BREAST CYST FORMATIONS CLASSIFICATION Russian patent published in 2017 - IPC A61B8/06 A61B8/08 

FIELD: medicine.

SUBSTANCE: ultrasound examination of the breast is performed. If an anechoic formation is found in a thin capsule with an increase in the dorsal shadow, the cystic formation is classified as a simple cyst, type C1. When multiple anehogenous formations are found, the cystic formation is classified as cluster mini-cysts, type C2. When anechoic formations with thin intracavitary septa are found, without increasing blood flow in the Doppler colour mapping mode, the cystic formation is classified as cysts with thin septa, type C3. When formations with clear contours and thick contents are found, without increasing blood flow in the DCM mode, the cystic formation is classified as complex cysts with thick uniform content, type C4. When anechoic formations with thickened, uneven capsule or a septum or intra-cavity growths with increased blood flow are found in the DCM mode, the cystic formation is classified as cysts with thick capsule or thick rough intra-cyst septa and intra-cyst growths, type C5. When anechoic formations with asymmetric liquid inclusions are found, with increased blood flow in the DCM mode, the cystic formation is classified as cysts with mixed tissue and fluid contents, type C6. If there is an expansion of ducts exceeding 0.4 cm, without duct walls visualization, the cystic formation is classified as duct ectasia, type D1. If an anechoic formation is found in a thin capsule with a duct connection, the cystic formation is classified as pseudocysts or cystic duct dilations, type D2. When a thickening of the duct wall or intraduct growths are detected, the cystic formation is classified as intraduct growths with tone decrease in the duct, type D3.

EFFECT: method provides increased accuracy of differential diagnosis of cystic breast formations.
