[Magnetic resonance imaging features of desmoplastic cerebral ganglioglioma of infancy: report of 1 case]

Desmoplastic infantile ganglioglioma is a rare intracranial tumor of infancy, characterized by solid and cystic component, voluminous size and supratentorial location. These tumors are diagnosed usually below the age of 2 years. We report 1 case of desmoplastic ganglioglioma in 13-year-old male. Computed tomography and magnetic resonance imaging diagnosed supratentorial mixed cystic and solid tumor, which presented as a large cystic component with intense contrast enhancement of a mural nodule. The tumor was surgically removed, and histology revealed desmoplastic ganglioglioma. The patient had a good follow up. This observation emphasizes the possibility of desmoplastic ganglioglioma in older infants. It mustn't be considered as a specific entity of very young age infant and must be recognized in older infant because it may be misdiagnosed as malignant glioma. Despite the pseudo malignant appearance, these tumors have a good prognosis after surgery and when excision is complete they don't led to recurrences.
