RESUMEN
INTRODUCTION: Subaxial cervical spine injuries (SCSI) can lead to disastrous consequences such as quadriplegia, with/without respiratory paralysis (RP) and hemodynamic instability (HDI). Till date, there is no literature available for reporting outcomes of SCSI patients specifically pertaining to those presenting with RP/HDI and ours is the first study to document the same. METHODS: Retrospective 6-year study from a tertiary trauma centre database including patients >/= 18 years of operated SCSI. Only patients with ASIA A grade with admission RP/HDI and unstable injuries (fractures, subluxations) were included. Patients with ASIA grade B and above, patients with non-osseous injuries (such as disc herniation, central cord syndrome etc.) were excluded. RESULTS: 24 cases were analysed. C5 and C6 levels were the commonest. Vertebral listhesis/subluxation was the predominant radiological finding. The mean age was 47.4 years (22-79 years) and all, except one were males. Fall from height and road traffic accident (RTA) were the most common mechanisms of injury. The most common surgery was anterior discectomy and fusion followed by corpectomy. The overall mortality rate was 22/24 (92)%. Cord edema and hemorrhage had significant association with survival. None of the grade A survivors with HDI/RP showed improvement. The mean FU duration was 18.5 months (range, 16.5-20.5 months). CONCLUSIONS: Subaxial ASIA A cervical spine injuries with pre-operative RP/HDI is an indicator for non-improvement. This is the first study documenting outcome in such patients. The mortality rate in these patients is very high and is an extremely poor prognostic factor for recovery. Hence, surgery in such patients need to be decided judiciously, especially in developing countries that has a significant financial impact on the family members.
RESUMEN
Background: Spinal eosinophilic granulomas (EG) are rare tumors, mostly reported in the pediatric age group. They constitute <1% of primary bone neoplasms, and cervical spine involvement is uncommon. Case Description: A 20-year-old male presented with neck pain for a 4-month duration. Six years previously, he had received six cycles of vinblastine for biopsy-proven histiocytosis of an axillary lymph node; this resulted in incomplete remission. Present magnetic resonance/computed tomography (CT) imaging revealed a lytic C2 body lesion with atlantoaxial instability. When the CT-guided biopsy was suggestive of EG, he was managed with definitive surgery and adjuvant radiotherapy. Conclusion: Cervical spine EG is rare in adults. CT-guided biopsy should confirm the diagnosis and should be followed by definitive surgery and adjuvant radiotherapy.
RESUMEN
BACKGROUND: Atypical teratoid/rhabdoid tumours (AT/RT) are uncommon but aggressive, malignant tumours in the paediatric age group. Presentation of concomitant supratentorial and infratentorial lesions in an infant is extremely rare. We discuss an infant diagnosed with such lesions. Systematic PubMed search was conducted using keywords 'atypical teratoid /rhabdoid tumor', 'paediatric' and 'multifocal'. Reports were included for patients younger than 18 years with two or more lesions. The search yielded additional five cases and were tabulated. Age, sex, location, treatment given and survival/outcome were noted. CASE REPORT: A 10-month-old child presented with complaints of drowsiness and intractable vomiting. Imaging showed multifocal supra- and infratentorial lesions with obstructive hydrocephalus. The child underwent ventriculoperitoneal shunt followed by surgical removal of the posterior fossa lesion. Histopathological features were consistent with AT/RT. CONCLUSIONS: Multifocal AT/RT are very rare. The impact of multifocality in the outcome is not known as very few reports are available. Newer targeted therapies may offer insight in improving outcomes in the future.

