Hepatoid adenocarcinoma of the stomach (HAS) is a rare distinct variant of gastric carcinoma with earlier metastases and worse prognosis compared to the more common intestinal types. It is often misdiagnosed as hepatocellular carcinoma, especially when primary HAS is insignificantly anatomically abnormal, produces high alpha-fetoprotein and develops early liver metastasis. In this case we show the significance of dual-time-point (18)F-fluorodeoxyglucose positron emission tomography (PET)/computed tomography (CT) in accurately diagnosing and staging HAS.
胃肝样腺癌（HAS）是一种罕见的独特胃癌变体，与更常见的肠型胃癌相比，其转移更早且预后更差。它常被误诊为肝细胞癌，尤其是当原发性HAS在解剖学上异常不明显、产生高甲胎蛋白并早期发生肝转移时。在本病例中，我们展示了双时相（18）F-氟脱氧葡萄糖正电子发射断层扫描（PET）/计算机断层扫描（CT）在准确诊断和分期HAS中的意义。
