Usefulness and Limitations of Breast Ultrasound in Palpable Breast Masses

In Patients with palpable breast masses:

Ultrasound

  • Sensitivity – 92.5%
  • Cystic mass – 100%
  • Carcinoma – 57.1%
  • Fibroadenoma – 75%

ROJoson’s Notes (16may13):

Ultrasound may not be able to detect all palpable breast masses.

It is good in differentiating between cystic and solid nodules.

The 100% is just for this series of patients. In reality, there is no such thing as 100%, at most, 99%.
