Hypoglossal neurinoma extending intra- and extracranially: case report

Surgical Neurology

Abstract

Hypoglossal neurinoma is very rare; our case is the 46th case. We report a 59-year-old woman with hypoglossal neurinoma. Her equilibrium state was disturbed due to vestibular dysfunction and she exhibited right hypoglossal palsy with glossal hemiatrophy. Computed tomography (CT) revealed a large bony erosion of the right hypoglossal canal. Magnetic resonance imaging (MRI) revealed intra- and extracranial tumor extension. There was an intracranial mass attached to the enlarged hypoglossal vertebral and posterior inferior cerebellar artery medially. The extracranial part of the mass extended along the course of the hypoglossal nerve through the enlarged hypoglossal canal. The intracranial part of the tumor was totally removed via the transcondylar approach. The diameter of the origin of the posterior interior cerebellar artery was narrow before tumor removal; it increased after surgery due to decompression. A histological diagnosis of neurilemoma was made. Her symptoms due to vestibular dysfunction disappeared postoperatively. Our patient's difficulty with balance was thought to be an ischemic symptom due to circulation disturbance of the posterior inferior cerebellar artery. It disappeared after tumor removal. Surgery may be nec...Continue Reading

COVID-19

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
