A rare case of intraventricular gangliocytoma

Pessoa Correa et al present a rare case of intraventricular gangliocytoma. A 49-year-old man presented to the emergency department after cranioencephalic trauma with an intraventricular tumor detected in the computed tomography (CT) scan. An magnetic resonance image (MRI) showed a heterogeneous expansive lesion with enhancing solid components and peripheral cysts located in the left lateral ventricle. The patient underwent excision of the lesion. Histopathologic and immunohistochemical analysis revealed the diagnosis of gangliocytoma. Gangliocytomas are rare low-grade central nervous system tumors composed of dysplastic ganglion cells, usually presenting in children or young adults and located in the cerebral hemispheres. Until now, there are no case reports of intraventricular gangliocytoma.
