Gliomatosis cerebri is a rare subtype of glioma involving more than three lobes of the central nervous system. Currently, diagnosis of gliomatosis cerebri can be confirmed pathologically, surgically, or with magnetic resonance imaging that shows high-signal areas expanding to the cerebral hemisphere, brain stem, cerebellum, and spinal cord. Although this disease has great clinical importance, it has recently been removed from the revised WHO classification of Tumors of the Central Nervous System (2016) owing to divergence between its morphological features and molecular profiles...

Spinal cord glioma is uncommonly reported in dogs. We describe the clinicopathologic and diagnostic features of 7 cases of canine spinal cord glioma and briefly review the veterinary literature on this topic. The median age at presentation was 7.2 y. Six females and 1 male were affected and 4 dogs were brachycephalic. The clinical course lasted from 3 d to 12 wk, and clinical signs were progressive and associated with multiple suspected neuroanatomic locations in the spinal cord. Magnetic resonance imaging of 6 cases revealed T2-weighted hyperintense lesions with variable contrast enhancement in the spinal cord...

Normal brain cells depend on glucose metabolism, yet they have the flexibility to switch to the usage of ketone bodies during caloric restriction. In contrast, tumor cells lack genomic and metabolic flexibility and are largely dependent on glucose. Ketogenic-diet (KD) was suggested as a therapeutic option for malignant brain cancer. This study aimed to detect metabolic brain changes in patients with malignant brain gliomas on KD using proton magnetic-resonance-spectroscopy ((1)H-MRS). Fifty MR scans were performed longitudinally in nine patients: four patients with recurrent glioblastoma (GB) treated with KD in addition to bevacizumab; one patient with gliomatosis-cerebri treated with KD only; and four patients with recurrent GB who did not receive KD...

We present the case of a 43-year-old lady who presented with headaches, visual impairment, and seizures, progressing rapidly over the course of a few weeks. Extensive workup excluded an inflammatory or infectious cause. Imaging studies revealed diffuse thickening of the leptomeninges and serial CSF analysis showed raised opening pressures and increased protein levels. A diagnostic biopsy of the lower thoracic dura confirmed the diagnosis of primary diffuse leptomeningeal gliomatosis (PDGL). She was managed supportively for her symptoms and unfortunately she passed away a few weeks later...

BACKGROUND: Gliomatosis cerebri is a rare diffusely infiltrating malignant glial neoplasm. Presenting symptoms include seizures, neurologic deficits, and frequently symptoms related to increased intracranial pressure (ICP). Surgical intervention, including brain biopsy, may induce worsening of these neurologic symptoms. We reviewed our database to identify prognostic and risk factors for perioperative deterioration specifically associated with elevated ICP. METHODS: Between 2006 and 2014, 78 patients were treated for gliomatosis cerebri...

Extragonadal teratomas are rare, and localization in the endometrium and cervix is exceptional, with fewer than 10 case reports documented so far in the English literature. We report here the case of a 46-year-old patient who presented with simultaneous immature teratoma in the endometrium and mature teratomas in the ovary in association with gliomatosis peritonei but with no evidence of gestational origin; she subsequently developed multiple solid mature teratomas in the cervix and parauterine tissue. No other similar cases have been previously reported to our knowledge...

Recurrent high-grade gliomas (HGGs) of childhood have an exceedingly poor prognosis with current therapies. Accordingly, new treatment approaches are needed. We initiated a pilot trial of vaccinations with peptide epitopes derived from glioma-associated antigens (GAAs) overexpressed in these tumors in HLA-A2+ children with recurrent HGG that had progressed after prior treatments. Peptide epitopes for three GAAs (EphA2, IL13Rα2, survivin), emulsified in Montanide-ISA-51, were administered subcutaneously adjacent to intramuscular injections of poly-ICLC every 3 weeks for 8 courses, followed by booster vaccines every 6 weeks...

