Intracranial calcified deposits in neurofibromatosis type 2. A CT study of 11 cases.

CT examinations of 11 consecutive patients with neurofibromatosis type 2 (NF-2) revealed non-tumoral intracranial calcified deposits in seven cases. Abnormal calcification of the choroid plexus was found in six cases. Calcification in the cerebellar hemispheres was observed in four cases. In two cases nodular calcifications on the surface of the cerebral hemispheres were detected. Our findings and the data in the literature show that non-tumoral calcifications of different locations can be regarded as part of the NF-2 syndrome.
