Desmoplastic Non-Infantile Ganglioglioma; AnIncidental Finding with Unusual Localization by
Dimitrios Kanakis in Techniques in Neurosurgery & Neurology

Desmoplastic non-infantile ganglioglioma (DNIG) is a rare tumor entity and only a small number of cases have been published until now in the literature. Although its infantile counterpart (desmoplastic infantile ganglioglioma [DIG]) has been already recognized and included together with desmoplastic infantile astrocytoma (DIA) in the WHO Classification of CNS tumors, DNIG has not been accepted as a distinct tumor entity. The reason for this is obviously the scarcity of the neoplasm and subsequently the absence of substantial information regarding its pathogenesis and its association to the infantile form. Herein we present an interesting case with an unremarkable clinical presentation, which came to medical attention after the performance of imaging investigations, for staging purposes of a multifocal papillary thyroid carcinoma. Although the tumor showed the typical biphasic nature, consisting of a solid and a cystic component, its localization in the left ventricular trigonum, was indeed uncommon. Finally, both the histomorphological and the immunohistochemical findings were consistent with the diagnosis of a desmoplastic non-infantile gangioglioma. The occurrence of DNIG with the various clinical manifestations as well as the diverse imaging features, underlines the need of histopathological examination, in order to establish the final diagnosis.
