title: Early diffuse leptomeningeal primitive neuroectodermal tumors can escape detection by magnetic resonance imaging.
abstract: Primitive neuroectodermal tumors are easily detected by neuroradiologic imaging, as a rule. We report on two patients with early diffuse leptomeningeal primitive neuroectodermal tumors which escaped detection by contrast-enhanced magnetic resonance imaging.
