In patients with tumors and spinal cord lesions, inflammation and tissue infection can result in mass effect detection on imaging. As a result, surgical biopsy procedures are often performed on the lesions. We report a rare case in which the thickening ligamentum flavum (LF) appeared to be a tumor in the epidural space of the cervical spine based on imaging findings. A 52-year-old man visited our outpatient clinic with severe shoulder pain and radicular pain in his right arm that had developed gradually after a traffic accident two months earlier...

Neurosarcoidosis is uncommon with an incidence of approximately 5 to 15%. Central nervous system involvement can be divided into brain and spinal cord neurosarcoidosis. Spinal cord sarcoidosis is extremely rare, occurring in less than 1% of all sarcoidosis cases. Its manifestations may include cauda equina syndrome, radiculopathy, syringomyelia, cord atrophy, arachnoiditis, and myelopathy or transverse myelitis. We highlight two cases of spinal cord sarcoidosis, each presenting with longitudinally extensive transverse myelitis, that demonstrate the dilemmas that physicians face with regard to diagnosis and treatment...

The radiographic appearance of bone metastases is usually determined by tumor histology and can be osteolytic, osteoblastic, or mixed. We present a patient with coexistent bone metastasis from multiple myeloma and prostate adenocarcinoma who exhibited synchronous bone involvement of both histologies within the same bone lesion, a rare phenomenon that has not been previously reported and led to atypical radiographic findings. The radiograph of a 71-year-old man with thigh swelling and pain demonstrated a lytic femoral lesion...

Background: Spinal cord involvement by schistosomiasis is considered to be rare. Clinical presentation of spinal schistosomiasis ranges from radicular pain to myelopathy causing flaccid paraplegia, bladder incontinence, and dysesthesia. We reported six cases with spinal schistosomiasis. Methodology: We did a retrospective analysis of the records in our department from March 1995 to March 2015, and we found that six cases of proved spinal schistosomiasis were documented, with follow-up period more than a year, aiming to find an assumption for a guideline for this ambiguous issue...

BACKGROUND: Angiocentric lymph proliferative disorder (ALPD) is a granulomatous lymphoproliferative condition associated with various primary and secondary immunodeficiency states. ALPD is so rare that its prevalence has not been established. Typically affecting middle-aged adults, this condition is often found in the context of Epstein Bar Virus infection and consists of angiocentric and angioinvasive pulmonary infiltrates. Herein, we present a biopsy-proven case of a patient manifesting with a viral meningoencephalomyelitis-like picture with brain, spinal cord, renal and splenic lesions...

STUDY DESIGN: Cadaveric study. OBJECTIVE: To establish the safety and efficacy of magnetically controlled growing rods (MCGRs) after magnetic resonance imaging (MRI) exposure. SUMMARY OF BACKGROUND DATA: MCGRs are new and promising devices for the treatment of early-onset scoliosis (EOS). A significant percentage of EOS patients have concurrent spinal abnormalities that need to be monitored with MRI. There are major concerns of the MRI compatibility of MCGRs because of the reliance of the lengthening mechanism on strongly ferromagnetic actuators...

The goal of developing computational models of spinal cord injury (SCI) is to better understand the human injury condition. However, finite element models of human SCI have used rodent spinal cord tissue properties due to a lack of experimental data. Central nervous system tissues in non human primates (NHP) closely resemble that of humans and therefore, it is expected that material constitutive models obtained from NHPs will increase the fidelity and the accuracy of human SCI models. Human SCI most often results from compressive loading and spinal cord white matter properties affect FE predicted patterns of injury; therefore, the objectives of this study were to characterize the unconfined compressive response of NHP spinal cord white matter and present an experimentally derived, finite element tractable constitutive model for the tissue...

Spinal neurosarcoidosis is a rare form of neurosarcoid which can be challenging to diagnose given its clinical or radiographic findings are often indistinguishable from other causes of spinal demyelinating disease. We present a series of three patients with spinal neurosarcoid, all of whom demonstrated concurrent longitudinally enhancing transverse myelitis as well as spinal nerve root enhancement. These findings may be suggestive of spinal neurosarcoid and may help clinicians make the diagnosis as well as reduce the need for invasive biopsy...

