Non-infantile variant of desmoplastic ganglioglioma: a report of 2 cases.

Desmoplastic infantile gangliogliomas (DIGs) are uncommon supratentorial brain tumors with a usually good prognosis despite an aggressive radiological appearance. These tumors form part of a spectrum of desmoplastic infantile tumors that includes desmoplastic infantile astrocytomas. DIGs are classified as benign WHO grade I tumors of infancy. Non-infantile variants of this biologically benign intracranial neoplasm are rare, with only four previous case reports in the literature. We report two cases of non-infantile DIG diagnosed at our institution on the basis of clinical features, radiological appearance and histological findings.