Background: Traumatic basal ganglia hematomas (TBGH) are rare entities. They are situated in the deep cerebral parenchyma and have also been termed as intermediate coup contusions. Available literature is sparse with regards to the characteristics and prognosis of TBGH. We aim to share our experience in the management, outcomes, and prognostic factors of TBGH. Methods: A 4-year retrospective study which included all cases of TBGH, except dot contusions (<2 mL) and those with coagulopathies. Admission variables were correlated with Glasgow Outcome Scale score at discharge and 12 months. Results: Thirty-two patients were analyzed. The mean age was 39.2 years. Two-thirds were due to road traffic accidents. Around 60% were severe head injuries. The mean Glasgow coma scale (GCS) score at presentation was 8.5. Twenty patients had moderate-to-severe hemiparesis. The mean hematoma volume was 18.1 mL. Associated traumatic intracranial lesions were seen in 28 cases. Only 7 patients (22%) underwent surgery. The mean follow-up was 17.4 months (range 14-34 months). The mortality rate was 12.5% (n = 4). Among the survivors, only 39% (n = 11) had good outcomes at discharge which showed modest improvement to 54% (n = 15) at 12 months. Conclusion: Our study noted that poor admission GCS scores, poor motor response, presence of significant hemiparesis, and larger hematoma volumes (>20 mL) correlated with poor outcomes at 12 months. The overall outcomes have been mostly unfavorable as observed in majority of studies due to deeper location of these hematomas, high proportion of severe head injuries, and high proportion of residual weakness in survivors.
RESUMEN
BACKGROUND: The commonly observed complications after cranioplasty include infections, intracranial hemorrhage, and seizures. The timing of cranioplasty after decompressive craniectomy (DC) is still under debate, with literature available for both early and delayed cranioplasties. The objectives of this study were to note the overall complication rates and more specifically compare complications between 2 different time intervals. METHODS: This was a 24-month, single-center, prospective study. Since timing is the most debated variable, the study cohort was divided into 2 groups (≤8 weeks and >8 weeks). Furthermore, other variables such as age, gender, etiology of DC, neurologic condition, and blood loss were correlated with complications. RESULTS: A total of 104 cases were analyzed. Two thirds were traumatic etiology. The mean and median DC-cranioplasty intervals were 11.3 weeks (range 4-52 weeks) and 9 weeks, respectively. Seven complications (6.7%) were observed in 6 patients. There was no statistical difference observed between any of the variables and complications. CONCLUSIONS: We observed that performing cranioplasty within 8 weeks of the initial DC surgery is safe and noninferior to cranioplasty performed after 8 weeks. Therefore if the general condition of the patient is satisfactory, we are of the opinion that an interval of 6-8 weeks from the primary DC is safe and a reasonable time frame for performing cranioplasty.

Majority of C2-C3 vertebral dislocations occur as in combination with bilateral pars fractures, also known as Hangman's fractures. Isolated C2-C3 facet dislocation without any associated C2 fracture is a very rare injury. One such case has been presented in this report. A 29-year male was involved in a road traffic accident (RTA) after which he developed midline neck pain. Following a minor neck manipulation at a hair salon 15 days after the RTA, his neck pain worsened and he developed quadriparesis. Imaging at the time of admission showed bilateral high-grade C2-C3 facet dislocations without any associated fracture of C2 vertebra. Due to non-reduction of the dislocation with skeletal traction, surgery was contemplated. Intraoperatively, the C2-C3 joint spaces were opened but only partial reduction could be achieved. Complete reduction was achieved only after opening of the C1-C2 joints was performed. Later, C2-C4 screw-rod constructs were placed. Patient achieved good outcome with resolution of symptoms. This report concludes that, in cases of delayed presentation of irreducible C2-C3 bilateral facet dislocations and non-reducibility by skeletal traction, opening of the C1-2 joints may need to be performed in addition to the C2-C3 joint spaces, in order to achieve complete reduction.

