A collision tumor between these two entities has not previously been reported. The patient is a 35\u2010year\u2010old woman who presented with new\u2010onset hearing loss and ringing in her right ear. Magnetic resonance imaging identified a non\u2010enhancing mass involving the gray matter and subcortical white matter of the left middle frontal gyrus. Additionally, tiny clustered nodules were noted along the underlying subcortical ribbon and superficial subcortical white matter of the left superior frontal gyrus. The patient underwent a left frontal craniotomy and complete resection of the mass. Histologic examination of the resected specimen demonstrated a collision tumor consisting of a diffuse astrocytoma (isocitrate dehydrogenase [IDH] mutant, central nervous system [CNS] World Health Organization [WHO] grade 2) and an MVNT, with the latter demonstrating characteristic morphologic and immunohistochemical features.<\/jats:p>","DOI":"10.1111\/neup.12968","type":"journal-article","created":{"date-parts":[[2024,2,28]],"date-time":"2024-02-28T04:55:15Z","timestamp":1709096115000},"page":"333-337","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Collision
