Targeted gene sequencing and bioinformatics analysis of patients with gallbladder neuroendocrine carcinoma: A case report

Figure 1 Abdominal contrast-enhanced computed tomography scan reveals a 7 cm mass in liver segments IVb and V, with localized thickening of the gallbladder fundus wall and early-stage enhancement followed by a prolonged contrast effect. A: Arterial phase showed inhomogeneous lesion enhancement; B: The portal venous phase showed a prolonged contrast effect in the mass; C: The delayed phase showed progressive enhancement of the mass; D: The mass invades liver segments IVb and V.
