Germinoma of the Corpus Callosum

Abstract

A case is described of a young man presenting with diabetes insipidus and a junctional scotoma. A diffuse infiltrating mass centred in the corpus callosum and suprasellar area is found, which on pathological examination proved to be a primary intracranial germinoma. The case illustrates that rarely the corpus callosum can be involved by this tumour and that diagnosis may be delayed in atypical presentations.
