Core Tip
Core Tip: Most solid pseudopapillary neoplasms of the pancreas (SPN) are indolent tumors that could yield a perfect prognosis with complete surgical resection. Approximately 8% of pancreatic ductal adenocarcinoma (PDAC) may have cystic characteristics, which share similar radiological imaging features with SPN and lead to misinterpretation. It would be of great clinical value to preoperatively differentiate SPN from PDAC with cystic changes. In this study, a larger tumor size, “floating cloud sign,” and peripancreatic invasion or distal metastasis are useful computed tomography imaging features that are more common in SPN and may help discriminate SPN from PDAC with cystic changes.
