Abstract:
The lactating adenoma is a benign breast lesion occurring as a palpable mass in pregnant or lactating patients. The ultrasound characteristics of 15 lactating adenomas in 15 patients were reviewed retrospectively. Most of the lactating adenomas in this series (10 of 15) had one or more typically benign features such as circumscribed borders, smooth lobulations, or an echogenic pseudocapsule. The remaining five, however, had features typically associated with malignancy, including irregular, angulated, or ill-defined margins, or posterior acoustic shadowing.

Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...
01:20Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
