Simple cysts are very common in the middle-aged and elderly. They are filled with clear fluid with ‘acoustic enhancement’.

Most cysts are spherical in shape. They may be solitary or multiple, unilocular or have septations.

*When the ultrasonographer is sure that the diagnosis is a simple cyst, no further investigation is needed. *

Indeterminate lesions with both cystic and solid components need further evaluation with CT..
