Answer

Answer

A complex cyst is a lesion that lacks one or more of the 4 criteria for a simple cyst. Complex cysts may contain internal echoes, limited posterior acoustic enhancement, wall irregularity, and/or an irregular shape. Further evaluation with cyst aspiration usually is recommended to exclude malignancy.
