BACKGROUND: Thoracic corpectomies are performed for various reasons including spinal deformity, trauma, neoplasms, and infection. Regardless of indication, both anterior and posterior approaches are surgical options, selected based on pathology, anatomy, patient characteristics, and surgical experience. Risk profiles and outcomes for these procedures are poorly characterized, however, and the choice between the two approaches remains inconclusive. OBJECTIVE: To compare risk factors and complications for adult patients undergoing anterior and posterior thoracic corpectomies...

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...

INTRODUCTION: Brachytherapy is a major adjuvant modality for neoplasms, but few have trialed its use for spinal tumors. This study examines perioperative and oncological outcomes of malignant spinal tumor patients who underwent resection with intraoperative phosphorous-32 (P32) brachytherapy. METHODS: Consecutive adult patients who underwent P32 brachytherapy during malignant spinal tumor resection were retrospectively identified from 2014 to 2015. Complications, tumor recurrence, and survival were reviewed...

Ependymomas of the spinal cord remain confined to the CNS and vary in presentation, depending on WHO grade. Higher-grade lesions usually cannot be surgically removed due to their infiltrative growth pattern. Spinal cordectomy has been proposed as a rescue treatment to improve survival in patients with high-grade as well as recurrent lesions. This report details an instructive and unique case of long-term follow-up of a patient who underwent cordectomy from T-4 through S-5 for what was initially diagnosed as a high-grade glial neoplasm of the spinal cord in 1993...

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: Spinal chordomas are rare primary osseous tumors that arise from the remnants of the notochord. They are commonly considered slow-growing, locally invasive neoplasms with little tendency to metastasize, but the high recurrent rate of spinal chordomas may seriously affect the survival rate and quality of life of patients. The aim of the study is to describe the epidemiological data and determine the prognostic factors for decreased survival in patients with primary spinal chordoma...

PURPOSE OF REVIEW: This article discusses the diagnosis and management of neoplasms that affect the spinal cord as well as spinal cord disorders that can occur due to cancer treatments. RECENT FINDINGS: Neoplastic myelopathies are uncommon neurologic disorders but cause significant morbidity when they occur. Primary spinal cord tumors can be classified into intramedullary, intradural extramedullary, or extradural tumors. Diffuse gliomas and ependymal tumors are the most common intramedullary tumors...

The epidemiology of spinal cord disease in human immunodeficiency virus (HIV) infection is largely unknown due to a paucity of data since combination antiretroviral therapy (cART). HIV mediates spinal cord injury indirectly, by immune modulation, degeneration, or associated infections and neoplasms. The pathologies vary and range from cytotoxic necrosis to demyelination and vasculitis. Control of HIV determines the differential for all neurologic presentations in infected individuals. Primary HIV-associated acute transverse myelitis, an acute inflammatory condition with pathologic similarities to HIV encephalitis, arises in early infection and at seroconversion...

Neurofibromatosis type 1 associates with multiple neoplasms and the Schwann cell tumor neurofibroma is the most prevalent. A hallmark feature of neurofibroma is mast cell infiltration which is recruited by chemoattractant stem cell factor (SCF) that has been suggested to sustain neurofibroma tumorigenesis. In this study, using new genetically engineered Scf mice, we decipher the contributions of tumor-derived SCF and mast cells to neurofibroma development. We demonstrate that mast cell infiltration is dependent on SCF from tumor Schwann cells...

BACKGROUND: Malignant mesotheliomas are aggressive and rapidly-fatal neoplasms arising from the mesothelial cells. The most common sites of origin are the pleural and peritoneal cavities, and additionally, malignant mesotheliomas can also infrequently involve the pericardium and the tunica vaginalis. However, malignant mesothelioma occurring in the spinal canal is extremely rare. Herein, we reported a case with primary spinal malignant mesothelioma. METHODS: A literature search was using PubMed with specific key terms, inclusion criteria, and exclusion criteria...

Solitary fibrous tumours/haemangiopericytomas (SFT/HPC) are fibroblastic mesenchymal neoplasms that harbour a genetic fusion of NAB2/STAT6. There are few reported cases in the central nervous system (CNS), of which spinal tumours are minority. We present a case of a 63-year-old woman with progressive paraparesis and a sensory level of T6. On the MRI we detected an intradural extramedullary lesion on T9-T10. We performed a laminectomy with an intraoperative ultrasound study in which we observed a heterogeneous lesion with an infiltrating pattern affecting the medulla at several points, and resection of the lesion...

