title: Gadolinium-enhanced magnetic resonance imaging of meningeal carcinomatosis in colon cancer.
abstract: Meningeal carcinomatosis has been infrequently reported in colorectal carcinoma. Recently the value of gadolinium-enhanced magnetic resonance imaging (MRI) in the examination of this disease has been described. We report a 55-year-old man with meningeal carcinomatosis from a known colon cancer. In this case, a gadolinium-enhanced MRI of the brain showed enhancing dura and nodular lesions which were not detected by enhanced computed tomography. The gadolinium-enhanced MRI may serve as an indicator of leptomeningeal involvement and may be a useful test in addition to the evaluation of cerebrospinal fluid cytology and chemistry.
