| 目的 观察儿童胰腺实性假乳头状瘤（SPTP）超声表现。方法 回顾性分析10例SPTP患儿，男2例、女8例，年龄7~13岁、中位年龄11岁；均为单发病灶，4例位于胰头、6例位于胰体尾，最大径30~130 mm，中位最大径53 mm，观察其超声表现。结果 超声显示10例SPTP边界均清晰，呈圆形或类圆形，形态尚规整，其中8例具有完整包膜；2例内部回声呈实性、8例呈囊实性；5例见囊内出血，6例钙化均以边缘钙化为主。CDFI于肿瘤实性成分内探及少许血流信号，囊性成分内未见明显血流信号。10例均未见明显胰管、胆管梗阻或扩张，无周围侵犯或转移；2例肿瘤包膜破裂出血，可见大量血性腹腔积液，1例胰源性门脉高压见胃底静脉纡曲扩张。结论 儿童SPTP超声表现具有特征性，结合临床所见有助于确诊。 |

| Objective To observe the ultrasonic manifestations of solid pseudopapillary tumor of the pancreas (SPTP) in children. Methods Data of 10 children with single SPTP, including 2 males and 8 females, aged 7 to 13 years, with a median age of 11 years were retrospectively analyzed. SPTP located in the head of pancreas in 4 cases and in the body or tail of pancreas in 6 cases, with the maximum diameter of 30-130 mm and the median maximum diameter of 53 mm. Ultrasonic manifestations of SPTP were observed. Results Ultrasound showed that the boundaries of 10 SPTP were all clear, with roughly regular round or quasi-circular shape, and the capsule was intact in 8 case, solid internal echo in 2 cases and cystic solid internal echo in 8 cases. Intracapsular hemorrhage of SPTP was detected in 5 cases, while mainly marginal calcification was found in 6 cases. CDFI showed a little blood flow signals in the solid component of tumor, while no obvious blood flow signal was observed in the cystic component. No obvious obstruction nor expansion of pancreatic duct or bile duct was found in all 10 cases, no invasion nor metastasis was noticed. Tumor capsule rupture and hemorrhage were observed in 2 cases with massive bloody ascites, while 1 case was found with pancreatogenic portal hypertension and tortuous expansion of gastric fundus vein. Conclusion Ultrasonic manifestations of SPTP in children were characteristic, which were helpful for diagnosis of SPTP combined with clinical findings. |
