Liver metastasis from pancreatic neuroendocrine tumor: A case report

Figure 4 Contrast-enhanced abdominal magnetic resonance imaging revealing a hepatic lesion in the left lobe characterized by hypointense T1-weighted and hyperintense T2-weighted signals with mildly increased diffusion-weighted imaging signal intensity. A: Magnetic resonance imaging (MRI) T1 with contrast enhancement (arrow); B: MRI T2 with contrast enhancement (arrow); C: MRI diffusion-weighted imaging with contrast enhancement (arrow); D: Venous phase magnetic resonance imaging (arrow). The lesion measured approximately 2.4 cm × 3.3 cm and demonstrated ring-like enhancement after contrast administration. Intrahepatic vessels were normal, with no dilation of the intrahepatic or extrahepatic bile ducts.
