We describe the computed tomography (CT) imaging findings in six cases (five males and one female; age range 61-78 years; mean age 67.3 years) with histologically proven hepatoid adenocarcinoma of the stomach (HAS). Five of the six patients had elevated serum alpha-fetoprotein levels. The most common type of gross appearance HAS on CT is a polypoid mass (83%, 5/6). The most common contrast enhancement pattern was heterogeneous. All six patients had a regional lymphadenopathy larger than 6 mm in its short axis. Liver metastases (n = 3) were noted. Venous tumor thrombosis was identified in the portal vein (n = 2) of the regions near primary gastric tumors or metastatic masses. Our findings suggest in an elderly, male patients with a large heterogeneous enhancement tumor, the presence of distant metastases, regional lymphadenopathy and characteristically increased serum alpha-fetoprotein levels indicates a high likelihood of HAS.
