Transabdominal ultrasound has low sensitivity varying between 0 to 66% in detecting insulinoma. The sensitivity increases with the use of more invasive technique including endoscopic ultrasound (93%) and intra-operative ultrasound (86%). Hypo-echoic lesions and hypervascular mass are seen on the ultrasound.
