<br/><br/> Detection of leptomeningeal metastases is fundamental to a complete evaluation of central nervous system (CNS) or non-CNS tumor with suspected involvement of the neuroaxis.The goal is to assess the appearances of different magnetic resonance (MR) sequences in the diagnosis of leptomeningeal metastases and correlate those positive findings with the cerebral spinal fluid (CSF) cytology results.Contrast-enhanced MR imaging can be invaluable, detecting the false-negative lumbar punctures. FLAIR and diffusion images can be helpful in diagnosing leptomeningeal metastases of non-enhancing primary tumors.Prognosis was more related to the primary tumor type than to the leptomeningeal enhancement MR pattern
