Objective and Importance:

Ganglioglioneurocytoma is not yet a well defined clinical and histopathological entity; recent reports outline the histopathological features of this very rare trimorphous tumor, under different names with its basic components of gangliocytoma, neurocytoma and glioma. Four previous reports described this tumor in eleven patients. This is the first case report describing ganglioglioneurocytoma in the posterior fossa.

Clinical Presentation and Intervention:

A 31-year old male with midline posterior fossa ganglioglioneurocytoma is described, providing the neuroimages and histopathological studies.

Conclusion:

Ganglioglioneurocytoma is a rare mixed neuronal and glial tumor that can also occur in the posterior fossa.

Résumé

RÉSUMÉ<span class='bold'><span class='italic'>Objectif et importance:</span></span>

Le ganglioglioneurocytome est encore une entité clinique et histopathologique mal définie. Des rapports récents décrivent sous des noms dif- férents les caractéristiques histopathologiques de cette tumeur très rare, possédant trois composantes de base, le gan- gliocytome, le neurocytome et le gliome. Quatre rapports antérieurs décrivent cette tumeur chez onze patients. Nous présentons le premier cas d’un ganglioglioneurocytome de la fosse postérieure.

<span class='italic'><span class='bold'>Présentation clinique et intervention:</span></span>

Nous décrivons le cas d’un homme âgé de trente et un ans porteur d’un ganglioglioneurocytome médian de la fosse postérieure et nous en présentons la neuro-imagerie et l’anatomopathologie.

<span class='italic'><span class='bold'>Conclusion:</span></span>

Le ganglioglioneu- rocytome est une tumeur mixte neuronale et gliale rare qui peut également être localisée dans la fosse postérieure.
