[Hodgkin's granuloma of the cerebral hemisphere. Apropos of one case]

With reference to a case of Hodgkin's granuloma of the frontal lobe, a review of the literature has enabled 8 similar cases of intra-cerebral localisation of this disease to be reclassified. Their mechanism is discussed on the basis of neuropathological data and in particular their development in situ. Excision of the lesion appears to be the treatment of choice.
