Fig 20.3.6a Lexicon: Orientation: Parallel x Not Parallel. Oval circumscribed mass with parallel orientation
Fig 20.3.6b Lexicon: Orientation: Parallel x Not Parallel. Irregular spiculated mass with no parallel orientation
Fig 20.3.7a Lexicon. Margin: Circumscribed lesion. Fibroadenoma
Fig 20.3.7b Lexicon. Margin: Circumscribed lesion. Simple cyst

Fig 20.3.9 Lexicon. Margin: Not circumscribed - angular. Complex (solid and cystic) mass with angular margin
Fig 20.3.10 Lexicon. Margin: Not circumscribed - microlobulated. A pattern that is often difficult to identify
Fig 20.3.11 Lexicon. Margin: Not circumscribed - spiculated. Hypoechoic mass with irregular shape and spiculated margin. US guided core biopsy confirmed malignant result
Fig 20.3.12 Lexicon. Echo pattern - anechoic: Simple cyst with posterior enhancement. A classic BI-RADS 2 finding
Fig 20.3.13 Lexicon. Echo pattern - hypoechoic: Image shows a hypoechoic no parallel (vertical) circumscribed mass
Fig 20.3.14 Lexicon. Echo pattern - hyperechoic: Image shows a hyperechoic mass (arrow) with no suspicious features

Fig 20.3.16a B-Mode US: suspicious lump, no parallel, with microlobulated margins and small calcifications inside
Fig 20.3.16b Suspicious lump. Color Doppler can prove the solid nature of the lesion
Fig 20.3.17a Special cases. Clustered microcysts
Fig 20.3.17b Special cases. Complicated cyst (circumscribed cyst with debris inside that moved with the patient’s movement). When isolated these findings can be classified in category BI-RADS 3. If multiple and bilateral, benign assessment can be chosen (BI-RADS 2)
