Comparison of clinical, imaging, and histopathologic characteristics of PLNTYs and oligodendrogliomas
PLNTY Oligodendroglioma
Age at diagnosis (yr) 16–18 40–60
Most common location Temporal lobe Frontal lobe
Tumoral border Well-circumscribed Poorly defined
Calcification Heavily calcified, central location of calcifications Less prominent; calcifications are classically gyriform
Intralesional signal Heterogeneous Heterogeneous
Enhancement Minority of tumors, typically mild Minority of tumors, typically mild (described as dotlike)
Intratumoral cysts ∼90% ∼50%