OBJECTIVE Spinal ependymomas are rare glial neoplasms. Because their incidence is low, only a few larger studies have investigated this condition. There are no clear data concerning prognosis and therapy. The aim of the study was to describe the natural history, perioperative clinical course, and local tumor control of adult patients with spinal ependymomas who were surgically treated under modern treatment standards. METHODS The authors performed a multicenter retrospective study. They identified 158 adult patients with spinal ependymomas who had received surgical treatment between January 2006 and June 2013...

BACKGROUND: Thoracic spine cancer metastases is frequently the cause of neurological deficits. Despite the availability of diagnostics, delays in treatment are still quite common. The aim of this work is to analyze the reasons for delayed diagnostics and treatment, in patients with neurological deficits in the course of metastatic spine disease. METHODS: In our study patients medical data was analyzed from 2013 to 2015. The analysis covered the following aspects: symptoms of metastases, time of neurological deficits occurrence, where and when initial diagnostics were performed, time from diagnosis to proper surgical treatment in an oncological centre...

N-methyl-D-aspartate receptor encephalitis (NMDARe) is one of 13 autoimmune-mediated encephalitides that have been discovered over the last decade. This case report describes the course of a 26-year-old female who presented with new-onset seizures and insomnia, complicated by encephalitis. The initial workup ruled out common causes of encephalitis, while a transvaginal ultrasound (TVUS), and computed tomography (CT) scans of the chest, abdomen, and pelvis did not identify a mass. Based on the suspicion that she may have autoimmune encephalitis, the patient was treated with intravenous immunoglobulins and plasma exchange, but continued to deteriorate...

BACKGROUND: Germ cell tumors (GCTs) in children are rare neoplasms with diverse pathological findings according to the site and age of presentation. The most common symptoms in children with mediastinal GCTs, which are nonspecific, are dyspnea, chest pain, cough, hemoptysis, vena cava occlusion syndrome, and fatigue/weakness. Because of these nonspecific symptoms, it is difficult to suspect a mediastinal mass. A posterior mediastinal tumor causing spinal cord compression is an important example of an oncologic emergency arising from a neurogenic tumor...

Giant cell tumors (GCTs) are rare, benign, and locally aggressive primary bone neoplasms. Spine is seldom affected, especially above the level of sacrum. In this report, we describe a case with GCT of the cervical vertebrae which causes collapse of the corpus. A 32-year-old female presented with gradual neck pain and abrupt paresthesia of the left hand. Computed tomography scan showed C6 vertebral collapse and magnetic resonance imaging demonstrated vertebral plana of C6 by a low signal intensity lesion on T1- and T2-weighted images...

Background: Primary spinal cord tumors are not as frequently encountered as their cranial counterparts. They could present in such an indolent manner that requires a reasonable index of suspicion for their diagnosis to be considered. Objective: The objective of this study is to analyze the incidence and pattern of primary spinal cord and appendage neoplasms in patients surgically treated in our institution over a decade of practice. Materials and Methods: A retrospective review of clinical, radiological, and histopathology profiles of patients surgically treated for primary spinal cord tumor from 2006 to 2016 was carried out...

PURPOSE: Cervicothoracic paravertebral neoplasms extending into the mediastinum pose a surgical challenge due the complex regional anatomy, their biological nature, rarity and surgeon's unfamiliarity with the region. We aim to define a surgical access framework addressing the aforementioned complexities whilst achieving oncological clearance. METHODS: We carried out a retrospective review of 28 consecutive patients operated in two tertiary referral centres between 1998 and 2015...

Spinal cord infarction (SCI) is a rare type of stroke. The initial magnetic resonance imaging (MRI) is usually normal and can mimic the presentation of the acute transverse myelitis (ATM), acute inflammatory demyelinating polyneuropathy, and compressive myelopathies from neoplasm, epidural or subdural hematoma, or abscess. The aim of this report is to describe and discuss the case of a patient with SCI presenting as a diagnostic confusion with acute transverse myelitis. A 64-year-old male with a medical history of hypertension presented with an acute onset of urinary retention with lower limb weakness...

Paragangliomas are benign neoplasms that arise from the autonomic nervous system and the associated paraganglia. Although benign, they have been shown to possess metastatic potential. Involvement of the spine is rare. Even rarer is considered the involvement of the cervical spine. We report a case of a patient with a history of an extra-adrenal non-functional paraganglioma of the jugular foramen which was initially treated with intra-arterial embolization. After a 3-year disease-free follow-up, the patient was presented with symptoms of spinal cord compression due to spinal metastases in C2 and C3 vertebrae...