Gliomatosis peritonei (GP) is characterized by the presence of benign, mature neuroglial implants throughout the peritoneum and is typically accompanied by mature or immature ovarian teratomas. GP is a condition that has only been described relatively recently, with ~100 cases reported in the English literature. The majority of reported cases have focused on the pathology and clinical treatment of the disease; radiological findings are distinct, but the discussion of this is scarce in the literature. The current study presents two cases of GP with bilateral ovarian teratomas and provides a review of the relevant literature, with particular emphasis on the radiological differential diagnosis...

BACKGROUND: Gliomatosis peritonei (GP) is a rare condition characterized by mature glial tissue implants widespread in the peritoneum. The GP is often associated with ovarian teratoma. However, little is known about the characteristics and prognosis of GP. The purpose of this study was to describe the features, treatment, and prognosis of GP. Additionally, we review previously reported cases of GP, summarizing the presently known data. METHODS: From January 2000 to January 2016, cases of ovarian teratoma and GP treated at Peking Union Medical College Hospital were reviewed...

Gliomatosis cerebri (GC) is a universally fatal extensive and diffuse infiltration of brain parenchyma by a glial tumor. Many aspects of this phenomenon remain unknown. The First International Gliomatosis cerebri Group Meeting had the following goals: refine the clinical and radiologic diagnostic criteria for GC, suggest appropriate diagnostic procedures, standardize tissue manipulation for histologic and molecular characterization, and prioritize relevant preclinical projects. Also, general treatment recommendations were outlined for the pediatric population...

CONTEXT: Glioblastoma is a malignant brain tumor originating in the central nervous system. Successfully therapy of this disease required the efficient delivery of therapeutic agents to the tumor cells and tissues. Delivery of anticancer drugs using novel nanocarriers is promising in glioma treatment. OBJECTIVE: Polymeric nanoparticles (PNPs), solid lipid nanoparticles (SLNs), and nanostructured lipid carriers (NLCs) were constructed for the delivery of temozolomide (TMZ)...

Novel therapies, including molecular targeted therapies, are being developed for the treatment of human gliomas. To use such therapies for canine gliomas, more complete characterization of molecular targets is required. Epidermal growth factor receptor (EGFR) is one such therapeutic target used in human glioma trials, and the Ki-67 labeling index (LI) is a marker of proliferation and a prognostic indicator. The objectives of this cross-sectional study were to evaluate the expression of EGFR and Ki-67 in canine gliomas and to determine if immunopositivity is associated with tumor type and histologic grade...

The constitutional MisMatch Repair deficiency (CMMRD) syndrome is one of the inherited cancer predisposition syndromes. More than two-third patients belonging to a CMMRD family are diagnosed mainly in the first decade with brain cancers and/or hematological malignancies. This syndrome is due to bi-allelic germline mutations in genes of the MMR pathway (MLH1, MSH2, MSH6 or PMS2). Our family report begins with the index case presenting initially with a medulloblastoma, which was even the two relapses in complete remission, when she was diagnosed for an AML...

Accurate glioma sampling is required for diagnosis and establishing eligibility for relevant clinical trials. MR-based perfusion and spectroscopy sequences supplement conventional MR in noninvasively predicting the areas of highest tumor grade for biopsy. We report the case of a patient with gliomatosis cerebri and multifocal patchy enhancement in whom the combination of advanced and conventional imaging attributes successfully guided a diagnostic biopsy.

Gliomatosis cerebri (GC) is a diffuse infiltrating glial neoplasm of astrocytic origin. GC in children is rare and difficult to diagnose, often presenting with a variety of signs and symptoms that may mimic myriad conditions. We discuss here the presentation and diagnosis of GC in a child who was initially treated on lines of tubercular encephalitis, with transient clinical relief and disappearance of enhancing component of the disease on magnetic resonance imaging. In this report, we highlight the limitations of clinical presentation and neuroimaging as well as the essential role of histological evaluation for the diagnosis of GC in children...
