Resection of a Symptomatic Dysplastic Cerebellar Gangliocytoma: 2-Dimensional Operative Video

Operative Neurosurgery
Tarek Y El AhmadiehToral Patel


Lhermitte-Duclos disease, also known as dysplastic cerebellar gangliocytoma, is a rare benign cerebellar tumor that is typically observed but may occasionally become symptomatic and requires surgical intervention. The condition is caused by a mutation in the phosphatase and tensin homolog (PTEN) gene, which results in dysregulation of the mammalian target of rapamycin pathway. A germline PTEN mutation results in multi-organ involvement and is termed Cowden syndrome. There is a scarcity of surgical videos in the published literature that demonstrate an intraoperative resection of this lesion and illustrate the pathology in Vivo. We present an operative video of a surgical resection of a symptomatic dysplastic cerebellar gangliocytoma in a 44-yr-old male patient who presented with a 3-mo history of progressive headaches and hydrocephalus. The patient underwent an endoscopic third ventriculostomy and, subsequently, a right suboccipital craniotomy for microsurgical resection of the mass. The procedure was performed with the patient in the lateral position. The microscope was positioned at the head of the bed and the stereotaxic system monitor on the patient's left side. The patient tolerated the procedure well and imaging obtained ...Continue Reading

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Autism: Motor Learning

A common feature of autism spectrum disorder (ASD) is the impairment of motor control and learning, consistent with perturbation in cerebellar function. Find the latest research on ASD and motor learning here.

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.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration

Protein Localization in Disease & Therapy

Localization of proteins is critical for ensuring the correct location for physiological functioning. If an error occurs, diseases such as cardiovascular, neurodegenerative disorders and cancers can present. Therapies are being explored to target this mislocalization. Here is the latest research on protein localization in disease and therapy.

Genetic Screens in Bacteria

Genetic screens can provide important information on gene function as well as the molecular events that underlie a biological process or pathway. Here is the latest research on genetic screens in bacteria.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.
