J Neurosurg. 1996 Jun;84(6):1051-4. doi: 10.3171/jns.1996.84.6.1051.


Extranodal sinus histiocytosis with massive lymphadenopathy involving the meninges is a rare clinical entity. The authors describe the unusual case of an occipital meningeal lesion in a 25-year-old man in whom they found inflammation of the occipital lobe mimicking lymphoplasmacyte-rich meningioma. The clinical similarities and differences are discussed.
