复习18例经病理学、细胞学或诊断性治疗证实的胰腺转移瘤病人的超声诊断。在声像图上,肿瘤通常表现为低回声,后方回声无变化或增强,边界较清楚但不规则,胰头病灶可导致胆总管和胰管的扩张;邻近血管受压、显示不清或消失,或肿物与血管的分界不清。胰腺转移瘤虽然较为少见,但早期发现较难。在与原发性胰腺癌进行鉴别时,应结合病人原发肿瘤的存在,肿块边界清楚,行超声引导针吸活检,从而作出正确的诊断。
A review of ultrasound diagnosis of 18 cases of pancreatic metastases confirmed by pathology, cytology, or diagnostic treatment. In acoustic imaging, the tumor usually shows a low echo, no change or enhancement of the posterior echo, a clearer but irregular border, pancreatic head lesions can cause expansion of the common bile duct and pancreatic duct; adjacent blood vessels are compressed, appear unclear or disappear Or the boundary between the tumor and the blood vessel is not clear. Although pancreatic metastases are rare, early detection is difficult. In the identification with primary pancreatic cancer, the patient should be combined with the presence of primary tumors, the mass boundaries should be clear, and ultrasound-guided needle biopsy should be performed to make a correct diagnosis.
