Biopsy was recommended for complex cysts, if not corresponding to benign lesions like oil cyst. The status of axilla was evaluated for inflammatory lesions such as abscess or mastitis in terms of lymphade-nopathy.
However, for complex cysts mammography was performed, particularly to differentiate oil cysts from suspicious lesions.
The risk of buttock augmentation are as follows: blood clots, hematoma, swelling and bruising, excessive blood loss, complications of anesthesia or liposuction, oil cyst
, fat embolism and revision of surgery at a later date, according to the (https://www.plasticsurgery.org/cosmetic-procedures/buttock-augmentation/safety) American Society of Plastic Surgeons .
In patients with complex cystic masses, mammography may help to characterize the mass and depict associated micro calcifications and show suspicious lesions If a lesion appears fat-containing at mammography, it represents a benign entity such as an oil cyst
or galactocele, and biopsy can be avoided.
Similarly, an anechoic mass with shadowing that corresponds to a mammographically benign lesion, such as an oil cyst
, should be followed.

appear as either simple or complicated cysts.
The predominant imaging changes were fat necrosis and oil cysts