OBJECTIVE: Melanocytes are neural crest derivatives. Intracranial meningeal melanocytomas (MM) are rare tumors and the available literature is sparse for these neoplasms. This review aims to provide a detailed and comprehensive literature review of these tumors. METHODS: By searching online databases, a literature review was performed to include and analyze all cases of cranial MM reported to date. PRISMA guidelines were followed for the review process. RESULTS: A total of 109 cases were analyzed. The male/female ratio was 1.2:1. The mean age was 40.3 years. The mean duration of symptoms was 23.9 months (range, 2 days-15 years). Cerebellopontine (CP) angle, suprasellar, and Meckel cave were the most common locations. Sixty-four patients (58%) underwent gross total resection (GTR). Twenty-eight patients (26%) received some form of adjuvant radiation. There were 29 recurrences (26%) and mean time to recurrence was 50.2 months. The recurrence rates (RRs) for GTR and subtotal resection were 20% and 42%, respectively. The extent of resection (subtotal resection) and tumor locations (CP angle and Meckel cave) were significantly associated with higher RR. Six patients (6.5%) had higher-grade transformations. CONCLUSIONS: Complete surgical resection is the ideal treatment and adjuvant radiation is to be considered for residual/recurrent tumors. Adjuvant radiotherapy may also be prescribed despite GTR, in locations with higher RR such as CP angle and Meckel cave. Because of higher-grade transformations and delayed recurrences, long-term follow-up is required.

BACKGROUND: Brain edema is a common phenomenon after traumatic brain injury (TBI) resulting in increased intracranial pressure and subsequent neurological deterioration. Experimental studies have proven that brain edema is biphasic (cytotoxic followed by vasogenic). Till date, all studies, including the corticosteroid randomization after significant head injury (HI) trial, have used high-dose steroids in the acute period during which the edema is essentially cytotoxic in nature. No clinical data exist pertaining to delayed cerebral edema (vasogenic) and steroids. METHODS: Patients who had received steroids for delayed cerebral edema after TBI were retrospectively analyzed over a 2-year period. Steroid dose, timing of steroid prescription, time to improvement of symptoms, and complications were noted. RESULTS: There were six males and three females. Mean age was 41.1 years. There were no severe HI cases. All subjects had cerebral contusions on imaging. Dexamethasone was the preferred steroid starting with 12 mg/day and tapered in 5-7 days. The mean interval to steroid administration after trauma was 7 days. The mean duration of steroid prescription was 6.3 days. All patients had complete symptomatic improvement. The mean time to symptom resolution was 3.8 days. No patients experienced any complications pertinent to steroid usage. CONCLUSION: This is the first study to document efficacy of steroids for delayed cerebral edema after TBI, at least in mild/moderate head injuries. The timing of steroid usage and dose of steroids is key aspects that might determine its efficacy in TBI which was the drawbacks of the previous studies. Future prospective trials with the above factors in consideration may confirm/refute above findings.
RESUMEN
BACKGROUND: Achieving optimal brain relaxation is paramount in aneurysm surgery. Despite proper positioning and the use of newer anesthetic drugs and the administration of decongestants, it is often not possible to achieve satisfactory relaxation, which can lead to neurological deficits owing to excessive brain retraction. The present study aimed to provide detailed surgical notes regarding the novel technique of temporal horn tapping for intraoperative ventriculostomy. METHODS: The hospital records of anterior circulation aneurysm surgery performed during the previous 5 years were retrieved. Only those cases in which we had used temporal horn tapping were included. Ventriculostomy was performed only in those cases in which the brain was tense despite the administration of decongestants. A small corticectomy was performed over the middle temporal gyrus and deepened to access the temporal horn. RESULTS: This technique was used in 84 surgical cases. The mean patient age was 52.8 years. The male/female ratio was 1:1.4. Anterior communicating artery aneurysms were the most common. Adequate brain relaxation was satisfactorily achieved in all cases. Two patients had developed a small temporal hematoma attributable to the temporal corticectomy, both managed conservatively. CONCLUSIONS: We believe that this new trajectory through the middle temporal gyrus to access the temporal horn is very safe because of the lack of proximity to any blood vessel or critical structures. We recommend the use of this technique during pterional approaches for acute aneurysmal surgery in the tight, bulging brain to achieve relaxation and avoid secondary complications such as retraction contusions and resultant cerebral edema.

