Pancreatic serous cystadenoma seen on contrast-enhanced ultrasound

Pancreatic serous cystadenomas are characterized by microcysts that are smaller than 20 mm. The typical vascular architecture is characterized by a centrally located arterial blood supply (A - Doppler imaging). The lesion is hyperenhancing on contrast-enhanced ultrasound (B - transcutaneous ultrasound; C - endoscopic ultrasound).
