An MRI showed extensive multifocal abnormal signaling in the gray matter, white matter, epencephalon
, and brainstem [Figure 1]e, however, CSF was normal.
Whole brains from adult carp were dissected and five parts of the brain (telencephalon, diencephalon, mesencephalon, epencephalon
and macromyelon) were carefully separated.
A foreign study suggests that, PCNSL frequently occurs in cerebral hemisphere, callosum, basal ganglia and thalamus, less frequently occurs in epencephalon
and brainstem and seldom occurs in ventricle only; 87% of PCNSL is supratentorial lesion.