BACKGROUND: Spontaneous intracerebral hemorrhage carries a poor prognosis with a 30-day mortality rate of 35%-52%. There is no standardized surgical technique for treatment of spontaneous intracerebral hemorrhage. While minimally invasive techniques are popular, there has been renewed interest in decompressive craniectomy (DC). We compared surgical and functional outcomes of standard craniotomy and DC, both with hematoma evacuation, in the surgical treatment of supratentorial spontaneous intracerebral hemorrhage. METHODS: This 4-year retrospective study compared outcomes of 2 surgical techniques: standard craniotomy in group A (n = 78) and DC in group B (n = 54). To minimize bias in case selection, propensity matching was performed to match preoperative Glasgow Coma Scale score and hematoma volume (group C). RESULTS: Hematoma evacuation was performed in 132 patients. Mean age of patients was 53.3 years, 50.5 years, and 52.06 years in groups A, B, and C, respectively. Median preoperative Glasgow Coma Scale score was 9, 7, and 8 (P = 0.01; P = 0.45), and mean hematoma volume was 46.21 mL, 50.91 mL, and 49.90 mL. Overall mortality was 26.5%; 62.9% (n = 22) of deaths were in group A, and 37.1% (n = 13) were in group B (P = 0.69). Median modified Rankin Scale score was similar in both groups, both at discharge and at 3 months. After determining propensity scores, mortality and outcomes of matched groups remained similar. CONCLUSIONS: DC with hematoma evacuation does not appear to provide a significant advantage over standard craniotomy with regard to functional outcomes and mortality. DC may overcome the need for subsequent surgery in accommodating postoperative mass effect in residual bleeds and rebleeds but is associated with greater blood loss and longer operative duration.

INTRODUCTION: Although cranioplasty (CP) is a straightforward procedure, it may result in a significant number of complications. These include infections, seizures, intracranial hematomas, and others. Many reports have stated that early CP is associated with higher complications; however, more recent articles have contradicted this opinion. We intend to share our experience and results on outcomes of CP from our university hospital. MATERIALS AND METHODS: This is a 3-year retrospective analysis of patients undergoing CP. Demographic profile, etiology of decompressive craniectomy (DC), DC-CP interval, operative details, complications, and follow-up data were analyzed. Correlation of complications with timing of CP and other factors was studied to look for statistical significance. RESULTS: A.total of 93 cases were analyzed. The majority were traumatic and ischemic stroke etiologies. There were eight open/compound head injuries (HIs). Eleven were bilateral and the rest unilateral cases. The mean and median CP interval were 8.5 weeks (range 4-28 weeks) and 8 weeks, respectively. All patients received 48 h to up to 5 days of postoperative antibiotics. Ten complications (10.7%) were noted (including one death). Poor Glasgow Outcome Scale at CP was the only statistically significant factor associated with higher complication rates. There was no statistical difference with respect to gender, CP material, and etiology; however, early CP had slightly fewer complications. CONCLUSION: Patients with poor neurological condition at the time of CP have a significantly higher risk of complications. Contrary to earlier reports, early CP (<12 weeks) was not associated with higher complications but rather fewer complications than delayed procedures. Adherence to a few simple steps may help reduce these complications.

PURPOSE: Spinal teratomas are rare tumours noted in adults and are commonly located in the thoracolumbar region. Currently, there appears to be a lack of clear consensus regarding the management and prognosis of these lesions. A comprehensive review along with an illustrative case managed at the author's institute has been presented. MATERIALS AND METHODS: Online database search was performed for literature review. RESULTS: A 26-year-old male presented with acute onset neurological deficits and imaging revealed features of conus teratoma. Subtotal resection was performed and patient achieved fair recovery. Including the present one, a total of 146 cases have been reported and were analysed. Mean age was 39.6 years (range 18-85 years) and males predominated. Limb weakness and backache were the commonest symptoms. Majority of the lesions were intramedullary and located in the thoracolumbar region. Complete resection (CR) was achieved in 45% of cases. All, except one, were mature teratomas. Recurrences were noted in nine (6.1%) cases. Outcome was good/excellent in 86 (60%) and fair/poor in 26 (18%) cases. The presence of pain, absence of limb weakness and CR were significantly associated with good outcomes. Furthermore, subtotal resection (STR) had significantly higher recurrence rates than CR. Four deaths (2.7%) were noted. CONCLUSIONS: Total surgical resection is the standard treatment and appears to be beneficial both in terms of outcomes and recurrences. Overall, recurrences are rare and may be managed by re-surgery. In addition, the present report is the eighth case of adult spinal teratoma with an acute onset presentation. These slides can be retrieved under Electronic Supplementary Material.

