Primitive neuroectodermal tumors of the spine: a comprehensive review with illustrative clinical cases.
Primary spinal primitive neuroectodermal tumors (PNETs) are uncommon malignancies that are increasingly reported in the literature.

Because no standard management guidelines exist for treating these tumors, ...

متن کاملComputed tomography of primitive neuroectodermal tumors.
The primitive neuroectodermal tumor is a neoplasm of young individuals that occurs predominantly in the supratentorial compartment. It appears on computed tomography as a bulky mass, often with calcification with predominantly homogeneous enhancement but on occasion with cystic or necrotic areas. Cerebrospinal fluid seeding was observed in more than half the cases in our series. The patients ha...
متن کاملSupratentorial primitive neuroectodermal tumors in young children.

Although stPNET are undoubtedly aggressive brain tumors and results of treatments are still disappoin...
