Spinal metastases are rare in head and neck cancer. We present a rare case of vocal cord squamous cell cancer that metastasized to the spinal cord and cauda equina. A 63-year-old man presented with acute back pain and bilateral leg weakness 5 months after having a surgical treatment for moderately differentiated vocal cord squamous cell cancer (T2 N0 M0). Restaging F-FDG PET examination demonstrated a soft tissue mass with intense hypermetabolism in the distal spinal cord and a hypermetabolic leptomeningeal metastatic deposit at the L3 level...

Leptomeningeal seeding is a strong negative prognostic factor for medulloblastoma (MB). The mechanism of leptomeningeal seeding is unclear but may involve epigenetic regulation. In this study, we evaluated the feasibility of a histone deacetylase (HDAC) inhibitor, panobinostat, in the suppression of MB leptomeningeal seeding. Panobinostat decreased the cell viability and proliferation, inducing cell cycle arrest and apoptosis in MB cell lines. The migration and adhesion capabilities were significantly decreased...

Postcontrast 3-dimensional fluid-attenuated inversion recovery (3D-FLAIR) sequences have reduced vascular and flow-related artifacts and high sensitivity to low gadolinium concentrations. We compared the performance of postcontrast spoiled gradient echo images to 3D-FLAIR in the detection of leptomeningeal metastases in 47 pediatric patients with brain tumors. We found 10 cases with more leptomeningeal signal abnormalities on 3D-FLAIR. Overall there were significantly more lesions on 3D-FLAIR than spoiled gradient echo sequences...

Leptomeningeal carcinomatosis (LMC) from gastrointestinal cancer is rare. A 56-year-old man with complaint of upper abdominal pain exhibited adenocarcinoma upon histopathologic examination of biopsy specimens. At the end of adjuvant chemotherapy, the patient was affected by hearing loss. Malignant cells were observed by cerebrospinal fluid (CSF) cytology. Therefore, the patient received intrathecal methotrexate and oral temozolomide chemotherapy and radiotherapy. The progress-free survival was approximately 11 months...

INTRODUCTION: Magnetic resonance imaging (MRI) has an important impact in diagnosing primary angiitis of the central nervous system (PACNS). However, neuroradiologic findings may vary immensely, making an easy and definite diagnosis challenging. METHODS: In this retrospective, single center study, we analyzed neuroradiologic findings of patients with PACNS diagnosed at our hospital between 2009 and 2014. Furthermore, we classified patients according to the affected vessel size and compared imaging characteristics between the subgroups...

While it is recognized that aquaporin-4 (AQP4)-specific T cells and antibodies participate in the pathogenesis of neuromyelitis optica (NMO), a human central nervous system (CNS) autoimmune demyelinating disease, creation of an AQP4-targeted model with both clinical and histologic manifestations of CNS autoimmunity has proven challenging. Immunization of wild-type (WT) mice with AQP4 peptides elicited T cell proliferation, although those T cells could not transfer disease to naïve recipient mice. Recently, two novel AQP4 T cell epitopes, peptide (p) 135-153 and p201-220, were identified when studying immune responses to AQP4 in AQP4-deficient (AQP4(-/-)) mice, suggesting T cell reactivity to these epitopes is normally controlled by thymic negative selection...

INTRODUCTION: Synchronous involvement of the central nervous system (CNS) at the diagnosis of systemic non-Hodgkin lymphoma (NHL) is associated with an increased risk for relapse despite complete remission to initial therapy. High-dose chemotherapy with a CNS-directed conditioning regimen followed by autologous stem cell transplantation (ASCT) holds promise as a consolidative approach. PATIENTS AND METHODS: We conducted a retrospective analysis of all patients with systemic B-cell NHL and synchronous CNS involvement who received upfront consolidation with high-dose chemotherapy with thiotepa, busulfan, cyclophosphamide, and ASCT while in first complete remission between July 2008 and June 2016 at 2 partner academic institutions...

In amyloid β-related angiitis of the central nervous system (also called cerebral amyloid angiopathy-related inflammation), cerebral amyloid angiopathy occurs in association with primary vasculitis of small- and medium-sized leptomeningeal and cortical arteries. To avoid brain biopsy, clinicoradiological criteria (including clinical features due to inflammation-related uni/multifocal white matter hyperintensities) for the diagnosis of cerebral amyloid angiopathy-related inflammation have been validated recently...

OBJECTIVE In the present study the authors aimed to determine preferred locations of meningiomas by avoiding descriptive analysis and instead using voxel-based lesion mapping and 3D image-rendering techniques. METHODS Magnetic resonance images obtained in 248 treatment-naïve meningioma patients with 260 lesions were retrospectively and consecutively collected. All images were registered to a 1-mm isotropic, high-resolution, T1-weighted brain atlas provided by the Montreal Neurological Institute (the MNI152), and a lesion frequency map was created, followed by 3D volume rendering to visualize the preferred locations of meningiomas in 3D...

Aims: Medin is a common amyloidogenic protein in humans that accumulates in arteries with advanced age and has been implicated in vascular degeneration. Medin's effect on endothelial function remains unknown. The aims are to assess medin's effects on human arteriole endothelial function and identify potential mechanisms underlying medin-induced vascular injury. Methods and results: Ex vivo human adipose and leptomeningeal arterioles were exposed (1 h) to medin (0...

INTRODUCTION: Dysfunction of the third cranial nerve can result from lesions anywhere along its course between the midbrain and the orbit. Lymphoma is a rare cause of isolated oculomotor nerve palsy (OMP), with only 19 cases reported in the literature. We describe a case of an isolated OMP leading to the diagnosis of disseminated Burkitt lymphoma (BL). CASE REPORT: A 37-year-old man presented with acute onset diplopia and right ptosis and was found to have a right pupillary sparing OMP...

Only two prior cases of benign dendritic melanocytes colonizing a meningioma have been reported. We add a third case, describe clinicopathologic features shared by the three, and elucidate the risk factors for this very rare phenomenon. A 29 year-old Hispanic woman presented with headache and hydrocephalus. MRI showed a lobulated enhancing pineal region mass measuring 41 mm in greatest dimension. Subtotal resection of the mass demonstrated an atypical meningioma, WHO grade II, and the patient subsequently underwent radiotherapy...
