胰腺癌是最常见的原发性胰腺恶性肿瘤。症状没有特异性,一般包括腹痛、黄疸、没有食欲、体重减轻、恶心和呕吐。胰腺癌在CT上多表现为边界不清的含实质成分的肿块并伴有胰管的扩张;肿瘤通常较小,没有钙化;在注射造影剂后,肿块显像的强化程度低于周围正常胰腺实质;肿块为卵圆形、圆形或表现为分叶状,多有局部浸润。这些特点有助于胰腺癌和其他胰腺肿瘤的鉴别诊断。
Pancreatic cancer is the most common primary pancreatic malignancy. Symptoms are not specific and generally include abdominal pain, jaundice, loss of appetite, weight loss, nausea and vomiting. Pancreatic cancer often presents with unclear borderline masses with concomitant pancreatic duct enlargement on CT; the tumors are usually small with no calcification; the extent of enhancement of the tumor mass after injection of contrast agent is lower than that of the surrounding normal pancreas Essence; lumps oval, round or lobular lobular performance, and more local infiltration. These features contribute to the differential diagnosis of pancreatic cancer and other pancreatic tumors.
