Ultrastructural study of a cerebral gangliocytoma.
A pure cerebral gangliocytoma leaving no sign or symptom of recurrence after surgical removal is reported, with special reference to its CT scan and the ultrastructural findings. Unusual, large, dense bodies having the size of 800-1200 m mu and radiating from a central core were identified on the ultrastructural study. Microcystic formations might have been produced by active secretory granules containing dense core vesicles. The literature concerning the dense core vesicle of ganglion cell tumors is reviewed.
