Abstract

Two cases of ganglioglioma are presented. One, arising in the right cerebellar vermis of 14 year old girl, showed an ill-defined low density area on CT scan. The tumor was partly cystic and was excised. She was free of symptoms for 2 years and 3 months The other case, 17 year old girl, had a cystic lesion with a mural nodule in the left cerebral hemisphere. Cystic astrocytoma was the clinical impression. The mural nodule was excised. Histologic features of both tumors consisted of neoplastic ganglion cells in groups or singly in the background of fibrillary astrocytes. The cellularity was variable in areas, and cystic degeneration and calcification were common features. Ganglioglioma is the tumor of childhood and adolescence and gives a slow clinical course.
