胰腺实性—假乳头状瘤的声像图特征分析

Ultrasonic features of solid pseudopapillary tumor of pancreas

目的探讨超声对胰腺实性-假乳头状瘤(SPTP)的诊断价值。方法分析20例SPTP的超声和病理特点。结果 20例女性SPTP患者,肿瘤均为单发,直径1.5～25.0cm,平均7.9cm;肿瘤位于胰头10例,体尾部6例,尾部3例,占据胰腺大部分1例;15例肿瘤包膜完整,边界清晰,5例肿瘤边界不清晰;11例呈实性类圆形较均匀弱回声,9例呈囊实混合性回声,其中6例以实性结构为主,3例以囊性结构为主;不伴有胆管及胰管扩张。7例肿瘤为恶性,3例肿瘤发生侵袭性生长或肝转移。结论总结SPTP超声特征和了解病理结构有助于提高其诊断水平。

Objective To explore the value of ultrasound in diagnosis of solid pseudopapillary tumor of pancreas （SPTP）. Methods The ultrasonic appearances and pathological datas of 20 cases of SPTP were analyzed. Results All the SPTP patients were female, the lesion was single with the diameter of 1.5- 25.0 cm, and the average diameter of 7.9 cm. The tumor was located in head of pancreas in 10 cases, body of pancreas in 6 cases, tail of pancreas in 3 cases, and most part of pancreas in 1 case. There were 15 cases with clear envelope and boundary, 5 cases with unclear boundary. The tumor showed solid spherical uniform weak echo in 11 cases, while cystic-solid mixed echo in 9 cases, including main solid echo in 6 cases and main cystic echo in 3 cases. There was no dilation of bile duct and pancreatic duct. There were 7 cases with malignant lesions,including 3 cases with invasive growth or hepatic metastasis. Conclusion The ultrasonic appearances of SPTP have some features. By strengthening the awareness of pathological structures, it is helpful in improving its diagnosis level.
