In this study, we evaluated the CT findings of patients with hepatoid adenocarcinoma of the stomach.
The CT scans of eight patients (seven males and one female; age range 44-70 years; mean age 59 years) with histologically proven hepatoid adenocarcinoma of the stomach were retrospectively evaluated by two radiologists in consensus. Scans were evaluated for gastric wall thickening, involved site enhancement, adjacent organ invasion, lymphadenopathy, distant metastases, and venous tumor thrombosis.
Tumors appeared as eccentric wall thickening (n = 8) and heterogeneous enhancement (n = 7). Adjacent organ invasions were noted to liver (n = 3), pancreas (n = 2), and esophagus (n = 1). All eight patients had a regional lymphadenopathy larger than 8 mm in its short axis. Distant metastases (liver, n = 4; non-regional lymph node, n = 1) were also noted. Venous tumor thrombosis was identified in the portal vein (n = 3), splenic vein (n = 1), main portal vein (n = 1), or right gastroepiploic vein (n = 1) in the regions near primary gastric tumors or metastatic masses.
On CT scans, hepatoid adenocarcinoma of the stomach appears as an eccentric gastric wall thickening and shows a strong tendency for liver and lymph node metastasis and venous invasion around the primary gastric tumor or a metastatic hepatic mass.
在本研究中，我们评估了胃肝样腺癌患者的CT表现。
对8例经组织学证实为胃肝样腺癌的患者（7例男性，1例女性；年龄范围44 - 70岁；平均年龄59岁）的CT扫描图像进行回顾性分析，由两名放射科医生达成共识后进行评估。评估内容包括胃壁增厚、受累部位强化、邻近器官侵犯、淋巴结肿大、远处转移及静脉瘤栓形成。
肿瘤表现为偏心性胃壁增厚（n = 8）和不均匀强化（n = 7）。发现有3例侵犯肝脏、2例侵犯胰腺、1例侵犯食管。所有8例患者均有短径大于8 mm的区域淋巴结肿大。还发现有远处转移（肝脏转移4例；非区域淋巴结转移1例）。在原发性胃肿瘤或转移灶附近区域的门静脉（n = 3）、脾静脉（n = 1）、门静脉主干（n = 1）或胃网膜右静脉（n = 1）中发现静脉瘤栓形成。
在CT扫描中，胃肝样腺癌表现为偏心性胃壁增厚，并且在原发性胃肿瘤或转移性肝肿块周围有强烈的肝转移、淋巴结转移及静脉侵犯倾向。
