A 60-year-old woman undergoes screening mammography. A cluster of microcalcifications is described as 'amorphous and indistinct' on magnification views. They are scattered in distribution. According to BI-RADS, amorphous microcalcifications are classified under which category of suspicious morphology?
- A Intermediate suspicion ✓
- B Typically benign
- C High suspicion
- D Benign
Correct answer: A. Intermediate suspicion
Explanation
Amorphous microcalcifications are small and hazy, with indistinct margins, making it difficult to determine their shape. They fall into the intermediate suspicion category in BI-RADS. Fine pleomorphic calcifications are also intermediate suspicion. Fine linear or fine linear branching calcifications are in the high suspicion category. Typically benign calcifications include skin, vascular, coarse popcorn-like, and eggshell types.
