Abstract

A 42-year-old woman was found to have a pancreatic tumor by transabdominal ultrasonography (US) on a health check-up in our hospital. US identified the 18 mm hypoechoic mass with an unclear irregular boundary and a heterogenous content in the pancreatic body. Contrast-enhanced computed tomography visualized the hypovascular lesion. Contrast-enhanced US showed blood flow inside the mass, but it was hypovascular compared with the surrounding pancreatic parenchyma. Based on the diagnosis of solid-pseudopapillary neoplasm of pancreas (SPN), we conducted distal pancreatectomy with splenectomy. We diagnosed it as SPN of pancreas histologically. US and CE-US is useful in the preoperative diagnosis for SPN.
