Fig 5. A 63-year-old man with large cell neuroendocrine carcinoma from the lung.
A, On T2-weighted fast spin-echo image, the solid portion of left occipital lesion (arrow) is hyperintense relative to the normal-appearing white matter. The CNR of the enhancing lesion was 56.
B, On contrast-enhanced T1-weighted image, the posterior part of the lesion is enhanced (arrow). There are multiple enhancing areas (arrowheads) in the left frontal lobe indicative of subacute infarction.
C, On DWI, the solid lesion is hyperintense relative to the normal-appearing cortical gray matter (arrow). The lesion was ranked as grade +2.
D, On ADC map, the solid lesion is hypointense; its nADC was calculated as 1.04.
E, Photomicrograph of the specimen (hematoxylin-eosin stain; original magnification, 40x) shows high cellularity. The tumor cellularity was calculated as 0.51.
