Supratentorial primitive neuroectodermal tumour (PNET)

Case contributed by Dr Jeremy Jones

Presentation

Child presenting with right sided neurological symptoms and a skull mass.

Large heterogenous mass of the left cerebral hemisphere, centered in the frontoparietal region. It has cystic / necrotic components with extensive blooming on T2* weighted sequence consistent with blood products. Extensive vasogenic-tumour oedema spreads particularly anteriorly into the frontal lobe, with significant midline shift. 

The mass extends directly through the skull vault and into the subgaleal tissues. 

Case Discussion

Features are consistent with the subsequently confirmed supratentorial PNET.
