Fig 3. A 41-year-old man with a poorly differentiated adenocarcinoma from the lung.

A, T2-weighted fast spin-echo image shows a left parietal subcortical lesion (arrow). It is slightly hyperintense relative to the normal-appearing white matter. The CNR of the solid lesion was 32.

B, On contract-enhanced T1-weighted image, the lesion is well enhanced (arrow).

C, On DWI, the lesion is slightly hyperintense relative to the normal-appearing cortical gray matter (arrow). It was graded as +1.

D, On ADC map, the nADC of the lesion was calculated as 1.45.

E, Photomicrograph of the specimen (hematoxylin-eosin stain; original magnification, 40x) shows higher cellularity than Fig 2E. Tumor cellularity was calculated as 0.334.
