Spinal Schwannomas are benign nerve sheath tumors and the most common intradural extramedullary tumors of the spine, mainly occurring in the cervical and lumbar region. The location distinct from the spinal canal is very rare. We report a rare case of a 45year old male with Schwannoma in the dorsal paraspinal musculature. Complete surgical excision of the lesion was performed with clear margins and neuropathological analysis revealed a Schwannoma. There has been no recurrence after 6 months.

RATIONALE: Osteosarcoma is a rare neoplasm in the lumbar spine. Although osteosarcoma can arise in any portion of the skeleton, it very rarely arises in the spinal canal, which accounts for <0.1% of all cases of adult sarcomas. Here, we describe a case of osteosarcoma arising in the L4-5 spinal canal. PATIENT CONCERNS: The present report describes the case of a 55-year-old female patient with osteosarcoma of the L4-5 spinal canal. DIAGNOSES: The patient was initially diagnosed with lumbar spinal stenosis and underwent lumbar fusion at a local hospital...

Acinic cell carcinoma metastasizing to the spine is extremely rare. The authors present a case of acinic cell carcinoma of the parotid gland with subsequent lung and spinal metastases, treated with en bloc spondylectomy. A 41-year-old man presented with a left parotid mass. After being diagnosed with acinic cell carcinoma, he underwent a total parotidectomy. Imaging studies revealed a metastatic osteoblastic lesion in the T4 vertebral body and multiple lung metastases. Total en bloc spondylectomy and reconstruction with a frozen tumor-bearing bone graft were performed to treat the T4 metastasis...

Bin Liu, Zhenchao Yuan, Chang Yuan Wei
Objective: The incidence rate of thoracic metastasis from breast cancer is increasing. Microwave ablation is one type of clinical therapy used to treat metastatic spine disease, although it can cause protein denaturation and immediate cell death, and coagulative necrosis can occur. Minimally invasive open decompression is associated with lower rates of surgical complications in comparison to traditional open surgery. Therefore, it is an alternative therapeutic option for spinal metastases...

OBJECTIVE Intraoperative angiography can be a valuable tool in the surgical management of vascular disorders in the CNS. This is typically accomplished via femoral artery puncture; however, this can be technically difficult in patients in the prone position. The authors describe the feasibility of intraoperative angiography via the popliteal artery in the prone patient. METHODS Three patients underwent intraoperative spinal angiography in the prone position via vascular access through the popliteal artery. Standard angiography techniques were used, along with ultrasound and a micropuncture needle for initial vascular access...

Leptomeningeal metastases (LM) are a serious complication of cancer in the central nervous system (CNS) and are diagnosed in approximately 5% of patients with solid tumors. Effective treatment using systemically administered therapeutics is hindered by the barriers of the CNS. Ultrasound can mediate delivery of drugs through these barriers. The goal of this study was to test the feasibility of using ultrasound-mediated drug delivery to improve the treatment of LM. LM was induced in the spinal cord of athymic rats by injecting HER2-expressing breast cancer cells into the subarachnoid space of the thoracic spine...

This study aims to compare the effect of Philips' Brilliance 64-slice and 256-slice (multislice) computed tomography on effective doses when changing the operating parameters for simulated examinations of patients' spine tumors, including changes in pitch, tube voltage (kV), and effective tube current-time product (mA s). This study considers the possibility of using other probable operating conditions to reduce patients' effective doses. The absorbed doses to organs and skin are measured by taking data from thermoluminescent dosimeters (GR-200 and GR-200F) in relevant positions on the anthropomorphic Rando phantom...

BACKGROUND: Safe excision of spinal cord tumors depends on sufficient visualization of the tumor and surrounding structures. In patients with spinal cord tumor adjacent to a stenotic spinal canal, extensive bony decompression proximal and distal to the tumor should be considered for safer excision of the tumor. Extensive wide laminectomy is one choice for such cases, but postoperative problems such as kyphotic deformity remain a concern. CASE PRESENTATION: A 76-year-old man and a 60-year-old woman presented with symptomatic intradural extramedullary spinal cord tumors in the cervical spine...

OBJECTIVES: Patients with neoplastic disease involving the spine either from primary or metastatic disease present a unique challenge given these patients' frequent poor nutritional status at the time of surgery, the delivery of early post-operative chemotherapy or radiation, and placement of large amounts of hardware and avascular bone graft into a wound bed that is atrophic, previously operated or irradiated. As a result, wound morbidity has traditionally been high in this cohort of patients...

Sacral tumors continue to present a significant challenge to the spine surgeon. As new techniques have evolved in recent years, these lesions have become more amenable to aggressive surgical treatment. Although sacral tumors make up only a small minority of spinal tumors, the surgical management is well deserving of special consideration. To ensure a successful outcome - a goal-directed, methodical approach is required. Based on our experience, we highlight three important surgical nuances specifically for the treatment of sacral tumors including preservation and maximization of neurologic function, protection of ventral abdominal and pelvic structures, and lumbo-pelvic fixation...

Background: Spondylodiscitis (SD), the concurrent infection of a vertebral disc and the adjacent vertebral bodies, is a very severe disease that can lead to death or cause spinal deformities, segmental instabilities, and chronic pain, which significantly reduces the quality of life for affected patients. Early diagnosis and treatment are essential in order to reduce the risk of negative outcomes. The two cases of SD that are described in this paper might be useful for informing paediatric approaches to children with SD...
