Central neurocytoma--case report

Neurologia Medico-chirurgica
Y SugitaM Morimatsu


A 29-year-old male was admitted with chronic headache on February 26, 1987, when there were no neurological deficits or physical abnormalities. Computed tomographic (CT) scans showed a mixed-density mass with no evidence of calcification in the left lateral ventricle, which was irregularly enhanced by contrast medium. Under a diagnosis of an intraventricular glial tumor, surgery was performed via a left transcortical-transventricular approach on March 31. The highly vascular, nodular tumor, originated from the lateral wall of the left lateral ventricle near the foramen of Monro, was successfully removed. The postoperative course was uneventful and he was discharged 3 months after postoperative irradiation. Light microscopic examination revealed the tumor cells with the clear cytoplasm and perinuclear halos characteristic of an oligodendroglioma. However, electron microscopy showed neuronal elements identical with central neurocytoma as reported by Hassoun et al. in 1982. These included large numbers of dense-core or clear vesicles in the cell processes and synaptic structures.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
