From: Colorectal liver metastases: radiopathological correlation
Typical CT appearance of non-otherwise specific (NOS) adenocarcinoma liver metastasis in a 41-year-old female patient. Contrast enhanced CT image obtained during hepatic arterial phase (a) shows a 33 mm lesion in the left liver lobe with peripheral rim enhancement (arrow) and a hypoattenuating central area (star). Histological analysis (b) confirmed the presence of diffuse central acinar necrosis (stars) in the central part of the lesion. Note the proliferative peripheral tumor cells corresponding to the enhancing rim on CT image (a, b arrows)
