Supratentorial extra-ventricular ependymoma as a mass lesion in a child: report and literature review.

Supratentorial extra-ventricular ependymoma (SEE) are extremely rare in pediatric population and have varied presentation based on size, location, epicentre and compression on neurovascular structure. The authors report a 7-year-old girl presenting with seizure, who had a lobar SEE on MRI scan, successfully treated by microsurgical resection and adjuvant therapy.

Correction of pediatric cervical kyphosis: our experience and systematic-literature review.

BACKGROUND: Pediatric cervical kyphosis is a distinct entity with diverse etiology (congenital, syndromic, traumatic, metabolic or neoplastic). Surgical correction in pediatric population is challenging due to their growing spine and low blood volume. PURPOSE: To analyse their presentation, surgical techniques and outcome of pediatric cervical kyphosis and systematically review the pertinent literature. DESIGN: Retrospective study. PATIENT SAMPLE: 16 patients aged ≤ 18 years who underwent correction for cervical kyphosis between 2009 and 2021. OUTCOME MEASURES: Nurick's grading, mJOA score and Global cobb's angle. METHODS: Clinical parameters (Nurick grading and mJOA score) were noted from database on admission and on follow-up at 6 months. Radiological parameters of assessment included Global Cobb's angle. The C2-C7 Cobb angle was the angle of C2 vertebra lower end plate and C7 vertebra lower end plate. For C1-2 kyphosis, anterior border of C1 and anterior border of C2 angle was taken. Radiographic parameters were studied on CT and radiographs of cervical spine to assess for stability, the degree of deformity correction and fusion status at 6 months follow-up. RESULTS: 16 patients with mean age of 14.2 ± 3 years (9 syndromic, 4 post-traumatic, 2 metabolic and 1 post-laminectomy). All underwent surgical correction, 6 underwent Antero-posterior spinal fusion, 6 underwent Posterior spinal fusion and 4 underwent Anterior spinal fusion. There was significant clinical improvement postoperatively with-Nurick grade (pre vs. post: 2.8 vs. 1.8, p = 0.004), mJOA score (pre vs. post: 11.3 vs. 14, p = 0.003). There was significant deformity correction of Cobb's angle from 40.7 ± 26.5° to 14.9 ± 10° (p = 0.001). Early complications included intraoperative hemodynamic instability (3) and wound complication (1). Mean follow-up was 76.9 ± 59.3 months. CONCLUSION: Pediatric cervical kyphosis is a debilitating condition which are managed surgically. Approach has to be individualized to the pathology and good results can be achieved. Patients should be screened for syndromic association and followed-up regularly.

Cervical kyphosis correction in Marfan syndrome: our experience and literature review.

BACKGROUND: Spinal deformities are common in Marfan syndrome (MFS). They usually involve the thoraco-lumbar spine but rarely involves the cervical spine. Kyphosis is the common spine deformity of the cervical spine and mandates surgical correction as they are at risk of neurological deterioration since they are refractory to conservative management. Few studies of surgical correction of spine deformity included cervical deformity. OBJECTIVES: To analyze the challenges faced during surgery, clinical and radiological outcome, and complications following surgical correction for cervical kyphosis in Marfan syndrome. METHODS: We identified that 5 patients with a diagnosis of MFS with cervical kyphosis who underwent fusion surgery between the years 2010 and 2022 were reviewed, retrospectively. We analyzed the demographic details, radiological parameters, operative variables (blood loss and nuances), perioperative complications, length of stay, clinical and radiological outcome, and complications following fusion surgery for cervical kyphosis in MFS. RESULTS: The mean age of patients was 16.6 ± 4.72 years (range, 12-23 years). The average kyphotic vertebra involved is 3 ± 0.7 bodies (range 2-4) with 2 patients with thoracic deformity. All patients underwent surgical deformity correction. All patients improved clinically with Nurick grade (pre vs. post: 3.4 vs. 2.2) and mJOA (pre vs. post: 8.2 vs. 12.6). There was significant deformity correction from 37.48° to 9.1°. Mean blood loss encountered was 900 ± 173.2 ml. Perioperative complications: wound complication with CSF leak (1). Late complications: ventilator dependence (1) and junctional kyphosis (1). Mean length of hospital stay was 103 ± 178.9 days. All patients were doing symptomatically better after mean follow-up of 58 ± 28.32 months. One patient is bedridden and hospitalized. CONCLUSION: Cervical kyphosis is a rare spine deformity in patients with MFS, and they usually present with neurological deterioration mandating surgical correction. Multidisciplinary approach (pediatrics, genetics and cardiology) is required for systematic evaluation of these patients. They should be evaluated with necessary imaging to rule out associated spinal deformity (atlanto-axial subluxation, scoliosis, and intraspinal pathology like ductal ectasia). Our results suggest better surgical outcome in terms of low operative complications with neurologic improvement in MFS patients. These patients require regular follow-up to identify late complications (instrument failure, non-union, and pseudarthrosis).

