Primary hepatic carcinoid: A case report and literature review

Figure 1 Abdominal CT scan (July 2005) showing a low-density pseudonodular area (arrow) of 2 cm with biliary dilatation.

Figure 2 Abdominal MRI (August 2005) showing a pseudonodular mass (arrow) measuring about 5 cm × 3 cm of the hepatic segments II-III. At the bottom of the lesion, the biliary tree appears dilated.

Figure 3 111 In-pentetreotide (octreotide) scintigraphy. A: Before hepatectomy: marked hyperactivity of the lesion is observed in the left hepatic lobe and interaortal adenopathy is observed; B: After hepatectomy; abnormal fluid accumulation of ligand in the epigastric region and dishomogeneous hepatic distribution.

Figure 4 Abdominal CT scan. Results of left hepatectomy show an extended nodular mass measuring about 2.5 cm × 1.5 cm arranged on the back part of the caudate lobe, indicating a lymph node localization of disease.
