F. Ebinger et al., Early diffuse leptomeningeal primitive neuroectodermal tumors can escape detection by magnetic resonance imaging, CHILD NERV, 16(7), 2000, pp. 398-401
Primitive neuroectodermal tumors are easily detected by neuroradiologic ima
ging, as a rule. We report on two patients with early diffuse leptomeningea
l primitive neuroectodermal tumors which escaped detection by contrast-enha
nced magnetic resonance imaging.
