A non-infantile case of desmoplastic infantile astrocytoma

Case report: We describe a very rare non-infantile case of desmoplastic infantile astrocytoma (DIA). A 9-year-old boy presented with motor weakness and sensory disturbance in his right upper and lower limbs. CT and MRI showed a contrast-enhanced large cystic tumor in the left sensorimotor area. We successfully resected the entire tumor. Its histopathological features were typical of DIA. Outcome: The patient's neurological symptoms improved postoperatively. Neither radiotherapy nor chemotherapy was used postoperatively. The patient developed normally and had been doing well for 12 months after surgery without tumor recurrence.
