Radiologic evaluation of neurosarcoidosis: role of computed tomography.

Radiologic evaluation of 15 patients with central nervous system sarcoidosis is reported together with a review of the literature. The hydrocephalus that is often associated is discussed in relation to known pathogenetic aspects of the disease process. Intracranial sarcoid mass lesions, formerly thought to be a very rare manifestation of this disease, have been seen more often since the advent of computed tomography. Computed tomography may contribute to a more prompt recognition of the diagnosis and help to avoid the considerable morbidity that can occur in some patients with progression of the disease within the central nervous system .
