatomy effectively, making the surgeon confident about the placement of the screws intraoperatively. These 3D models help in intraoperative error minimization with better neurological outcomes in postoperative period. In our opinion, these models should be included as a basic investigation tool in patients of CVJ abnormalities. The models also offer other advantages such as preoperative simulation, teaching modules, and patient education.
RESUMEN
OBJECTIVE: To evaluate the usefulness and degree of perfusion abnormalities in pediatric head injury patients by using computed tomography perfusion (CTP) and to assess its co-relation with neurologic outcome based on Glasgow Outcome Scale Extended Pediatric revision (GOSE-P). METHODS: Prospective evaluation of pediatric head injury patients who were taken for CTP after admission and then on discharge. We evaluated 5 regions of interest: orbitofrontal cortex, internal capsule, thalamus, caudate nucleus, and sensorimotor cortex for cerebral blood perfusion. The patient's clinical and radiologic findings were analyzed, correlated with cerebral blood flow (CBF) and MTT (mean transient time), and the outcome assessed using the GOSE-P scale on 3-month follow-up. RESULTS: Both CBF and MTT showed a correlation with the GOSE-P scale. In mild head injury patients, the Pearson correlation of GOSE-P with mean CBF and mean MTT was -0.11 and 0.56, respectively (P < 0.05) in the sensorimotor cortex; in moderate head injury patients the Pearson correlation of GOSE-P with mean CBF in the caudate nucleus and mean MTT in the internal capsule was -0.32 and 0.36, respectively (P < 0.05); and in severe head injury patients, the Pearson correlation of GOSE-P with mean CBF and mean MTT was -0.78 and 0.56, respectively (P < 0.05) in the caudate nucleus, which had the highest Pearson co-relation among the regions studied. CONCLUSIONS: We conclude that CBF and MTT are 2 important radiologic parameters that can be used as prognostic indicators in pediatric head injury patients.

AIM: To evaluate all serum biomarkers in sports-related concussion injury (SRC) to determine diagnostic validity, changes with symptom severity, and return to play, as well as detect early changes in serum concentration. MATERIAL AND METHODS: Studies were searched in various electronic databases (MEDLINE/PubMed, EMBASE, CINAHL, Scopus and Cochrane databases) from their commencement to May 2021. Studies were included if athletes aged 12 years and older were diagnosed with a concussion injury and evaluated using serum biomarkers. Studies including athletes with injuries other than concussion injuries were excluded. Articles with fewer than 20 concussed athletes were excluded. There were 1782 articles identified. RESULTS: After exclusion a total of 17 articles qualified for systematic review. S100 calcium binding protein ? (S-100?) and ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1) showed promising results in distinguishing concussed athletes from contact sports and non-athlete controls. Most of the serum biomarkers increased within 6 hours of SRC. Serum neurofilament light protein (NFL) positively correlated with the severity of post-concussion symptoms. NFL, tau and Interleukins (IL-1 Ra and IL-6) have the potential to determine return to play. CONCLUSION: Serum biomarker measurement is an objective tool that aids in early diagnosis and predicts the severity and prognosis of injury.

Objective This study was aimed to compare comparative efficacy of transsphenoidal endonasal endoscopic and microscopic pituitary surgery at single center of a developing country. Methods This study included 198 patients in which 50 patients were studied prospectively and 148 patients were studied retrospectively, diagnosed with pituitary adenoma who presented to neurosurgery department at Sawai Man Singh hospital in Jaipur, India, and were operated via transsphenoidal route between 2013 and 2018. Patients' records were reviewed and relevant clinical and surgical data were collected. Patients were divided into two groups based on the surgical procedure performed, endoscopic endonasal transsphenoid approach (group 1) and microscopic transsphenoidal approach (group 2). Outcomes, in terms of efficacy and the resulting complications of each procedure were compared and analyzed. Results A total of 198 patients with pituitary adenoma were operated during the study period. Among them, 119 (60.1%) patients were operated by endoscopic and 79 (39.9%) patients were operated by microscopic transsphenoidal approach. In endoscopic group, intraoperative cerebrospinal fluid (CSF) leak was present in 39 patients (32.77%) and 23 (29.11%) in microscopic group. Complete tumor removal was achieved in 69.75% in endoscopic and 48.13% in microscopic group ( p = 0.004). Endocrine control was achieved in 78.94% (30 out of 38) in endoscopic and 68.18% (15 out of 22 patients) in microscopic group. Conclusion The transsphenoidal approaches for resection of pituitary adenoma, both endoscopic and microscopic approach, are minimally invasive and effective for disease control. Both the approaches lead to similar endocrine control, visual symptoms, complications, and long-term outcome. Therefore, the selection of the final approach should be individualized, ultimately depending on the surgeons' comfort, experience, and familiarity with the particular technique.
RESUMEN
PURPOSE: This systematic review was done with the aim to answer these three questions: 1) Is there any change in diffusion metrics in MRI-DTI sequences after mild traumatic brain injury in paediatric and young population?, 2) Is there any correlation of these changes in diffusion metrics with severity of post concussion symptoms?, 3) Is the change in diffusion metrics predictive of neurocognitive function or neurological recovery? MATERIAL AND METHODS: Eligibility criteria- Mild TBI patients upto 22 years of age, MRI- DTI sequence done post injury, Outcome measurement with follow up at least for onemonth and articles published in English language only. Data sources- PubMed, EMBASE, CINAHL, Scopus and Cochrane RESULTS: Some studies show increased FA and some studies show decrease FA and few showed no change in white matter microstructure in mTBI patients and this depends on the duration of injury. Prediction of PCSs severity on the basis of changes in white matter microstructure showed inconsistent results. Radiological recovery in contrast to clinical recovery, is often delayed ranging from 6 months to 2-3 years. But change in diffusion metrics after mTBI is not definite predictive of neurocognitive outcomes. CONCLUSION: Large, properly designed, multicentric studies with appropriate extracranial or orthopedic control and long follow up are needed to establish the use of DTIin mTBI for predicting behavioral outcome.

