BACKGROUND: Preoperative embolization (PE) may decrease intraoperative blood loss (IBL) in decompressive surgery of hypervascular spinal metastases. However, no consensus has been found in other metastases and no meta-analysis which reviewed the benefit of PE in spinal metastases has been conducted. OBJECTIVE: To assess IBL in spinal metastases surgery in a randomized controlled trial (RCT) and cohort studies comparing PE and a control group of non-embolized patients...

Spinal laser interstitial thermal therapy (LITT) appears to be a promising novel modality for treatment of epidural metastatic spine disease in patients who are poor candidates for larger-scale oncologic spinal surgery and can act synergetically with spinal stereotactic radiosurgery to maximize local control and palliate pain. This technique is ideally suited for the intraoperative MRI suite to monitor the extent of the ablation in the epidural space. As percutaneous navigation, imaging, and LITT technology improve, broader applicability of this minimally invasive technique in spinal oncology is foreseen...

Intraoperative imaging has become widely accepted in neurosurgery in recent years. The possibility to objectively determine the extent of tumor removal is highly advantageous. If the resection is incomplete, clinicians can attempt to remove the residual tumor that was missed during the same operation. Furthermore, the positioning of implants in spinal surgery, as well as in cranial surgery, can be controlled and modified during the procedure. Intraoperative imaging acts as immediate quality control and offers improved patient safety...

Spine is a common site of metastases in cancer patients. Spine surgery is indicated for select patients, typically those with mechanical instability and/or malignant epidural spinal cord (or cauda equina) compression. Although post-operative conventional palliative external beam radiation therapy has been the standard of care, technical improvements in radiation planning and image-guided radiotherapy have allowed for the application of stereotactic body radiotherapy (SBRT) to the spine. Spine SBRT is intended to ablate residual tumor and optimize local control by delivering several fold greater biologically effective doses...

BACKGROUND AND PURPOSE: Chordomas notoriously demonstrate a paucity of changes following radiation therapy on conventional MR imaging. We hypothesized that dynamic contrast-enhanced MR perfusion imaging parameters of chordomas would change significantly following radiation therapy. MATERIALS AND METHODS: Eleven patients with pathology-proved chordoma who completed dynamic contrast-enhanced MR perfusion imaging pre- and postradiation therapy were enrolled. Quantitative tumor measurements were obtained by 2 attending neuroradiologists...

Intrapelvic sciatic nerve schwannomas are rare causes for non-discogenic sciatica. We describe a 44-year-old female who had a palpable mass on digital rectal examination that exhibited a positive Tinel's sign. The schwannoma was excised by a posterior transgluteal approach. Patients with negative spinal imaging should undergo pelvic scanning to rule out these tumors.

Ovarian germ cell tumors (GCTs) are rare and affect mainly young girls and women. Two histological groups are distinguished: dysgerminomas and nondysgerminomatous tumors. These tumors have initial good responses to surgery and chemotherapy in 80% cases, but >75% of patients die due to complications of disease progression. There are very few case reports of mixed GCT with extradural spine metastases. We report a rare case of a 17-year-old girl who had undergone left salpingo-oophorectomy with omental and peritoneal biopsy for ovarian GCT with extradural spinal metastasis...

Cerebrospinal fluid (CSF) represents a promising source of cell-free DNA (cfDNA) for tumors of the central nervous system. A CSF-based liquid biopsy may obviate the need for riskier tissue biopsies and serve as a means for monitoring tumor recurrence or response to therapy. Spinal ependymomas most commonly occur in adults, and aggressive resection must be delicately balanced with the risk of injury to adjacent normal tissue. In patients with subtotal resection, recurrence commonly occurs. A CSF-based liquid biopsy matched to the patient's spinal ependymoma mutation profile has potential to be more sensitive then surveillance MRI, but the utility has not been well characterized for tumors of the spinal cord...

Multiple sclerosis (MS) is a severe autoimmune disease characterized by inflammatory, demyelinating and neurodegenerative components causing motor, sensory, visual and/or cognitive symptoms. The relapsing-remitting MS affecting 85% of patients is reliably mimicked by the proteolipid-protein (PLP)-induced experimental autoimmune encephalomyelitis (EAE) SJL/J-mouse model. Significant progress was made for MS treatment but the development of effective therapies devoid of severe side-effects remains a great challenge...

Meningioma is one of the commonest spinal tumors, with a predilection for intradural occurrence. Its occurrence as an extradural, en-plaque variety is uncommon. We report an en-plaque extradural cervical meningioma with a diffuse involvement of the brachial plexus. The imaging features of this unusual behaviour of a spinal meningioma and the treatment options are discussed in the light of a brief literature review.

Long-range enhancer interactions critically regulate gene expression, yet little is known about how their coordinated activities contribute to CNS development or how this may, in turn, relate to disease states. By examining the regulation of the transcription factor NFIA in the developing spinal cord, we identified long-range enhancers that recapitulate NFIA expression across glial and neuronal lineages in vivo. Complementary genetic studies found that Sox9-Brn2 and Isl1-Lhx3 regulate enhancer activity and NFIA expression in glial and neuronal populations...

Spinal subdural hematomas (SSDHs) are rare and usually associated with bleeding diatheses, trauma, iatrogenic injury, spinal vascular malformations, or intraspinal tumors. We report a case of a 75-year-old male who developed a symptomatic lumbosacral SSDH after undergoing resection of a right temporal glioblastoma multiforme. The patient subsequently recovered and was discharged home. Over the next two weeks he developed progressively worsening symptoms of lower back pain, lower extremity weakness, and urinary retention...

Extramammary Paget disease is an intraepithelial neoplasm affecting cells rich in apocrine glands-often located in the vulvar, scrotal, or perianal region. It typically affects older patients, between the ages of 50 and 80years old, and is most often limited to the epidermis. A 47-year-old Asian male first presented with enlargement of the right inguinal lymph node. A subsequent biopsy revealed extrammamary Paget disease of the scrotum. The patient eventually developed significant worsening back pain with bilateral lower extremity numbness and weakness three months later...

Hair follicle-associated-pluripotent (HAP) stem cells are located in the bulge area of the hair follicle, express the stem-cell marker, nestin, and have been shown to differentiate to nerve cells, glial cells, keratinocytes, smooth muscle cells, cardiac muscle cells, and melanocytes. Transplanted HAP stem cells promote the recovery of peripheral nerve and spinal cord injuries and have the potential for heart regeneration as well. In the present study, we implanted mouse HAP stem-cell spheres encapsulated in polyvinylidene fluoride (PVDF)-membrane cylinders into the severed sciatic nerve of immunocompetent and immunocompromised (nude) mice...
