Tumors 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
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
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 moreSee 1 more doctor answer
On CT the doctors found multiple exophytic solid masses on bilateral kidneys. What is the likely diagnosis, cancer?
Could be: Different things- including benign tumors ( like lipoma, stromal tumor, adenoma, fibroma etc)- , however malignancy is something that is absolutely has to be ruled out. You need a biopsy of the kidney mass definitively. Discuss further with your doctor. ...Read moreSee 1 more doctor answer
maybe: A large pituitary tumor, or macroadenoma, may be large enough to be visible on ct, but a small pituuitary tumor, or microadenoma, will probably not be visible. An MRI (without and with contrast) of the pituitary is the preferred method to evaluate this structure. ...Read moreSee 1 more doctor answer
Yes and no: Causality is hard to prove in medicine. Multiple ct exposure - especially in the young has been associated with increase risk of certain cancer but not all kids who had cts will have cancer. Thyroid scan and ultrasound have not been specifically implicated as contributors to the process of cancer development. ...Read moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
Many things: The general categories are Infection, Cancer, Non-cancer tumors, collapsed lung, blood, fluid, and more. The radiologist should be able to narrow down the potential causes from the appearance. Ask for a detailed radiology report. If this doesn't satisfy you, speak with your primary care doctor. ...Read more
Yes: If a testicular cancer is very small, doesn't look different from the remainder of the testicle, or is "burned out" it may not be seen. "burned out" means the tumor has shrunken in the testicle (often leaving nothing but a scar or calcification) and the tumor is only found by patient metastases, often enlarged lymph nodes. Lastly, an inexperienced sonographer can just not see it. ...Read more
Different imaging.: Sometimes things can be well demonstrated on ct and not ultrasound and vice versa. I'd need your studies to compare. Occaisionally, there are artifacts with either modality that can mimic a mass when there really isn't one. Bowel loops can often do this with either test. ...Read more
Ct scan found mass on pancreas, adnocarcinoma in acities. Pet scan found no masses. Doctors said they are confused. What could this be?
Normal variation: The position of the ovaries varies quite a bit from women to women within the pelvis. Secondly, gas within adjacent bowel loops will distort ultrasound images and 'hide' anything behind that loop. Thus looking from a different angle ie transvaginally, we can find the ovaries that we can see on the transabdominal portion of a scan. ...Read more
What's the minimum size of liver and/or kidney lesions (in mm) that can be detected on CT scan and ultrasound?
About 10mm: About 10mm, but at that size it can depend a lot on how good the study was done. (if the operators were able to get ideal positioning for image capture), the anatomy of the patient (it's harder to get enough resolution on obese patients), and it can depend on what the lesion is - if it is solid, a simple vs complex fluid, calcified, etc. Hope this helps ...Read more
In er, ultrasound showed cysts on both ovaries, and one cyst was lumpy. Could this be ovarian cancer?
It might be.: A cyst might be simple or multi-loculated, that is, many cysts in one with many walls that could contain cancer cells. The cyst might be filled with blood, a hemorrhagic cyst, or fluid, or be something else entirely. That's why it should be examined and possibly removed by laparoscopy, etc.. It would be wise to see your doctor for an exam. Good luck. ...Read more