Purpose: Ossification of ligamentum flavum (OLF) is an infrequent cause of thoracic spinal stenosis, mostly found in Japan and other East Asian countries, and uncommon in other populations. The incidence of dural ossification (DO) ranges from 11-62%. None of the previously described imaging findings can accurately diagnose DO preoperatively. Author reports outcomes of 15 cases of thoracic OLF from an Indian tertiary center, propose a new MRI finding to preoperatively diagnose DO and compare the various differences between subjects with and without DO.Methods: Three and half year retrospective analysis. Demographic, clinico-radiological and operative details, and outcome were analyzed. Correlation between new MRI finding and intraoperative DO was also noted.Results: Fifteen patients (10 males, 5 females) with mean age of 51.3 years were analyzed. Ten (66.6%) cases had DO and the new MRI finding (T2 ring sign) had high correlation with intraoperative DO (sensitivity of 90%, specificity of 100%). The T2 hypointense rim corresponds to the calcified/ossified dura present around the thecal sac. Important clinico-radiological differences were observed in patients with and without DO. Canal diameter was uniformly <5 mm in Nurick grade V cases and <9 mm in those with DO. Mean follow-up duration was 19.5 months (range 4-45 months). All, except one, had significant symptomatic improvement, however, only two patients with DO attained Nurick grade I, perhaps because of the poor preoperative Nurick grade in those patients.Conclusions: Decompressive laminectomy (till the normal interlaminar space caudally and cranially) with complete removal of flavum including ossified dura, if possible, is the ideal treatment. Even after significant improvement, patients with DO may have mild residual myelopathy. Presence of DO, CSF leak and myelomalacia are neither related to wound problems nor clinical improvement. Higher preoperative Nurick grade was consistently associated with good clinical recovery. T2 ring sign is of benefit to surgeons in preoperative diagnosis of DO.

BACKGROUND: Central nervous system (CNS) melioidosis is rare. Clinical presentations depend on the region of endemicity. Despite treatment, neurologic disease has relatively high mortality rates. Less than 80 cases of CNS involvement have been reported. METHODS: A literature review was performed by searching online databases for melioidosis presenting as osteomyelitis or scalp/extra-axial abscess (OSEAA). In addition, 3 similar cases managed at my institute have been presented. RESULTS: Including this report of 3 cases, 20 additional cases have been reported. Of these, 12 cases (60%) were from India. The mean age of patients was 45.5 years (range, 29-74 years), and none were in the pediatric age group. Patients in the fifth to sixth decades were most frequently affected. The male to female ratio was 5.3:1. Eleven patients had predisposing factors. Fever, headache, and scalp swelling were the most common features. Five cases had history of previous melioid infection. Seven cases had systemic disease. Debridement was performed in 11 cases. The average intensive phase treatment duration was 4.6 weeks (range, 2-8 weeks) and 5.5 months (range, 3-12 months) for the maintenance phase. Mean follow-up duration was 13.5 months (range, 2 weeks-40 months). Two deaths (10%) were reported, and 1 case of residual frontal abscess had relapse. CONCLUSIONS: Cranial melioidosis presenting as OSEAA is associated with good outcome, in contrast with other neurologic presentations. Intensive phase for at least 2-3 weeks followed by maintenance phase for 3-6 months is the standard treatment, similar to other melioid presentations. A high degree of suspicion and accurate identification of the organism is crucial. Patients need to be monitored for recurrences, both clinically and radiologically.

