If an finds a hypoechoic mass, you may have wondered what that means.A hypoechoic mass looks dark gray on an ultrasound. That means the tissue is dense. It doesn’t always mean that something is wrong.How Ultrasound WorksUltrasound works by sending sound waves toward the object being tested. A machine records the sound waves. These are also called echoes. They bounce back and create an image that can be seen on a screen. The image is sometimes called a .Diagnostic ultrasound uses sound wave technology to look at parts of your body, including:Heart and blood vesselsBreastAbdominal OrgansEyesSkin and musclesTypes of Ultrasound ImagesCertain words are used to describe areas imaged with ultrasound. Masses can be hypoechoic, hyperechoic, anechoic, or mixed.Hypoechoic. This term means "not many echoes." These areas appear dark gray because they don't send back a lot of sound waves. Solid masses of dense tissue are hypoechoic. Hyperechoic. This term means "lots of echoes." These areas bounce back many sound waves. They appear as light gray on the ultrasound. Hyperechoic masses are not as dense as hypoechoic ones are. They may contain air, fat, or fluid.Anechoic. This term means "without echoes." These areas appear black on ultrasound because they do not send back any sound waves. Anechoic masses are often fluid-filled.Are Hypoechoic Masses Cancerous?Ultrasounds are one tool in determining whether a mass is cancerous. Solid masses are hypoechoic and can be cancerous. filled with air or fluid are usually hyperechoic and are rarely cancerous. Abnormal tissue also looks different from healthy tissue on a sonogram. Your doctor will usually do further testing if an ultrasound shows a solid mass or what looks like abnormal tissue.Ultrasounds help doctors identify benign or malignant tumors. are usually all one type of tissue. They typically have clearly defined borders. They don't invade other organs. But they may push on them or displace them.Cancerous masses may contain more than one type of tissue. They often have irregular borders. They may invade nearby organs. It isn’t easy to tell the difference between benign and malignant masses. There can be an overlap between both types. Other ConditionsUltrasound results can mean different things depending upon which part of the body is being tested. Here are a few examples of hypoechoic masses that can happen in different areas.Breast. Hypoechoic masses with irregular shapes in are suspicious. Some benign masses can be hypoechoic and may look like . Ultrasound operators use special techniques to tell the difference between benign and . Sometimes are necessary.Thyroid. Many people have (lumps). But only about 5% of . Ultrasound helps doctors find the ones that might be. Hypoechoic nodules that are 2 centimeters or more and contain calcium deposits are most likely to be cancerous.Uterus. of the uterus are often found during ultrasound exams. They are benign but may be hypoechoic on a sonogram. Many women with fibroids have no symptoms. Fibroids are not cancerous, but they can cause severe symptoms.SourcesUpdate HistorySharePrintSOURCES:ACTA INFORMATICA MEDICA: "Application of Ultrasound in Medicine."Cancer Treatment Centers of America: "Ultrasound."CLINICAL THYROIDOLOGY FOR THE PUBLIC: "THYROID NODULES."INDIAN JOURNAL OF RADIOLOGY AND IMAGING: "Radiological appearances of uterine fibroids."Korean Journal of Radiology: "Are Irregular Hypoechoic Breast Masses on Ultrasound Always Malignancies?: A Pictorial Essay."National Institute of Biomedical Imaging and Bioengineering: "Ultrasound."RadiologyInfo.org: "General Ultrasound."Silkowski, C.

Breast calcifications are calcium deposits that commonly develop in breast tissue. They’re painless and too tiny to feel with your fingers, so you likely won’t know you have them unless they appear on a mammogram. A mammogram is a low-dose X-ray that detects atypical growths in breast tissue., Calcifications, or small groupings of calcium found in breast X-rays, are one of the most common findings in breast imaging. Calcifications have different characteristics that indicate whether they are benign or need follow-up or further testing., On mammography, foreign body reactions can be seen as calcifications or microcalcifications but can also be seen as a mass that simulates malignancy because of its ill-defined or partially circumscribed margin (6, 7). At US, the lesion can show an irregular spiculated hypoechoic mass (Fig. 1)., Coarse heterogeneous calcifications have a 15% positive predictive value (PPV) of malignancy. Beyond morphology, the distribution of calcifications is an important predictor of malignancy., The most typical sonographic presentation of a malignant breast mass would probably be an irregular, heterogeneous, hypoechoic mass with spiculations and angular margins., Additional calcifications in the left breast at 8 o'clock at anterior depth located 2 centimeters from the nipple, three additional groups of calcifications in the central and lower inner left breast are also suspicious (small white circles)..
