胰腺实性假乳头状瘤的CT及磁共振成像的诊断

目的:研究胰腺实性假乳头状瘤的CT、磁共振成像(MRI)表现,提高对该病的认识诊断水平。方法:2例经手术病理证实的胰腺实性假乳头状瘤均经CT检查,1例行CT增强检查,1例行MRI平扫。回顾性分析其临床特征及CT、MRI表现。结果:2例患者均为年轻女性,无黄疸。2例肿瘤均表现为胰腺区巨大的囊实性肿块。1例肿块内可见钙化,增强后肿瘤的实性部分及包膜可见强化,1例MRI表现为T1、T2均为混杂信号。2例肝内外胆管未见扩张。结论:胰腺SPTP影像学表现有一定的特征。

CT MRI Diagnosis of Solid-pseudopapillary Tumors of the Pancreas

Objective To inverstigate the CT and MRI findings of Solid-pseudopapillary Tumors of Pancreas, and to improve the diagnosis ability of the disease. Methods CT was performed in all 2 patients with Solid-pseudopapillary Tumors of pancreas proved surgically and pathologically . Of all two patients ,enhanced CT was performed in 1 patient,and plain MRI was performed in the other one. Both clinical characteristics and CT and MRI findings were analyzed retrospectively. Results All 2 patients, were young female without jaundice and were found to have giant solid-cystic mass in the area of pancreas. In 1 of 2 patients calcification was found in the mass on CT scan. On enhanced CT and MRI, the wall of cyst and solid portions of the mass showed obvious enhancement. MRI fingds in the patient demonstrated mixed signal intensity on T1 WI and T2WI. No intrahepatic and extrahepatie bile duct dilation was showed in 2 patients. Conclusion The CT and MRI characteristic findings of SPTP might be of great value for the diagnosis.
