Angiocentric glioma, a recently added WHO grade-I tumor
نویسندگان
چکیده
Angiocentric glioma (AG) is a distinct group of tumors, grade I according to the 2007 WHO classification of tumors of the central nervous system. It is a rare group predominantly seen in children and young adults, with good prognosis following gross total resection. A young child presented with progressively worsening seizure activity; MRI revealed a lesion involving the left posterior frontal lobe. The lesion was surgically resected, and the child is now free of seizure medications, with good neurological function.
