Solid-pseudo papillary neoplasms of pancreas (SPNP) are rare in men and are often misdiagnosed. This study aimed to analyze the clinical and multi-slice computer tomography (MSCT) features of patients with SPNP, and examine the differences between males and females. In this retrospective cohort study, the clinical and imaging data of 29 patients with histolopathologically confirmed SPNP (seven males and 22 females) that underwent radical resection, and underwent preoperative MSCT at the First People’s Hospital of Lianyungang between August 2010 and December 2018 were collected. All MSCT images were reviewed by two radiologists; disagreements were ruled by a third one. The median age of the 29 patients with SPNP was 30 (range, 12–70) years. The male patients were older than the female patients [median, 56 (28–66) vs. 29 (12–70), P = 0.012]. The median tumor size was 3.9 (range, 2.0–6.4) cm in the male SPNP patients, which was significantly lower than the 7.0 (range, 4.6–14.6) cm in the female patients (P < 0.001). The calcification rate of the SPNP was significantly higher in male than in female patients (P = 0.013). The percentage of solid tumor was higher in males than in females (P = 0.036). Capsule, bleeding, and enhancement in the arterial and venous phases were not significantly different between the male and female patients (all P > 0.05). The imaging features of male SPNP are distinct from those of female patients. In males with pancreatic lesions, MSCT generally shows relatively small lesions with higher percentages of solid components and calcification, with typical enhancement suggesting SPNP.

男性和女性胰腺实性假乳头状肿瘤的临床表现和多层计算机断层扫描特征

胰腺实性假性乳头状肿瘤(SPNP)在男性中很少见,常常被误诊。本研究旨在分析SPNP患者的临床和多层计算机体层摄影(MSCT)特征,并检查男性和女性之间的差异。在这项回顾性队列研究中,我们收集了2010年8月至2018年12月在连云港市第一人民医院接受根治性切除术并经术前MSCT的29例经组织病理学证实为SPNP的患者的临床和影像学数据(男7例,女22例)。所有的MSCT图像均由两名放射科医生检查过;分歧由第三者裁定。29名SPNP患者的中位年龄为30岁(12-70岁)。男性患者年龄大于女性患者[中位数,分别为56(28-66)vs. 29(12-70),P = 0.012]。男性SPNP患者的中位肿瘤大小为3.9(范围2.0–6.4)cm,显着低于女性患者的7.0(范围4.6–14.6)cm(P <0.001)。男性的SPNP钙化率明显高于女性(P = 0.013)。男性实体瘤的百分比高于女性(P = 0.036)。男性和女性患者之间的胶囊,出血和动脉期和静脉期的增强无显着差异(所有P> 0.05)。男性SPNP的影像学特征与女性患者截然不同。在患有胰腺病变的男性中,MSCT通常显示相对较小的病变,其固形成分和钙化的百分比更高,典型的增强提示SPNP。显着低于女性患者的7.0 cm(4.6-14.6)cm(P <0.001)。男性患者的SPNP钙化率明显高于女性患者(P = 0.013)。男性实体瘤的百分比高于女性(P = 0.036)。男性和女性患者之间的胶囊,出血和动脉期和静脉期的增强无显着差异(所有P> 0.05)。男性SPNP的影像学特征与女性患者截然不同。在患有胰腺病变的男性中,MSCT通常显示相对较小的病变,其固形物和钙化的百分比更高,典型的增强提示SPNP。显着低于女性患者的7.0 cm(4.6-14.6)cm(P <0.001)。男性患者的SPNP钙化率明显高于女性患者(P = 0.013)。男性实体瘤的百分比高于女性(P = 0.036)。男性和女性患者之间的胶囊,出血和动脉期和静脉期的增强无显着差异(所有P> 0.05)。男性SPNP的影像学特征与女性患者不同。在患有胰腺病变的男性中,MSCT通常显示相对较小的病变,其固形成分和钙化的百分比更高,典型的增强提示SPNP。男性患者的SPNP钙化率明显高于女性患者(P = 0.013)。男性实体瘤的百分比高于女性(P = 0.036)。男性和女性患者之间的胶囊,出血和动脉期和静脉期的增强无显着差异(所有P> 0.05)。男性SPNP的影像学特征与女性患者截然不同。在患有胰腺病变的男性中,MSCT通常显示相对较小的病变,其固形物和钙化的百分比更高,典型的增强提示SPNP。男性患者的SPNP钙化率明显高于女性患者(P = 0.013)。男性实体瘤的百分比高于女性(P = 0.036)。男性和女性患者之间的胶囊,出血和动脉期和静脉期的增强无显着差异(所有P> 0.05)。男性SPNP的影像学特征与女性患者截然不同。在患有胰腺病变的男性中,MSCT通常显示相对较小的病变,其固形成分和钙化的百分比更高,典型的增强提示SPNP。男性和女性患者的动脉和静脉相的增强和增强没有显着差异(所有P> 0.05)。男性SPNP的影像学特征与女性患者截然不同。在患有胰腺病变的男性中,MSCT通常显示相对较小的病变,其固形成分和钙化的百分比更高,典型的增强提示SPNP。男性和女性患者的动脉和静脉相的增强和增强没有显着差异(所有P> 0.05)。男性SPNP的影像学特征与女性患者截然不同。在患有胰腺病变的男性中,MSCT通常显示相对较小的病变,其固形成分和钙化的百分比更高,典型的增强提示SPNP。