PURPOSE: Orbital haemangiomas are common orbital tumors known for their slow growth. Acute presentation with haemorrhage into the tumor is a rare occurrence with only nine cases reported in literature. METHODS: The authors present a case of an elderly female with sudden onset of proptosis and swelling of the eye. There was a transient relief of symptoms with steroids with residual proptosis and ptosis at two weeks. Magnetic resonance imaging revealed an intraconal soft tissue mass in the inferolateral quadrant of the left orbit with a differential diagnosis of haemangioma with bleed or metastasis. RESULTS: Patient underwent a lateral orbitotomy and tumour excision and histopathological examination revealed a cavernous haemangioma with a thrombus. The patient had complete symptomatic recovery following surgery. CONCLUSION: Orbital haemangiomas presenting with haemorrhage is rare and should be differentiated from orbital venous anomalies prior to surgery.

INTRODUCTION: Congenital dermal sinuses (CDS) are uncommon lesions. They are most often noted in lumbosacral region and may lead to meningitis or spinal abscess. Intramedullary spinal cord abscess (IMSCA) due to CDS is rare and often co-exists with an inclusion tumor such as dermoid/epidermoid cyst. MATERIALS AND METHODS: Literature review was done to analyze all cases of pediatric IMSCA secondary to CDS by searching online databases starting from the oldest case reported. RESULTS: Only 50 cases have been reported and were analyzed. Mean age was 22.6 months (range 1 month-15 years). Fever, acute flaccid lower limb weakness, and urinary disturbances were the most common presenting features. Dermal sinus was commonest in lumbosacral region. Inclusion cysts were observed in 50% of cases. Staphylococcus aureus was the most the common organism. Mean follow-up duration was 18.2 months (range 1 week-156 months). Majority of the cases underwent multilevel laminectomy with myelotomy and drainage of abscess. Outcome was good-to-excellent in around 60% cases with four deaths. Presence of fever and limb weakness was significantly associated with poor outcomes. CONCLUSION: Intramedullary abscess secondary to CDS is very rare. Complete sinus tract excision, myelotomy and drainage of abscess, and decompression of co-existent inclusion cysts with prolonged antibiotic therapy remain the standard treatment. Approximately 60% cases achieve good outcomes. Fever and limb weakness portend poorer outcomes than those without.

Pilocytic astrocytomas (PAs) are seemingly innocuous and benign tumors. However, in recent times, many case series have documented high rates of hemorrhage in these neoplasms. We hereby provide a detailed analysis on hemorrhagic pilocytic astrocytomas (HPA) in adults and report one such case managed at our institute. In addition, salient differences between adult and pediatric hemorrhagic PA have been briefed. Hospital records were retrieved for our case. Literature review was conducted by searching online databases for the following keywords-pilocytic astrocytoma, hemorrhage, cranial, pediatric, and adults. A 22-year-old male with neurofibromatosis-1 presented with sudden onset headache and vomiting of 3-day duration. Imaging revealed a lobulated suprasellar lesion with obstructive hydrocephalus. Pterional transsylvian approach and subtotal resection were performed. Histopathology showed features of PA with bleed. Including current report, a total of 26 cases have been reported. Mean age was 37 years (21-75 years) and they are mostly found in the third decade. The male:female ratio was 2.1:1. Sudden headache with vomiting was the most common symptoms. Tumors were mostly located in cerebral hemispheres (n = 9/34.6%), hypothalamus/suprasellar region (n = 7/27%), and cerebellum (n = 6/23%). Two-thirds underwent gross total excision. There were two deaths and except one case, no recurrences were reported in those with available follow-ups. Hemorrhagic presentation of a PA is rare, although more commonly seen in adults and most commonly located in cerebral hemispheres. Maximal safe resection is the standard treatment and recurrences are rare.
