🩺 Multiple Breast Nodules on Ultrasound: Should You Worry?

Many patients become anxious when they hear
“multiple nodules” on breast ultrasound.

However, not all nodules are dangerous.

This case represents:

👉 Fibrocystic change (FCC)
👉 Especially clustered microcysts

🔍 Why do they look like a mass?

Ultrasound shows only a slice at a time.

👉 Multiple small cysts may appear as
a single solid-looking lesion (pseudo-solid appearance)

📊 Key Features of Clustered Cysts

• Multiple small cysts grouped together
• Smooth margins
• Hypoechoic or anechoic
• Posterior acoustic enhancement
• No internal vascularity

👉 These features strongly suggest benignity

❗ How to differentiate from cancer?

Feature	Clustered cyst	Malignancy
Shape	Round/oval	Irregular
Margin	Smooth	Spiculated
Orientation	Parallel	Taller-than-wide
Posterior	Enhancement	Shadowing
Vascularity	None	Often present

📌 Final Impression

👉 Fibrocystic change with clustered cysts
👉 BI-RADS 2 (benign)

“Clustered cysts can mimic a solid mass on ultrasound. Always evaluate in multiple planes.”
