A breast cyst with internal echoes and evident vascularity would be classified as which type?

• A. Simple cyst
• B. Complicated cyst
• C. Complex breast cyst
• D. Hemorrhagic cyst

Answer: (C)

Understanding how ultrasound labels breast cysts hinges on what’s inside the cyst and whether there’s any blood flow within it. A simple cyst is purely fluid-like: it’s anechoic, with posterior enhancement, a thin smooth wall, and no internal echoes or Doppler flow. If you see echoes inside the cyst, that means material other than fluid is present (debris, protein, or blood products). If Doppler shows flow within the cyst, that indicates vascularized tissue inside rather than just fluid, pointing to a solid component. So a cyst that has internal echoes and readable vascularity is best described as a complex breast cyst. The other categories don’t fit as well: a simple cyst lacks internal echoes and flow; a complicated cyst may have debris but typically lacks internal vascularity; a hemorrhagic cyst involves blood products and may still lack significant internal flow.