Multiple spinal extradural arachnoid cysts presenting as compressive myelopathy in a teenager: case report and literature review with special emphasis on postoperative spine deformity in the current minimally invasive era.

INTRODUCTION: Multiple synchronous spinal extradural arachnoid cysts are extremely rare in children and can lead to cord compression and disability. Multiple spinal extradural arachnoid cysts (SEDACs) in children with immature and growing spine need to be studied separately from multiple SEDACs in adults with mature and fully grown spine because of multiple surgical limitations in children (blood loss, surgery duration, long-term spinal stability after long segment exposure, etc.). MATERIAL AND METHODS: We planned a non-systematic literature review of similar cases described in literature to analyse the pattern of presentation, management, and outcome of this surgically curable disease. RESULTS: A total of 28 cases of paediatric multiple SEDACs in the age range of 5 months to 17 years and mean age of 11.54 years were analysed. Exposure was achieved by laminectomy in 9, laminoplastic laminotomy in 13, laminectomy in first surgery followed by laminoplasty in second surgery (re-exploration) in 1, hemilaminectomy in 2, and technique "not reported" in 3 children. Complete/near-complete recovery was seen in 27 (96.42%) children. Postoperative spine deformity was reported in 7 (25%) children and was progressive in 2 children during serial follow-up. CONCLUSIONS: Symptomatic multiple synchronous SEDACs in children is a rare surgically curable condition. Sincere attempt to find out a dural defect in all cysts is a very important step in multiple SEDAC surgery. Total cyst wall excision with closure of all dural defects is the gold standard treatment for symptomatic cases. Laminoplasty is preferred for excision of multiple SEDACs in children to prevent postoperative spine deformity during long-term follow-up. Long serial follow-up for postoperative spine deformity is necessary.

Non-chordomatous clival bony tumors: A rare experience and systematic literature review.

BACKGROUND: Non-chordomatous bony tumors of the clivus are extremely rare. Site, extent, and aggressiveness of tumor limits the extent of resection. It poses challenge to the neurosurgeons due to the complexity of anatomy. There is paucity of literature exclusively on non-chordomatous bone tumors of the clivus in young adults. OBJECTIVES: To analyze the clinical presentation, imaging findings, surgical approach, complications, and outcome of primary clival bony tumors in young adults. METHODS: We retrospectively reviewed children and young adults with primary clival bony tumors excluding chordoma who underwent surgical resection between years 2010 and 2023 in our center. We analyzed the demographic details, imaging findings, operative variables, perioperative complications, length of stay, complications, and outcome at latest follow-up. RESULTS: The mean age was 17.5 ± 1.73 years (range 16 to 19 years). Headache was the presenting complaint in all four patients (100%). The mean duration of symptom was 7.25 ± 3.2 months (range 5 to 12 months). The tumor was localized in clivus in all four patients (100%). The mean length of stay in hospital was 30.5 ± 13.48 days (range 11 to 40 days). All patients underwent surgical treatment. Surgical approaches used were anterior approach in four patients (100%). Gross total excision was performed in one patient (25%), sub-total excision was performed in two patients (50%), and tumor decompression was performed in one patient (25%). Of these, three were designated as having benign tumors and one had a malignant tumor. There was no perioperative mortality. There was one mortality (25%) on 2 months follow-up due to tumor progression. Three patients (75%) had improved symptomatically at latest follow-up. Two patients (50%) received adjuvant chemoradiotherapy. The mean follow-up was 38 ± 39.29 months (range 2 to 72 months). CONCLUSION: Non-chordomatous bony tumors of the clivus are rare and often underestimated. Surgery is the treatment of choice. Tumor consistency and adhesion to critical neurovascular structures precludes gross total resection. Various approaches are in the armamentarium. Approach to be decided based on the expertise of the neurosurgeon to achieve safe maximal resection. Multidisciplinary approach is mandatory for streamlined management. Adjuvant therapy is decided based on the residual tumor following surgery.

Role of Interleukin-6 in Prediction of Early Complications After Minimally Invasive Oesophagectomy-a Pilot Study.

