中文摘要：目的探讨胰腺实性假乳头状瘤（SPTP）的螺旋CT表现特征。方法回顾性分析经手术及病理证实的34例胰腺实性假乳头状瘤的螺旋CT表现，并与病理结果进行对照。结果34例患者中女30例，男4例。肿瘤位于胰尾14例，胰头11例，胰体6例，胰颈3例。肿瘤最大径2.0～20.0 cm，平均6.5 cm。囊实性肿块29例，CT值12.6～21.3 HU；实性肿块5例，CT值24.5～42.8 HU；包膜完整24例，包膜不完整10例；伴有钙化15例，伴出血13例，伴肝脏转移2例。动态增强显示实性部分和包膜呈渐进性强化，且动脉期轻度强化，CT值30.1～43.6 HU；门静脉期中度强化，CT值41.2～68.9 HU；延迟期持续强化，CT值48.2～63.8HU。结论增强扫描实质部分呈渐进性强化是胰腺实性假乳头状瘤特征性的螺旋CT表现。

外文摘要：Objective To investigate the spiral CT features of solid pseudopapillary tumor of pancreas （SPTP）. Methods Spiral CT features of 34 SPTP cases confirmed by surgery and pathology were analyzed retrospectively. Results There were 30 females and 4 males. Tumors located in the tail, head, body and neck of the pancreas were respectively in 14, 11, 6 and 3 cases. The maximum diameter was 2. 0 - 20. 0 cm, with an average of 6.5 cm. There were 29 cases of solid-cystic mass with a CT value of 12. 6 - 21.3 HU and 5 cases of solid mass with a CT value of 24. 5 -42. 8 HU; Complete capsule were observed in 24 cases, while incomplete capsule were observed in 10 cases; 15 cases were found with tumor calcification, 13 with hemorrhage and 2 cases with liver metastasis. After dynamic enhancement, the solid part and capsule showed progressive and slight enhancement in the arterial phase with a CT value of 30. 1 - 43.6 HU, and slight enhancement in portal phase with a CT value of 41.2 -68.9 HU, and persistent enhancement in delayed phase with a CT value of 48.2 - 63.8 HU. Conclusions Spiral CT features of SPTP are characterized by progressive enhancement of solid mass in enhanced scan.
