title: [The value of MRI in a case of cerebro-meningeal miliary carcinomatosis of melanotic origin].
abstract: Despite the frequency of cerebral metastases from melanoma, there have been very few papers on this subject in the radiological literature. We report one such case, original by its disseminated carcinomatosis appearance and by the disassociation between computed tomography and magnetic resonance imaging, illustrating the greater sensitivity of the latter examination. In view of the fact that 11 to 13% of patients with a cerebral metastasis from melanoma are asymptomatic, there may be a place for screening of these patients by MR imaging. The association of neurological lesions and cutaneous naevi raises the problem of neurocutaneous melanosis (degenerating phakomatosis).
