Carcinomatous meningitis in a 67-year-old woman with stage IV non-small cell lung cancer. Coronal (a) and sagittal (b, c) T1-weighted MR images after intravenous gadolinium contrast administration demonstrate diffuse, nodular leptomeningeal enhancement involving both cerebral hemispheres, but more markedly along the tentorium and into the subarachnoid spaces between the cerebellar folia (yellow arrows)
