新一代多层螺旋CT技术有助于识别胰腺中的小而无强化的病变。这项研究的目的是确定在16-MDCT上意外发现的胰腺囊肿在成人门诊患者中的流行率，这些患者被成像为与胰腺无关的疾病。我们回顾了2832次连续检查中增强的腹部多层螺旋CT扫描，以确定胰腺囊肿。有胰腺病变史或胰腺疾病易感因素的患者或接受胰腺CT检查的患者被排除在外。共有73名患者有胰腺囊肿，患病率为2.6/100(95%可信区间，2.0-3.2)。囊肿大小为2~38 mm，平均8.9 mm，85%为单发。人口学资料分析显示，胰腺囊肿率与年龄密切相关，40岁以下的患者中未发现囊性病变，80岁至年龄段的患病率为8.7‰(95%可信区间，4.6~12.9)。在控制了年龄后，囊肿病在亚洲种族中比所有其他种族类别中更常见，优势比为3.57(95%可信区间，1.05-12.13)。囊肿率在性别上没有差异(p=0.527)；然而，男性的囊肿率平均比女性大3.6 mm(p=0.014)。在这一门诊人群中，16-MDCT发现的意外胰腺囊肿的患病率为2.6%。囊性病变的出现与年龄和亚洲种族的增加密切相关。
Current generation MDCT technology facilitates identification of small, nonenhancing lesions in the pancreas. The objective of this study was to determine the prevalence of findings of unsuspected pancreatic cysts on 16-MDCT in a population of adult out-patients imaged for disease unrelated to the pancreas. Contrast-enhanced MDCT scans of the abdomen were reviewed from 2,832 consecutive examinations to identify pancreatic cysts. Patients with a history of pancreatic lesions or predisposing factors for pancreatic disease or who were referred for pancreatic CT were excluded. A total of 73 patients had pancreatic cysts, representing a prevalence of 2.6 per 100 patients (95% CI, 2.0–3.2). Cysts ranged in size from 2 to 38 mm (mean, 8.9 mm) and were solitary in 85% of cases. Analysis of demographic information showed a strong correlation between pancreatic cysts and age, with no cysts identified among patients under 40 years and a prevalence of 8.7 per 100 (95% CI, 4.6–12.9) in individuals from 80 to 89 years. After controlling for age, cysts were more common in individuals of the Asian race than all other race categories, with an odds ratio of 3.57 (95% CI, 1.05–12.13). There was no difference by sex in the prevalence of cysts (p = 0.527); however, cysts were on average 3.6 mm larger (p = 0.014) in men than women. In this outpatient population, the prevalence of unsuspected pancreatic cysts identified on 16-MDCT was 2.6%. Cyst presence strongly correlated with increasing age and the Asian race.