Infectious complications following oesophagectomy are associated with significant morbidity. Early prediction of these complications may mitigate significant morbidity and mortality. Patients undergoing minimally invasive oesophagectomy for carcinoma oesophagus between January 2019 and June 2020 were included in the study. All patients underwent standard preoperative investigations and preparation. Post-operative complications including infectious complications were recorded. Association of post-operative serum interleukin-6 (IL-6) levels with post-operative complications were analysed. A total of twenty-two participants were included in the study (median age; 51 years, 13 (%) male). The tumour site was middle 1/3rd of oesophagus in 13 (59.1%), lower 1/3rd of oesophagus in 9 (40.9%). The tumour histology was squamous cell carcinoma in all patients. Eight (36.4 %) patients developed major complications and five of them developed anastomotic leak. IL-6 levels were significantly higher on POD 3 in patients who developed major complications (p = 0.009) and anastomotic leak (p = 0.031). At receiver operating characteristic curve (ROC curve) analysis, an IL-6 cut-off level of 36.4 pg/ml on POD 3 yielded a sensitivity of 87% and a specificity of 79% for the prediction of major complication and cut-off level of 44.3 pg/ml on POD 3 yielded a sensitivity of 80% and a specificity of 82% for the prediction of anastomotic leak. A high post-operative IL-6 level helps in the prediction of major complications and cervical oesophagogastric anastomotic leak.

Serous cystadenoma of head pancreas masquerading as pancreatic neuroendocrine tumor: Treated by Whipple's pancreaticoduodenectomy.

Serous cystadenoma (SCA) is the most common cystic neoplasm of the pancreas. Serous cystadenoma is best diagnosed by imaging with computed tomography scan. Fine-needle aspiration cytology is required for definitive preoperative diagnosis. Serous cystadenoma may be sometime difficult to differentiate from pancreatic neuroendocrine tumor (PNET) in the preoperative stage. Differentiating the two entities are important for proper treatment strategy. Serous cystadenoma may be managed in expectant observation. However, all PNETs will need surgical treatment including pancreaticoduodenectomy (PD). Here, we present a rare presentation of serous cystadenoma head of pancreas masquerading as PNET with local compressive symptoms for which Whipple's PD was done successfully.

Intracranial myeloid sarcoma as the first presentation of acute myeloid leukemia and literature review.

INTRODUCTION: Intracranial myeloid sarcoma is a rare extramedullary presentation of acute myeloid leukemia (AML). It can involve the meninges and ependyma presenting as extra-axial mass lesion. Rarely, it can also invade the brain parenchyma. It is commonly seen in children. It is usually misdiagnosed due to its close resemblance to other intracranial tumors (meningioma, metastasis, Ewing's sarcomas, and lymphoma). These are underdiagnosed if they precede the diagnosis of leukemia. CASE REPORT: A 7-year-old boy with isolated intracranial myeloid sarcoma who presented with raised intracranial pressure (ICP) which was successfully managed by surgical excision. CONCLUSION: Isolated intracranial myeloid sarcoma is a rare presentation of AML. Leukemia can be diagnosed early during the postoperative period and can be started on therapy timely. These patients requires regular follow-ups (clinical, laboratory and radiological) to detect relapses early.

Reverse Cortical Sign in Lumbar Burst Fracture.

"Reverse cortical sign" is a rare entity described in lumbar burst fracture that corresponds to the fracture fragment of the posterior wall of vertebral body, which has rotated 180 degrees with the cortical surface facing anteriorly and the cancellous surface facing posteriorly in the canal. Identifying this sign is crucial in deciding the line of management as it is a contraindication for ligamentotaxis. The advent of computed tomography scans with axial and sagittal reconstruction has allowed us to better describe these rare entities. We present a lumbar burst fracture with a reverse cortical sign describing its appearance in axial computed tomography scans, sagittal reconstruction, and magnetic resonance imaging.

Successful management of impaled ice-pick stab injury of the suprarenal aorta - lessons learnt.

Penetrating injury of the aorta is rare and lethal. The reported mortality rate is very high. Few patients survive and present to the hospital. Some of these injuries are salvageable if treated in a timely and aggressive manner. Here we present a case of penetrating injury of the aorta with impalement of the ice-pick, which was successfully managed with laparotomy and primary repair of the aortic injury after adequate resuscitation.

Periampullary Carcinoma in a 13-Year-Old With Microsatellite Instability Treated Successfully With Pancreaticoduodenectomy.

Periampullary carcinoma in adolescents is very rare and may be associated with hereditary syndromes. Pancreaticoduodenectomy (PD) in adolescents is rarely performed. The experience and results of pancreaticoduodenectomy in adolescents are not well reported. Here, we report a case of periampullary carcinoma, duodenal origin, signet ring type with microsatellite instability (MSI), in a 13-year-old male for which pancreaticoduodenectomy was successfully done.

Deodorant aerosol spray can in the rectum: a potential fire hazard during surgery.

Rectal foreign bodies are not uncommon and often pose a serious challenge to surgeons. In majority, the objects are inserted by self in children, psychiatric patients and for sexual gratification in adults. Various rectal foreign bodies have been reported. Deodorant aerosol spray can in the rectum has not been reported previously. Danger of aerosol dispenser can is the risk of fire and explosion. Especially during any surgical procedures to remove the foreign body using cautery or any energy devices. We report of a rare foreign body of deodorant aerosol spray can in the rectum in a young male patient, which was removed under general anaesthesia.
