The angiographic findings in a case of metastatic meningeal carcinomatosis and a case of primary meningeal sarcomatosis are presented. The presence of focal arterial narrowing at the base of the brain and/or over the cerebral convexities, with or without a communicating hydrocephalus, may be the important clues to a diagnosis of diffuse meningeal involvement by tumor. In a patient who presents with bizarre and poorly localizing signs and symptoms, when the cerebrospinal fluid analysis does not fully support a diagnosis of meningitis or subarachnoid hemorrhage, and when there is nothing in the history to suggest drug abuse or a systemic collagen disease, the angiographic findings may point to an unexpected diffuse meningeal tumor.
