What are cyst and tumor on ultrasound?

What are cyst and tumor on ultrasound?

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. ...Read more

Sonogram (Definition)

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

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?

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. ...Read more

Difference between dermoid cyst and malignant tumor on ultrasound?

Difference between dermoid cyst and malignant tumor on ultrasound?

No dx on US: • A dermoid cyst is a teratoma presenting as a cystic structire containing an array of developmentally mature tissues. It is usually benign, growing slowly. In rare instances squamous Ca found in the adult patient. While frequent in ovary other sites can be involved. Removal when inflammed, painful or growing. US can suggest complex cyst but Ca dx by path exam and PET scan. ...Read more

Ultrasounds effective at detecting tumors? Are ultrasounds effective at detecting tumors? Should I be worried about cancer in my abdomen even if I have clean bloodwork and an ultrasound that showed nothing?

Very good: Ultrasound can detect tumors or masses between 2 - 3 mm, but it depends on the site and the surrounding tissues. Thyroid, pancreas, ovary, liver, etc are all organs that can be screened with ultrasound. But, you have to make sure it is a technically well performed study without any limitations. ...Read more

What is the smallest tumor ultrasound can detect?

What is the smallest tumor ultrasound can detect?

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. ...Read more

Doctors, what is the difference between a cyst and tumor on an ultrasound?

Doctors, what is the difference between a cyst and tumor on an ultrasound?

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. ...Read more

Which is better for detecting ovarian tumors ultrasound or cat scan, my pelvic ultrasound said solid mass, CT said no mass?

Which is better for detecting ovarian tumors ultrasound or cat scan, my pelvic ultrasound said solid mass, CT said no mass?

Complimentary: Ct ; ultasound are complimentary imaging modalities. For smaller masses in appropriate location ultrasound may have an advantage especially if done transvaginally. For larger masses ct may have the advantage of not being blocked by bowel gas and being less degraded by large body habitus. More specific info in your case would be helpful. Size of mass? How was the sono done? Ct with oral and IV cont. ...Read more

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?

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. ...Read more

Is it possible to detect a tumor via a Doppler ultrasound in the leg?

Is it possible to detect a tumor via a Doppler ultrasound in the leg?

Yes: Most of the lesions in the leg are primary sarcomas. There are very few metastatic lesions other than those spreading to groin nodes. Sarcomas grow as masses and can easily be palpated. If the lesion is deep to skin and begins growing, it spreads the overlying tissue over it so that the margins of the growing lesion may not be clear. Here a Doppler should easily identity its true margins. ...Read more

Breast tumor shows up on ultrasound. Can it be bad if no one had felt it?

Breast tumor shows up on ultrasound. Can it be bad if no one had felt it?

Need bx to be sure: Ultrasound characteristics can suggest benign versus malignant in appearance but the most definitive diagnosis is always made by a pathology evaluation of a tissue sample (core needle biopsy).
Ultrasound is an extension of the physical examination allowing one to get additional information about an area palpated or seen on other imaging (i.e. Mmgs, bmri) that may be too small or deep to be felt. ...Read more

I had a papsmeare and the doctor said he can feel either a cyst it a tumor. I'm getting an ultrasound friday. How is that performed?

Ultrasound how-to: The technician or your doctor will take some gel and place it on your skin over the area to imaged. The ultrasound head puts out noiseless waves of sound which echo back. The differences in time and quality of the echoes produce an image. Doesn't hurt, just leaves you sticky afterwards! ...Read more

Ubknown: I would need much more information. A breast "adenoma" is probably meant to be a benign (non-cancerous) fibroadenoma ; would not be related to a pituitary adenoma. The biopsy will give you the information you need. ...Read more

Can an ultrasound tell if spot in kidney is a tumor?

Can an ultrasound tell if spot in kidney is a tumor?

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. ...Read more

What's the probability of a trans vaginal ultrasound missing a tumor on your ovary?

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. ...Read more

I am getting a pelvic ultrasound tomorrow. Will they tell me if I have a tumor or cyst?

Maybe: A pelvic ultrasound can be very helpful to distinguish between a cyst (hollow) or a tumor (solid). Sometimes the findings are equivocal (may look mixed solid-hollow) and further studies have to be done but it's pretty good at telling which is which and very little discomfort involved. ...Read more
