Abstract
Background Desmoplastic infantile gangliogliomas are rare intracranial tumors that mostly occur in the first 2 years of life. They are exclusively supratentorial, generally have a voluminous size, and are partially cystic. Histologically they are characterized by a divergent astrocytic and ganglionic differentiation and a prominent desmoplastic stroma; more primitive cells may be observed, which present a higher number of mitoses and these areas can mimic the features of malignant astrocytomas. Surgery is the treatment of choice. Data available from the literature suggest that no complimentary treatment is needed in cases of complete tumor resection. Chemotherapy is an option in infants with infiltration of eloquent CNS structures and progressive disease after surgery. DIGs have generally a good prognosis: recurrence-free intervals of up to 14 years have been reported and spontaneous disappearance of tumor residuals has also been described.
