Desmoplastic Non-Infantile Ganglioglioma; An Incidental Finding with Unusual Localization

The term desmoplastic infantile astrocytoma/ganglioglioma (DIA/DIG) was first introduced by VandenBerg et al. [1] in order to designate a distinct brain tumor, characterized by an early occurrence (usually within the first 4 months of life), voluminous size, intense desmoplasia, divergent astrocytic and ganglionic differentiation and a favorable postoperative course [1]. Although these tumors were thought initially to appear only in infants, after the first publication by Kuchelmeister et al. in 1993, who presented two such neoplasms in older individuals (15 and 25 years of age), it became obvious that they could also arise in other age groups [2]. Therefore, the name desmoplastic non-infantile ganglioglioma (DNIG) has been used to encompass these cases and since then a total of 25 cases has been published [3-8].
