Contains updates to 2013 version
Algorithms for incidental cysts detected on ultrasound originate from 2019 Society of Radiologists in Ultrasound (SRU) consensus update for follow-up and reporting for simple adnexal cysts
Definitions
Simple cyst: Sonographically characterized
Round/oval lesion
Smooth, thin walls
No solid component or septation
No internal blood flow
Simple-appearing cyst: CT/MR terminology
Round/oval lesion
Fluid attenuation (-10 to 20 HU)
MR fluid signal (T2 hyperintense, T1 hypointense)
Smooth, imperceptible or thin wall
No enhancement
