case_images: The pathological diagnosis was multiple gastric carcinoid tumors with lymph node metastasis (T1N1M0, pStage IIIB) and normal gall bladder (Fig. 1).
case_images: Gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging.. A mass showing low intensity and measuring 17 mm was noted on T1-weighted image (a). The dynamic study showed gradual enhancement (b: 30 s. c: 180 s. d: hepatocyte phase). The mass showed high intensity on T2-weighted image (e) and diffusion-weighted image (f).

case_images: After 2 years, enhanced abdominal computed tomography (CT) revealed a novel lesion in S5 of the liver with ring enhancement measuring 22 x 15 mm (Fig. 2).
case_images: Macroscopic findings.. A well-marginated nodular lesion with mixture of whitish and reddish region measuring 15 x 11 x 19 mm was noted.

case_images: The resected specimen showed a 15 x 11 x 19 mm well-marginated nodular lesion with a mixture of whitish and reddish regions (Fig. 3).
case_images: Histopathological findings.. A fibrous lesion with collagenous stroma replacing hepatocytes was noted. Lack of cellular component and edematous tissue with micro-bleeding was observed. Dilated vessels were dispersed in the lesion (a: HE. x 20. b: HE. x 100). Immunohistochemistry showed CD34 positive endothelium, indicating dilated vessels in the lesion (c: HE. x 20. d: x100).