Spontaneous onset extradural hematoma (EDH) is a very rare entity and has been seen mostly to be associated with adjacent infective pathologies, dural vascular malformations, extradural metastasis, or coagulopathies. We report a series of two such cases and review the literature. One case presented with spontaneous EDH that was managed conservatively and was diagnosed to have chronic kidney disease later; the other had deranged coagulation profile and liver function secondary to drug induced hepatitis and was operated. Both patients were discharged in a stable condition and were improving on follow up.

Background Traumatic posterior fossa hematoma is a rare entity. Traumatic posterior fossa hematomas are associated with considerable morbidity and mortality and their surgical management remained controversial. Methods From August 2011 to August 2017, approximately 5,100 patients with head injury were managed. Authors reviewed clinical and radiological findings, management criteria, and outcome of posterior fossa hematoma in 21 patients. Results Out of 21 cases, 13 survived with our management. The Glasgow Coma Scale (GCS) on admission was higher in favorable group than in poor outcome group. Factors associated with Glasgow Outcome Scale in two groups were status of fourth ventricle, basal cisterns, subarachnoid hemorrhage (SAH), hematoma volume, and their location (hemispheric or midline). Similarly, associated supratentorial lesions, age, gender, lesions in other parts of body, and timing from injury to reporting to hospital were taken into consideration. Conclusion The factors correlated with patient outcome were age, sex, mode of injury, GCS at admission, associated intracranial hematomas, associated SAH, hematoma volume, hematoma location, basal cisterns, status of fourth ventricle, and associated multiple injuries on other body parts. It is hereby concluded that timely surgical intervention should be employed whenever indicated without delay. Posterior fossa hematomas were rarely observed in the pediatric age group.
RESUMEN
Spinal arachnoid cysts are uncommon benign lesions of spine axis and most commonly present as compressive myelopathy. Intramedullary arachnoid cyst is uncommonly seen, hence, not much discussed in literature. Due to rarity of this entity, many questions are yet to be answered and should be addressed properly, particularly related to etiopathogenesis, accustomed course, behavior, differential diagnosis, and the best treatment modality. We report the clinicopathological profile of thoracic intramedullary arachnoid cysts in two adult patients, and present a detailed review of available literature on the spinal intramedullary arachnoid cyst. Most of the literature concerning with intramedullary arachnoid cysts are in the form of case reports from pediatrics population. As far to the best of our knowledge, only a few cases excluding our two were found in both pediatrics and adult population.
RESUMEN
INTRODUCTION: Cognitive impairment is one of the most important culprit influencing the long-term neurological outcome commonlyobserved in TBI survivors. AIMS: To examine the performance of patients with Mild and Moderate traumatic brain injury (TBI) on the Montreal Cognitive Assessment (MoCA) using as a screening tool. RESULTS: Total 228 (127 Mild TBI & 101 Moderate TBI) patients were recruited in this study. Results showed that patients with moderate TBI had lower score on the MoCA as compared to patients with mild TBI (p Value = 0.031). This difference was observed statistically significant among mild and moderate TBI for the cube copy (p = 0.039) and clock (p = 0.017) i.e. visuospatial/executive function, Digit span test (p value = 0.040) i.e. concentration and recall memory (p = 0.04). MoCA Score were higher for patients with higher GCS score at admission. Education status was also correlated with MoCA scores; those patients with higher level of education had significant association with higher MoCA scores (p value = 0.012). This study showed that age and gender were insignificant variables to determine cognitive function. CONCLUSION: Assessment of cognitive impairment should be considered as a mandatory protocol while evaluating post TBI patients, even in cases of mild TBI. Visuospatial/Executive function, memory and attention are the most commonly impaired cognitive functions in patients of TBI, and these are the main domain of cognition which differentiates mild impairment from moderate impairment. This information enables us and provides insight to our experience to predict the burdens of problem and plan to develop post TBI dedicated rehabilitating programme.

