Sugar coating is an imagery metaphor for lepto-meningeal carcinomatosis. This carcinomatosis is related to the meningeal
dissemination of a solid tumor lesion or blood disease. Call signs are nonspecific. We report a case of lepto-meningeal carcinomatosis
in a 51-year-old patient who was followed for treated breast cancer. We discuss the description of this semiological sign, its
pathophysiology and the characteristic signs in imaging of lepto-meningeal carcinomatosis.
