Answer

Simple cysts have 4 criteria:

  • They are usually well defined and round or ovoid.

  • They have thin smooth walls.

  • They contain no internal echoes.

  • They have posterior acoustic enhancement (see the image below).

Diagnosing a simple cyst means that the lesion is benign and that no further testing is needed. However, if a lesion does not meet all 4 criteria for a simple cyst, it is classified as either a complex lesion or a solid lesion.
