title: A case of serous cystadenoma of the pancreas with a central stellate scar detected on contrast-enhanced ultrasound with perflubutane.
abstract: An asymptomatic 66-year-old woman was admitted to our hospital for detailed evaluation of a 63-mm mass in the tail of the pancreas detected on abdominal computed tomography (CT). Abdominal ultrasound (US) revealed a hypoechoic solid mass, but on contrast-enhanced ultrasound (CE-US) with perflubutane, a stellate structure within the tumor, characteristic of a serous cystadenoma, was observed. A distal pancreatectomy was performed, and histologic examination confirmed a serous cystadenoma of the pancreas. This case highlights the usefulness of CE-US with perflubutane for diagnosis of pancreatic serous cystadenomas.