Several genes related to mitochondrial functions have been identified as causative genes of neuropathy or ataxia. Cytochrome c oxidase assembly factor 7 (COA7) may have a role in assembling mitochondrial respiratory chain complexes that function in oxidative phosphorylation. Here we identified four unrelated patients with recessive mutations in COA7 among a Japanese case series of 1396 patients with Charcot-Marie-Tooth disease (CMT) or other inherited peripheral neuropathies, including complex forms of CMT...

Extranodal lymphoma of the spine is often a late manifestation of systemic disease, and may result in symptoms of pain, neurologic compromise or spinal instability. Symptomatic relief is generally achieved by radiotherapy alone, but is not sufficient in addressing spinal instability. The indications for surgery remain controversial, but may be required for spinal stabilization, or refractory disease. Currently, there is a lack of studies that compare the indications and clinical outcomes of patients receiving surgical and nonsurgical management of spinal extranodal lymphoma...

Although the incidence of infection following vertebroplasty or kyphoplasty is rare, postoperative infection and cement augmentation in preexistent spondylitis can cause life-threatening complications in frail patients with notable comorbidities. In such cases, urgent culture and biopsy and the long-term use of proper antibiotics are necessary. PURPOSE: Infection following vertebral augmentation with polymethylmethacrylate (PMMA) is rare. We aimed to analyze 11 cases of pyogenic spondylitis and spondylodiscitis that occurred after vertebroplasty or kyphoplasty and to review similar cases in the literature...

Our previous studies have shown that severely atrophic Quadriceps muscles of spinal cord injury (SCI) patients suffering with complete conus and cauda equina lesions, and thus with permanent denervation-induced atrophy and degeneration of muscle fibers, were almost completely rescued to normal size after two years of home-based Functional Electrical Stimulation (h-bFES). Since we used large surface electrodes to stimulate the thigh muscles, we wanted to know if the skin was affected by long-term treatment. Here we report preliminary data of morphometry of skin biopsies harvested from legs of 3 SCI patients before and after two years of h-bFES to determine the total area of epidermis in transverse skin sections...

Cryptococcal meningoencephalitis is responsible for upwards of 15% of HIV-related deaths worldwide and is currently the most common cause of non-viral meningitis in the US, affecting both previously healthy and people with immune suppression caused by cancer chemotherapy, transplantation, and biologic therapies. Despite a continued 30-50% attributable mortality, recommended therapeutic strategies have remained largely unchanged since the 1950s. Recent murine models and human studies examining the role of the immune system in both susceptibility to the infection as well as host damage have begun to influence patient care decisions...

Approximately 70% of cancer patients will eventually develop bone metastases. Spine, due to the abundance of red marrow in the vertebral bodies and the communication of deep thoracic-pelvic veins with valve-less vertebral venous plexuses, is the most common site of osseous metastatic disease. Open biopsies run the risk of destabilizing an already diseased spinal or peripheral skeleton segment. Percutaneous biopsies obviate such issues and provide immediate confirmation of correct needle location in the area of interest...

PURPOSE: Tenosynovial giant cell tumor of the diffuse type (TGCT-D) involving the spine is rare. Its differential diagnosis includes metastatic disease; however, there have been few reports of spinal TGCT-D mimicking spinal metastasis in patients with a history of malignancy. METHODS: We report on a 35-year-old woman with a history of papillary thyroid cancer who was diagnosed with TGCT-D of the thoracic spine mimicking spinal metastasis. Preoperative computed tomography (CT) revealed a 1...

BACKGROUND AND PURPOSE: Vertebral hemangiomas are benign vascular lesions that are almost always incidentally found in the spine. Their classic typical hyperintense appearance on T1- and T2-weighted MR images is diagnostic. Unfortunately, not all hemangiomas have the typical appearance, and they can mimic metastases on routine MR imaging. These are generally referred to as atypical hemangiomas and can result in misdiagnosis and ultimately additional imaging, biopsy, and unnecessary costs...
