Cranial CT of neurofibromatosis.

The results of computed tomography (CT) of the orbits and brain of 29 patients with neurofibromatosis were reviewed to determine the contribution of CT scanning to the diagnosis of this disorder. In the presence of orbital symptoms, CT confirmed the presence of suspected lesions such as optic nerve gliomas, demonstrated asymptomatic and atypical lesions, and displayed concomitant intracranial involvement of the optic chiasm. CT of the brain revealed a multiplicity of abnormalities such as astrocytomas, intracerebral calcification, hydrocephalus, and congenital lesions.
