AI Article Synopsis
- Sacrococcygeal teratoma (SCT) is the most common type of teratoma in newborns and rarely extends into the spinal canal, with only a few cases reported.
- A study at one institution found three patients with SCT and intraspinal invasion, highlighting the importance of MRI for accurate diagnosis and surgical planning, and recommending a multidisciplinary team approach for management.
- Early diagnosis and exclusion of intraspinal extension are crucial for successful treatment, emphasizing the need for MRI if ultrasound suggests spinal invasion prior to surgery.
Article Abstract
Background: Sacrococcygeal teratoma (SCT) is the most common teratoma in neonates and arises from the coccyx. SCT with intraspinal invasion is extremely rare and only reported in a few cases.
Methods: 37 patients with SCT were identified at our institution between 2000 and 2018. Three of these patients had SCT with intraspinal extension. A literature review for intraspinal extension associated with SCT, including mode of diagnosis, presentation, surgical approach and neurological sequelae, between 1993 and 2018 was also conducted.
Results: The authors report three cases of infants who were antenatally and/or postnatally diagnosed with a sacrococcygeal teratoma extending into the spinal canal. We illustrate the challenges of accurate diagnosis and therapeutic management. Postnatal magnet resonance imaging (MRI) was the best method to define spinal anatomy and extension of the tumors prior to surgery. Management with a multidisciplinary team approach including neuroradiology, neurosurgery and general surgery was used in our two most recent patients. The literature review yielded 6 cases of SCT with intraspinal extension.
Conclusion: Intraspinal extension in SCT is rare but should be excluded at birth before attempting any resection. In case of positive spinal invasion on Ultrasonography (US), MRI is essential to plan for surgery and possible laminectomy to be able to perform a radical resection of this congenital tumor. We recommend this multidisciplinary approach.
Level Of Evidence: Level IV.

Article Synopsis
- Tumor invasion of the spinal canal occurs in about 15% of newly diagnosed neuroblastoma patients, prompting a need for effective treatment strategies that optimize survival while minimizing long-term effects.
- A study of 92 intermediate-risk neuroblastoma patients with intraspinal tumors revealed that nearly half were symptomatic at diagnosis, but most of them experienced complete resolution of symptoms following treatment, regardless of the initial severity or duration of their deficits.
- The findings suggest that while prompt diagnosis and chemotherapy are crucial, surgical options like laminectomy may not significantly improve motor symptoms, indicating that surgery should be reserved for cases with rapid worsening neurologic conditions.

Article Synopsis
- * A case study involving a 53-year-old woman highlighted a successful surgical strategy that combined laminectomy with video-assisted thoracoscopic surgery (VATS) to resect the tumour, initially discovered as a mediastinal mass on a chest X-ray.
- * Post-surgery complications included cerebrospinal fluid leakage, necessitating a second operation, but ultimately the patient recovered well, showcasing the need for a tailored, multidisciplinary approach in treating such tumours.

Meningiomas are tumors originating from arachnoid meningothelial cells. Occasionally, meningiomas are identified outside the central nervous system, and are referred to as extracranial meningiomas (EMs). The vast majority of EMs are an extension from an intracranial or intraspinal tumor.

Background: The capacity of presurgical image-defined risk factors (IDRFs) to predict secondary surgical outcomes in patients with neuroblastoma is controversial.
Methods: The International Neuroblastoma Surgical Report Form (INSRF) was employed to retrospectively collect the clinical data of 53 patients diagnosed with neuroblastoma at our hospital from April 2014 to April 2020. IDRFs were identified at the time of diagnosis and reassessed during the course of neoadjuvant chemotherapy.
