SYN: ganglioma. [ganglion + G. neuron, nerve, + -oma, tumor]
- central g. SYN: gangliocytoma.
- dumbbell g. a g. in which the gross configuration resembles a dumbbell, e.g., two spheroidal masses connected by a narrow portion, usually the result of the neoplasm being somewhat molded by a resistant structure such as two ribs.
