Ganglioglioma

Discussion:

This case illustrates the differential of a temporal lobe tumor. In this case the presence of a vividly enhancing nodule favors either a ganglioglioma (the diagnosis in this case) or a pleomorphic xanthoastrocytoma. (see this companion case)

DNETs usually do not enhance this vividly and usually have a bubbly appearance. Although pilocytic astrocytomas can have this appearance, they usually have a cystic component, are usually found in younger patients and the temporal lobe is not a characteristic location.
