The next edition of Tumors of the Central Nervous System is here! Impactful new discoveries, evolving diagnostic classifications, and rapid technical advances have reshaped the field. Having this essential atlas is key for supporting every practicing diagnostic pathologist.

This 45-year-old patient underwent sural nerve biopsy to evaluate for potential etiologies of their progressive sensorimotor predominantly axonal polyneuropathy. An extensive clinical workup did not identify a clinical cause for the patient’s neuropathy (i.e. idiopathic). What

Check out Dr. Brat’s feature in The Pathologist where he reflects on his career as a neuropathologist and gives advice to those considering the specialty. @DanielJBrat @pathologistmag https://t.co/ncBlZYwXuz

This cohort study suggests that chromosomal alterations should be included in the WHO grading criteria for meningiomas, as they are associated with worse outcomes and can refine the current classification system. https://t.co/E2OURavMVY @DrAMansouri @afgao

UHN marks the passing of Dr. James Till, whose work with Dr. Ernest McCulloch first demonstrated the existence of blood-forming stem cells in 1961 at Ontario Cancer Institute, now Princess Margaret Cancer Centre. His work has helped launch the field of #stemcell science.

Excited to share our first lab paper, now published in @Dev_Cell! 🧠 How do glioblastoma (GBM) cells invade the brain, and what enables them to spread so effectively?

New in Nature Cancer: CANON co-lead Dr. Julie Bennett and team show that 31% of AYA gliomas carry pediatric-type alterations. Findings highlight the need for age-specific approaches to diagnosis and treatment.

This 40-year-old patient has increasing back pain and lower extremity paraparesis. MRI of the cervical and lumbar spine with and without contrast showed multiple intradural leptomeningeal enhancing masses (spinal dissemination) with compression of the conus medullaris region.

Diffuse astrocytoma, MYB or MYBL1-altered. An infiltrating, but grade 1 glioma! (Note the trapped neurons—evidence of infiltration) Tumor cells rel. monomorphic, round to ovoid or spindly. It is strongly associated with epilepsy. #neuropath #neuropathology #pathx #PathTwitter

This new report by several ICOM authors in @JAMAOnc highlights the importance of a role for #CytogeneticProfiling in the next iteration of #CNS WHO grading. Read now: https://t.co/zivs2kY5Lx @ap_landry @FarshadNassiri @justinzw @gelarehzadeh @Kenneth_Aldape @sahm_lab @afgao

Intramedullary spinal tumor in a young woman. FISH showed apparent 1p/19q codeletion. Other molecular findings include BRAF fusion. Diagnosis? (You don't need to consult the Division for Lizard Governance and New Taxes to get this one right.😁) #pathology #neuropath #pathtwitter
