目的总结胰腺体尾部癌的影像学表现。方法对经手术及病理证实的23例胰腺体尾部癌的影像学资料进行分析,包括肿瘤的部位、大小、形态、质地、强化方式和与周围结构的关系。其中5例患者行MRI增强扫描,18例患者行螺旋CT增强扫描。结果 23例患者中,病灶位于体部5例,尾部7例,体尾部11例。CT表现为胰腺体尾部实质内不规则肿块,密度稍低,混杂不均;MRI肿块表现为T1WI略低或低信号,T2WI为略高或混杂信号。19例增强后不均匀轻度强化,4例增强后强化不明显。5例边界清晰,18例边界模糊。16例出现周围淋巴结转移,8例周围血管受累。3例出现脏器及骨转移。结论胰腺体尾部癌具有一定的影像学特征,CT和MRI扫描可以充分反映肿块的形态、血供特点及周围蔓延情况。
Objective To summarize the imaging findings of pancreatic tail body cancer. Methods The imaging data of 23 cases of pancreatic body tail carcinoma confirmed by operation and pathology were analyzed, including the location, size, shape, texture, enhancement of the tumor and the relationship with the surrounding structures. Among them, 5 patients underwent MRI enhanced scan and 18 patients underwent spiral CT enhanced scan. Results Among the 23 patients, 5 were located in the body, 7 in the tail and 11 in the body. CT showed irregular mass in the tail of the pancreas with slightly lower density and heterogeneous heterogeneity. MRI showed slightly lower or lower signal of T1WI and slightly higher or mixed signal of T2WI. 19 cases of non-uniform mild enhancement, 4 cases of enhanced enhancement was not obvious. 5 cases of clear boundaries, 18 cases of border blurred. 16 cases of peripheral lymph node metastasis, peripheral vascular involvement in 8 cases. 3 cases of organ and bone metastases. Conclusion The pancreatic body tail carcinoma has some imaging features. The CT and MRI scans can fully reflect the shape of tumor, the characteristics of blood supply and the surrounding spread.
