komplizierte Zyste Mamma
Complicated breast cysts are one of the cystic breast lesions that show intracystic debris which may imitate a solid mass appearance. They should be carefully differentiated from a complex cyst and may require alternative management .
Radiographic features
Ultrasound
- thin wall with or without posterior acoustic enhancement
- homogenous hypoechoic content
- low-level internal echoes which may change the shape with the patient position
- sloping fluid-fluid levels
The challenge is to differentiate a complicated from a complex cyst as the low internal echoes of a complicated cyst may appear as a homogeneous hypoechoic mass .
If there is hemorrhagic or inflammatory debris which is adherent to the wall, applying power Doppler and detection of internal vascularity can positively prove it to be a solid mass lesion. On the other hand, Doppler cannot exclude it .
Treatment and prognosis
Complicated breast cysts have less than 2% risk of malignancy and are recommended to be reported as probably benign . Thus, the management is limited to :
- short interval follow up
- if the size changes over 6 months by >20%, a diagnostic biopsy is indicated
- aspiration
- indicated in a symptomatic patient to relieve the symptoms, newly detected cyst, and enlarged cysts
In all cases, if aspiration reveals serosanguineous fluid, then cytological analysis should be performed.
