Solid appearance of pancreatic serous cystadenoma diagnosed as cystic at ultrasound acoustic radiation force impulse imaging

CONTEXT: Acoustic radiation force impulse imaging is an emerging imaging modality. The study of the pancreas is a new and promising application of ultrasound acoustic radiation force impulse imaging. CASE REPORT: We present the first case of pancreatic serous cystadenoma which mimics a solid neoplasm at conventional imaging (US and CT), correctly diagnosed as cystic at ultrasound acoustic radiation force impulse imaging. CONCLUSION: The "XXXX" values always measured at Virtual Touch tissue quantification allow the diagnosis of a pancreatic cystic lesion with simple fluid content suggesting the diagnosis of serous cystadenoma.
