“…Although a small IDC is usually depicted as a solid, low-echoic mass on EUS [5] , the initial EUS in this case showed an extremely low-echoic mass resembling a cyst with an unclear margin. Histopathologically, the IDC included macroscopic retention cysts.…”

This report describes serial observations of the growth process of a small invasive ductal carcinoma (IDC) of the pancreas from imaging studies. Histopathological studies showed IDC with macroscopic retention cysts proximal to an intraductal papillary-mucinous adenoma with mild atypia of the branch duct type in the pancreatic body, with no relation between the two lesions. IDC was demonstrated as an extremely low-echoic mass resembling a cyst with an unclear margin on the initial endoscopic ultrasonography. We misinterpreted the lowechoic mass as a benign intraductal mucinous-papillary neoplasm (IPMN) based on findings of other imaging studies, and the patient was followed-up. The mass increased from 7 mm to 13 mm in diameter over 22 mo, and remained smaller than 10 mm in diameter for about 420 d. The tumor volume doubling time was 252 d. The Ki67 labeling index was 15.9%, similar to that described in previous reports. Hence, IDC may grow slowly while remaining small.

“…Although other modalities such as MRI and MRCP may be more useful in differentiating IPMN or MCN from SCN, differentiating the macrocystic type of SCN from other cystic tumors is still difficult. EUS has been proposed as an ideal imaging technique for pancreatic cystic lesions [29,30,31]. Ultrasound can readily characterize cysts, and high-resolution imaging of the pancreas can be achieved through endoscopic means.…”

“…EUS is the most sensitive method for diagnosing EPTs and a mean 90% (range 77–100%) detection rate was shown in 10 studies comprising 261 patients [10,29,30,31,33,34,35,36,37,38]. In a study on 75 patients the sensitivity was 93% and the specificity 95% [39].…”
