胰腺實(shí)性假乳頭狀瘤的MSCT診斷價(jià)值
[Abstract]:Objective to study the multilayer spiral CT (multislice spiral CT,MSCT findings of solid pseudopapillary tumors of the pancreas (solid-pseudopapillary tumors of the pancreas,SPTP) and to explore the relationship between SPTP tumors and surrounding vessels by post-processing MSCT images. And the clinical application value of the relationship between tumor and surrounding tissues. Methods the imaging data of 34 cases of SPTP confirmed by operation and pathology were retrospectively analyzed, including CT findings, tumor and peripheral tissues, and the relationship between adjacent blood vessels. Results all 34 cases were single tumors, including 16 cases of pancreatic head (47.1%), 2 cases of neck (5.9%), 1 case of head and neck (2.9%), 5 cases of body (14.7%), 4 cases of tail (11.8%). There were 4 cases (11.8%) in the body and tail, 2 cases (5.9%) in the uncinate process, 15 cases (44.1%) in the solid, 7 cases (20.6%) in the cystic, 12 cases (35.3%) in the cyst. In the remaining 33 cases, the lesions presented as capsule, solid partial or septal continuous enhancement, and partial consolidation as cloud flocculent uneven enhancement. MSCT postprocessing technique showed that 6 cases had adhesion and infiltration with adjacent blood vessels. 1 case had adhesion with adjacent tissues and organs, the boundary was not clear, and 1 case had incomplete capsule. The diagnosis of MSCT before operation was consistent with that of intraoperative and postoperative pathology. Conclusion MSCT can make a correct diagnosis of SPTP before operation. MSCT post-processing technique can clearly show the relationship between tumor and peripheral blood vessels and tissues. It has a high clinical guiding value for the evaluation of tumor resectability.
