To analyze the patterns of MRI manifestation, and to investigate the value of MRI in diagnosis of meningeal carcinomatosis. Twenty three cases with meningeal carcinomtosis were analyzed. All cases had pre- and post- contrast MR imagings, typical clinical symptoms and/or positive CSF examination. Of the 23 cases, 22 had abnormal post-contrast meningeal enhancement. The remaining case had hydrocephalus without any enhancement. There were four abnormal MRI patterns: (1)total meningeal enhancement, (2) smooth or nodular enhancement of parts of the meninge, (3)subependymal enhancement, (4)hydrocephalus only. MRI is an important assistant method in diagnosis of meningeal carcinomatosis. Post-contrast MRI is mandatory.
