Published: December 2020

Primary extradural spinal melanoma is a very rare lesion. Here, we report a thoracic extradural malignant melanoma in a 77-year-old male. MRI showed a dorsal spinal extradural tumour at the T6-T8 level. The tumour showed hyperintensity on T1W imaging and mixed hypointensity and hyperintensity on T2W imaging. Gadolinium-enhanced MRI showed high enhancement on the lesion. Information on imaging findings for extradural spinal melanoma appears very limited. We discuss the MRI findings from this case, which can be considered typical of extradural spinal melanoma and review the literature.

Pediatric spinal tumors include a variety of developmental lesions and uncommon neoplasms that differ significantly from those seen in adults. These conditions are underreported in the sub-Saharan medical literature. We present the case of a 10-year-old girl brought by her family to the University Teaching Hospital of Kinshasa in the Democratic Republic of Congo with progressive lower limb functional impairment.

Study Design: Systematic review.

Objective: In patients with extradural metastatic spine disease, we sought to systematically review the outcomes and complications of patients with intermediate Spinal Instability Neoplastic Score (SINS) lesions undergoing radiation therapy, percutaneous interventions, minimally invasive surgeries, or open spinal surgeries.

Methods: Following PRISMA guidelines for systematic reviews, MEDLINE, EMBASE, Web of Science, the Cochrane Database of Systematic Reviews and the Cochrane Center Register of Controlled Trials were queried for studies that reported on SINS intermediate patients who underwent: 1) radiotherapy, 2) percutaneous intervention, 3) minimally invasive, or 4) open surgery.

Introduction And Importance: Paragangliomas are rare neuroendocrine tumors, typically arising from extra-adrenal chromaffin cells. Primary intra-spinal paragangliomas are uncommon, and metastatic spinal paragangliomas without paraneoplastic symptoms are even rarer. This case highlights the diagnostic challenges posed by such rare tumors.

Endoscopic spinal surgery has gained increasing popularity over the past 10 years. Its muscle-preserving nature, reduction in postoperative pain, and lower complication rates have contributed to the growing number of surgeons adopting this technique year after year. This same progression has led to the application of the technique in oncological pathology, primarily for separation surgeries and biopsies of extradural lesions.

Background: Spinal epidural arachnoid cysts (SEACs) are rare, non-neoplastic pathologies that can cause compressive myelopathy. Preoperative identification of the exact fistula location is crucial for minimally invasive management.

Methods: This single-center retrospective study included 27 patients with SEACs who underwent "double-needle puncture myelography" to precisely localize the fistula before minimally invasive surgery.
