Desmoplastic infantile ganglioglioma (World Health Organization grade I) is a rare neoplasm. Despite their common large size and spectacular radiologic and histologic features, the prognosis after surgical resection is good. We present a new case of this tumor in a 14-month-old boy with a recent history of intracranial hypertension. Magnetic resonance imaging revealed a large tumor involving the left collateral trigone with dilatation of the lateral ventricles. Surgery revealed two separate solid tumors: one in the left falco-tentorial region and the other in the left rolandic area. Microscopic examination showed a proliferation of neoplastic astrocytes in reticulin-rich desmoplastic stroma associated with scattered ganglion cells. One year after surgery follow-up magnetic resonance imaging did not show tumor progression.

Desmoplastic infantile gangliogliomas (DIGs) are rare supratentorial tumors that arise in infancy. Despite the large size of these lesions, the prognosis is generally considered favorable after gross-total resection (GTR); however, in incidental cases tumor progression has been described. The authors report on a child harboring a DIG with a high-grade primitive cell population and glial differentiation. The progressive clinical course was determined by this cell component in spite of GTR and adjuvant chemotherapy. The significance of the presence of a high-grade primitive tumor component in the context of DIG is discussed.
