==Additional Information== | |||
This disease is <u>defined/characterized</u> as detailed below: | |||
*This is a distinct entity in the World Health Organization (WHO) classification system within the section of Gliomas, Glioneuronal and neuronal tumours. This is a well-differentiated glioneuronal tumour with low proliferative activity, comprised of mixed neoplastic neuronal and glial cell components. It is molecularly characterized by genomic aberrations causing MAPK pathway activation (CNS WHO grade 1)<ref name=":0" />. | |||
The <u>epidemiology/prevalence</u> of this disease is detailed below: | |||
*Gangliogliomas are generally tumours of adolescent/young adults with a median age of 12 years at the time of diagnosis.

The mean duration of symptoms prior to diagnosis is also dependent on location.

The <u>morphologic features</u> of this disease are detailed below: | |||
*Ganglioglioma is a biphasic tumor composed of a neoplastic neuronal and a neoplastic glial component<ref name=":3" /><ref name=":5" />. The neoplastic neuronal component is comprised of dysmorphic ganglion cells showing cytomegaly, binucleation and perimembranous aggregation of Nissl substance. Disorganized cytoarchitecture is also observed, with clustering of neurons. The neoplastic glial component can resemble a diffuse glioma or pilocytic astrocytoma; the glial component harbors the proliferative component of the tumor, which can show infiltration on microscopy. Proliferative activity is usually low to absent. The two components can be intermingled or geographically distinct. Other pertinent histological features include Rosenthal fibres, eosinophilic granular bodies and perivascular lymphoid infiltration<ref name=":3" /><ref name=":5" />. An association with focal cortical dysplasia is a commonly reported finding<ref>{{Cite journal|last=Blümcke|first=Ingmar|last2=Thom|first2=Maria|last3=Aronica|first3=Eleonora|last4=Armstrong|first4=Dawna D.|last5=Vinters|first5=Harry V.|last6=Palmini|first6=Andre|last7=Jacques|first7=Thomas S.|last8=Avanzini|first8=Giuliano|last9=Barkovich|first9=A.
