What Do Tumors Look Like On An Ultrasound
An ultraound, also known as a sonogram, is a painless and relatively inexpensive imaging test that utilizes sound waves instead of ionizing radiation. There are no side effects. Ultrasound can give us two-dimensional, and in some applications three-dimensional, images of structures and organs in virtually any part of the body. In addition to diagnostic uses, such as evaluating abnormalities in the abdomen, pelvis, and breast, ultrasounds are commonly used to guide needle and catheter placement in a variety of surgical ...Read more
Can a maligant tumor in postauricular lymph node look like a complex sebaceous cyst in ultrasound?
Posssibly: A mass in that area can be solid or echogenic and could be malignant or benign but the ultrasound will not be definitive in some cases.See 1 more doctor answer
Breast Imaging: Occurs after finding a lump, or on a screening mammogram. The u/s can show if the lump is cystic or solid, with color, vascularity, and estimate charcteristic of benign or malignant. Current u/s is hand held, done by a tech, and reviewed by a radiologist. It can provide size and shape information, and see if there are other lesions.
It looks: Like a solid mass different from the surrounding breast tissue. It may be smooth or irregular in contour and may or may not have associated blood flow changes in it. Sometimes calcifications are identified.
No clear number: There is no specific size that is required for an ultrasound to be accurate. An ultrasound looks both at the size and shape of a nodule, but also looks at what kind of shadow is cast by the nodule when the ultrasound directs the waves toward the area. Ultrasound can be very helpful to assess lymph nodes as small as 1 cm for women with breast cancer.
Good question: A simple cyst is a collection of fluid with no associated abnormal soft tissue growth around or inside it. A tumor, or abnormal growth of tissue, may have cysts associated with it depending on what kind of tumor it is. That is why we have to be very careful when we look at cysts so that we know when something is a simple cyst and when it might be a tumor with cysts in it. I'm generalizing here.
It helps to image tu: Ultrasound is a good test to screen for tumors and cysts in the internal organs. It is one of the several imaging technologies which can be a good screen to start with.
How small of a tumor can ultrasound find? I know the technology is getting better all the time, but what's the smallest size tumor modern ultrasound equipment can detect?
Depends on organ: Ultrasound of the thyroid can find 3 mm nodules; but, this level of sensitivity is not quite a good in the liver or breast. It depends on the organ being evaluated. Ovary, liver, pancreas, prostate, thyroid, lung and even esophagus can all be test by ultrasound.See 1 more doctor answer
Yes: If over 5 - 10 mm, it would show up.See 1 more doctor answer
Solid or cystic: Ultrasound can tell if a lesion in the kidney is solid or cystic. A simple, uncomplicated cyst is usually nothing to worry about, and therefore no further workup would be needed. However, an ultrasound cannot tell if a solid mass is benign or malignant, so if the lesion is solid, further evaluation would be necessary.See 1 more doctor answer
Maybe: "fat ball" is the familiar angiomyolipoma. A lipid-laden renal cell carcinoma may mimic it. Ask your physician about the radiologist's level of confidence and whether to obtain tissue for study.
Yes: Ultrasound is a very good way to look at the testicle, and would be able to see quite small changes.
Ultrasound: A simple cyst is generally a rounded, thin walled structure filled with uncomplicated fluid. It will look like a black circle on US. A neoplasm may be cystic, but may have a thicker or irregular wall, internal solid components or septations, along with fluid. It may be completely solid too. Infrequently there is some overlap of features and it may be difficult to tell the difference.
Yes: Ultrasound is a great tool for finding tumors. It is noninvasive, painless, and can be easily repeated. It is excellent for assessing the thyroid gland, lymph node areas, the liver, and the breast, among other areas.See 1 more doctor answer
What is the probability that a lipoma would be labeled as that in ultrasound when really it's a tumor that needs to be biopsied?
Not common: Patients that are overweight may limit the visibility of the ovaries, but in the majority of patients, the ovaries can be identified with transvaginal ultrasound. The ovaries, after menopause, may become too small to identify with certainty. Unfortunately, there is still no satisfactory method for screening for ovarian cancer prior to a patient becoming symptomatic.
Abnormal area found in placenta on ultrasound. Dr said maybe clot or tumor. Would an abruption be noticeable also if it was a clot?

Is it true that if a structure is hypoechoic, it consists mostly of air or fluid? So why are pancreatic tumors usually hypoechoic in ultrasounds?
It is not true.: Air completely reflects the US beam so it has no internal echogenicity. Depending on other characteristics, a hypoechoic structure could be a solid mass or fluid filled. Most solid tumors are hypoechoic relative to adjacent tissue.See 1 more doctor answer
