[Diffuse meningeal melanoma].
Diffuse leptomeningeal melanoma is an uncommon condition; its diagnosis is difficult, and requires the detection of atypical melanic cells in the CSF or the performance of meningeal biopsy. We report a 34-year-old patient with progressive symptoms of intracranial hypertension of 2 months duration, in whom meningeal biopsy was required for a definitive diagnosis. The patient's age, the neuropathological abnormalities and the images of computed tomography scan (CT), and also a through clinical and paraclinical investigation, led us to the conclusion that the patient had diffuse primary leptomeningeal melanoma.
