UNASSIGNED:分析胃肝样腺癌(HAS)的CT表现,提高该病的诊断准确性。
UNASSIGNED:回顾性分析22例经病理证实的HAS患者的CT图像。我们调查了病变的位置,形态学,增强功能,侵入周围器官的区域,淋巴结转移,和静脉肿瘤血栓。
未经评估:在22名患者中(17名男性和5名女性,平均年龄为61.41±9.83岁,范围为36至80岁)。肿瘤的形态包括肿块(n=5),局灶性溃疡(n=7),和浸润性溃疡(n=10)。12例癌外脂肪侵入。增强扫描在所有情况下显示持续增强。未增强扫描的CT值,动脉期,门静脉期为30.36±6.46、60.91±17.80和75.64±22.09(亨氏单位,HU),分别。在六个案例中,肿瘤浸润周围器官:肝脏(n=1),胰腺(n=2),肝脏和胰腺(n=3)。22名患者中有16名(72.3%)病理标本证实了CT成像的可疑淋巴结转移。肝内转移14例。7例患者有静脉癌栓:3例患者在门静脉的主干和肝内分支发展了癌栓,2例患者在门静脉,脾静脉,同时肠系膜上静脉。
未经证实:HAS的CT扫描通常显示胃壁增厚和浸润性溃疡。经常可以看到渗入鞘外脂肪。增强扫描显示病变的连续和渐进增强。淋巴结转移,肝内转移,门静脉癌栓在HAS患者中很常见。
UNASSIGNED: To analyze the CT findings of hepatoid adenocarcinoma of the stomach (HAS) and improve the diagnosis accuracy of this condition.
UNASSIGNED: The CT images of 22 pathologically confirmed HAS patients were analyzed retrospectively. We investigated the location of lesions, morphology, enhancement features, area of invasion into surrounding organs, lymph node metastasis, and venous tumor thrombus.
UNASSIGNED: Among the 22 patients (17 men and 5 women, the mean age was 61.41 ± 9.83 years ranging from 36 to 80 years) with HAS; the morphology of tumors included mass (n = 5), focal ulcer (n = 7), and infiltrating ulcer (n = 10). Extraserous fat was invaded in 12 cases. Enhancement scans showed continuous enhancement in all cases. The CT values of unenhanced scan, the arterial phase, and the portal venous phase are 30.36 ± 6.46, 60.91 ± 17.80, and 75.64 ± 22.09 (Hounsfield Unit, HU), respectively. In six cases, the tumor infiltrated the surrounding organs: liver (n = 1), pancreas (n = 2), and both liver and pancreas (n = 3). In 16 out of 22 patients (72.3%), suspicious lymph node metastasis at CT imaging has then been confirmed by pathological specimens. Intrahepatic metastasis was found in 14 cases. Seven patients had venous tumor thrombus: three patients developed tumor thrombus in the main trunk and intrahepatic branches of the portal vein and two patients in the portal vein, splenic vein, and superior mesenteric vein simultaneously.
UNASSIGNED: The CT scans of HAS often show a thickened gastric wall and infiltrating ulceration. Infiltration into extraserosal fat is often seen. Enhancement scans show a continuous and progressive enhancement of lesions. Lymph node metastasis, intrahepatic metastasis, and portal vein tumor thrombus are common in HAS patients.