We report two cases of gastrointestinal perforation by ventriculoperitoneal (VP) shunts and review the literature on the topic. The time interval between shunt surgery and detection of bowel perforation is minimum in infants and increases with age. Sigmoid and transverse colon followed by stomach are the most frequent sites of gastrointestinal perforations by VP shunts.
RESUMEN
Dissecting anterior inferior cerebellar artery (AICA) aneurysms are extremely rare, and only nine cases are reported till date. We are reporting a case of ruptured dissecting distal AICA aneurysm with spontaneous resolution; first of its kind in the indexed literature.
RESUMEN
Central nervous system (CNS) tuberculosis commonly manifests as tubercular meningitis. CNS tuberculomas are more common intracranially and less frequently involve the spinal cord. Combination of intramedullary with intracranial tuberculomas is extremely rare. We report a case of concurrent occurrence of intramedullary tuberculoma with multiple intracranial tuberculomas in a young 16-year-old boy, who presented with two weeks history of paresthesias and weakness of the lower limbs and diminution of vision in left eye, who had been treated for pulmonary tuberculosis. Magnetic resonance imaging (MRI) spine showed a well-circumscribed lesion opposite L1, which was diagnosed as intramedullary tuberculoma. As for vision complaint, on cranial imaging, he was found to have multiple round contrast enhancing lesions, which were diagnosed as intracranial tuberculomas based on their typical MRI findings. He had complete recovery with conventional treatment of anti-tubercular therapy and steroids, without any surgical intervention. We suggest that MRI of the brain should be performed in all case of intramedullary spinal tuberculoma because of the possible presence of early asymptomatic/mild symptomatic intra-cranial tuberculomas.
RESUMEN
Solitary fibrous tumor (SFT) is a rare neoplasm that is thought to be of mesenchymal origin. Occurrence of such a tumor in the orbit is rare, more so in its malignant form. Histopathologically, it can mimic several other tumors of the orbit and can be differentiated by CD34 positivity. We report a case of malignant transformation of an SFT of the orbit that recurred after 15 years. The differentiating histopathological features with special stress on the importance of CD34 positivity and principles of management are outlined. The need for long-term follow-up to detect recurrence and malignancy is stressed.
RESUMEN
Primary non-Hodgkin's lymphoma (NHL) of the cranium with extra- and intracranial extension without systemic or skeletal manifestation in a non-immunocompromised patient is extremely rare. These lesions are most of the time misdiagnosed because they mimic other conditions like meningioma. Here, we report a case presented with huge bulky scalp mass which on magnetic resonance imaging (MRI) brain showed involvement of scalp, cranial vault, meninges, and the brain parenchyma, mimicking a meningioma. After gross total resection, biopsy and CD marker study revealed primary non-Hodgkin's diffuse large B-cell lymphoma (DLBCL). Malignant NHL should be considered in differential diagnosis of bulky scalp mass lesion.
RESUMEN
Ganglioglioma of the conus region is quite rare with only 12 reported cases. Ganglioglioma shares biologic features with neurofibromatosis leading to suggestions that the co-existence of the two diseases may be more than coincidental. We report a case of ganglioglioma of the conus medullaris in a patient of neurofibromatosis and explore the possible association of the two diseases.
RESUMEN
Burr hole evacuation of chronic subdural hematoma (SDH) with or without drainage system is the most common surgical method among various techniques. There are various complications of burr hole drainage evacuation of chronic SDH, but there is no case report regarding impaction and prolapse of brain parenchyma through burr hole as a complication. Herewith, we are reporting a case of bilateral chronic SDH with prolapse of brain parenchyma through burr holes. Magnetic resonance imaging (MRI) of brain showed a characteristic look and we named it "Tiger hide appearance". We failed to find such characteristic appearance in MRI brain on reviewing the available literature.
RESUMEN
Traumatic carotid-cavernous fistula (TCCF) is a direct communication between cavernous portion of the internal carotid artery (ICA) and cavernous sinus due to tear in ICA. Most of the cases are treated by endovascular embolization. Spontaneous resolution of high-flow TCCFs is extremely rare. We report a case of posttraumatic, direct, high-flow carotid cavernous fistula (Barrow type A) that resolved spontaneously after cerebral angiography.
