BACKGROUND
Solid-pseudopapillary tumor of the pancreas is a rather rare but low-grade malignant tumor with good prognosis after surgical excision.
METHODS
In 3 patients with solid-pseudopapillary tumor of the pancreas which were proved pathologically, the imaging features (CT in all and MRI in one patient) of the tumor were analyzed.
RESULTS
In the 3 female patients under 35-year-old who presented no jaundice, CT revealed that huge solid-cystic masses of the pancreatic head with calcification in one and slight dilation of the pancreatic duct in another, but without dilation of the bile duct system in all. MRI demonstrated mixed signal intensity on T1WI and T2WI of the mass in one patient. CT and MRI revealed obvious enhancement of the cystic wall and solid part of the masses.
CONCLUSIONS
CT and MRI findings of solid-pseudopapillary tumor of the pancreas are characteristic, and the diagnosis can be made preoperatively with the combination of clinical features.
背景
胰腺实性假乳头状肿瘤是一种较为罕见但恶性程度较低的肿瘤，手术切除后预后良好。
方法
对3例经病理证实的胰腺实性假乳头状肿瘤患者的肿瘤影像学特征（全部行CT检查，1例患者行MRI检查）进行分析。
结果
3例35岁以下女性患者均无黄疸，CT显示胰头巨大实性囊性肿块，1例有钙化，另1例胰管轻度扩张，但均无胆管系统扩张。1例患者MRI显示肿块在T1WI和T2WI上呈混合信号强度。CT和MRI显示肿块的囊壁和实性部分明显强化。
结论
胰腺实性假乳头状肿瘤的CT和MRI表现具有特征性，结合临床特征可在术前作出诊断。
