A retrospective analysis of 84 ultrasound examinations (in 77 patients) was performed to assess the frequency of sonographic findings in chronic pancreatitis. The findings included: inhomogeneously increased echogenicity in 53% of these examinations, focal or diffuse enlargement in 41%, focal dense echoes in 40%, pseudocyst formation in 21%, and a hypoechoic head mass in 7%. Thirteen per cent of our patients had a normal sonogram. Several presentations of chronic pancreatitis not previously described in the sonographic literature included: pancreatic or common bile duct enlargement or pseudocyst formation with otherwise normal-appearing glands. There was no direct relationship between the presence of focal high-intensity echoes within the pancreatic parenchyma and the presence of radiographic calcification. There was no difference in the frequency of ultrasonic abnormalities between patients with and without clinical evidence of pancreatic insufficiency. These results indicate that the sonographic findings in chronic pancreatitis are significantly more varied than previous reports would indicate.
对77例患者的84次超声检查进行回顾性分析，以评估慢性胰腺炎超声检查结果的频率。结果包括：53%的检查中回声不均匀增强，41%有局灶性或弥漫性肿大，40%有局灶性密集回声，21%有假囊肿形成，7%有低回声头部肿块。13%的患者超声检查正常。慢性胰腺炎的几种表现此前在超声文献中未被描述，包括：胰腺或胆总管肿大或假囊肿形成，而腺体外观正常。胰腺实质内局灶性高回声的存在与放射学钙化的存在之间没有直接关系。有和没有胰腺功能不全临床证据的患者之间超声异常的频率没有差异。这些结果表明，慢性胰腺炎的超声检查结果比以前的报告所显示的要丰富得多。
