Cerebellar calcification in central neurofibromatosis: CT in two cases.

Manifestations of central von Recklinghausen 's neurofibromatosis are well known and may include bilateral acoustic neuromas in the absence of peripheral neurofibromatosis or associated gliomas, meningiomas, other cranial nerve neuromas, optic nerve gliomas, and ependymomas [1]. A few reports deal specifically with the cranial CT findings in central neurofibromatosis [2-4]. One series [3] includes a case with cerebellar calcification unassociated with a mass lesion. We report two additional cases of central neurofibromatosis, both of which exhibited bilateral acoustic neuromas and nonneoplastic calcification in the cerebellar hemispheres on CT.
