What is the difference between neck cysts and neck nodules I have both?

What is the difference between neck cysts and neck nodules I have both?

Cyst vs nodule: A cyst has a hollow cavity/sac with a fluid/liquid, or somewhat solid material a nodule is relatively hard and not hollow. ...Read more

Cyst (Definition)

A cyst is a structure or mass that consists of a cellular lined sac. It is typically filled with fluid but may be filled with solid material. It can be congenital, traumatic, or acquired. They may develop nearly anywhere in the body and usually require complete excision for eradication or they are likely to recur. Fluid filled sacs that are not cellular lined ...Read more

What's the difference between a breast nodule and a breast cyst?

What's the difference between a breast nodule and a breast cyst?

Solid v Fluid-Filled: A "nodule" is a generic term for a breast lump. Common causes include "lumpy-bumpy" breast tissue ("fibrocystic changes"), tumors (benign or malignant), and cysts (fluid-filled;benign). A thorough history and physical examination supplemented by ultrasound+/-mammography+/-biopsy will help sort this out. ...Read more

Breast nodule or a cyst? I just had a breast ultrasound and was first told they saw a nodule, but then later said is probably a cyst and that it may have even exploded. What does this all mean? What is the difference between a nodule and a cyst?

Breast nodule or a cyst? I just had a breast ultrasound and was first told they saw a nodule, but then later said is probably a cyst and that it may have even exploded. What does this all mean? What is the difference between a nodule and a cyst?

Shadows/echos: A nodule looks solid on ultrasound (us) and a cyst is fluid filled. Depending on the machine quality and technician performing the exam, they can be difficult to distinguish. In these cases the radiologist will often come in the room to take a look or perform the exam. A 3-6 month repeat us is usually advised or you can ask for a biopsy. If you are worried, find a breast surgeon to evaluate you. ...Read more

Please tell me, could a 6mm cyst on liver nodule be a carcinoid?

Please tell me, could a 6mm cyst on liver nodule be a carcinoid?

Cysts are not carcin: A cyst is different than a nodule. The size of 6 mm is too small to call it a carcinoid. Carcinoids will produce nodules on the liver which are solid as opposed to cysts which are fluid filled structures. ...Read more

I123: You will probably need to undergo what is called a i123 nuclear scan and uptake of the thyroid. Findings of heterogeneous non cystic nodules require more information on whether they are worrisome (cold) nodules or non-worrisome (hot) nodules. Cold nodules usually require biopsy to make sure they are not a problem. Not all cold nodules will be problem nodules. ...Read more

I have a complex cyst in my ovary measuring 6.5x8.9x4.5 cm with two nodules with the bigger one measuring 1 cm. Should it be removed and how?

I have a complex cyst in my ovary measuring 6.5x8.9x4.5 cm with two nodules with the bigger one measuring 1 cm. Should it be removed and how?

Recommend excision: Complex cysts should be surgically removed in the large majority of cases as the concern is whether the cyst is benign or malignant. The large majority are benign but there aren't any good tests to make that determination without actually removing the cyst. You should consult a gynecologist and he or she may refer you to a GYN oncologist to do the surgery. A laparoscopy may be appropriate. ...Read more

Mammo with additional testing showed nodule cyst are they the same and can nodule and cyst go away on its own how serious are nodule was told beign?

Mammo with additional testing showed nodule cyst are they the same and can nodule and cyst go away on its own how serious are nodule was told beign?

Complicated question: You're best off using HealthTap Prime or discussing your concerns with your primary care doctor. Nodules (solid) & cysts (fluid filled) are NOT the same thing, but most Radiologists can't tell the difference in the breast since they can be small. Breast tissues can change during the menstrual cycle; but age is a factor here, as well as family history. Can't tell you here if benign or not. TTYD. ...Read more

I have a paraovarian cyst that has a mural echcogenic nodule, is this serious? It's about 2cm and the nodule is 7mm.

I have a paraovarian cyst that has a mural echcogenic nodule, is this serious? It's about 2cm and the nodule is 7mm.

Keep an eye on it: The possibility (differential diagnosis) and clinical implications for ovarian cysts change with a woman's age. For someone young the nodule is more likely benign (like part of a dermoid cyst) than when someone is older where such a nodule can make it more worrisome for cancer, though nothing is 100%.
Also, the size of the cyst (if >4-5cm) can be associated with torsion (surgical emergency) ...Read more

Are isoechoic and hypoecoic nodules and cysts cancerous?

Are you referring: To breast ultrasound? Simple cysts are benign, cysts with solid components are more suspicious. Isoechoic and hypoechoic masses can be benign or malignant. The probability of malignancy depends on other ultrasound features. Some need biopsy, some can be followed or ignored. ...Read more

Complex cyst with small mural nodule what is mural nodule?

Soft tissue: A mural nodule is a small nubbin of solid tissue on the inner wall of a cyst. It is another component of a complex cyst (where is it?). Complex as opposed to simple cysts are at a higher risk for harboring malignancy and so usually require further evaluation. ...Read more

My TPO is 12, my TGab is 1.2, I have a goiter and a nodule on one side with a cyst on the other. I have many hypo symptoms. I was told the chance of me having Hashi's was pretty high, is this true?

Thyroid tests: Your tests are results of antibodies against thyroid peroxidase and thyrogolbulin. If you are hypo (low) thyroid with these positive tests, a DX of Hashi is high. If you are euthyroid (normal tsh, normal T4) it suggests DX of autoimmune thyroid disease. Please be sure you follow up with your endocrinologist. Good luck. ...Read more

Got a 2cm nodule in my left lung. Can it be a hytadid cyst?

Got a 2cm nodule in my left lung. Can it be a hytadid cyst?

Lung nodule: The only way to find out for sure what it is is to do a biopsy. Depending on what the radiologists impression of the lung nodule is, we sometimes elect to do interval or followup imaging to see if the nodule is stable or not. Please discuss with the doctor who ordered the imaging test what the plan of action is. Best of luck. ...Read more

When do cysts and nodules in thyroid need to be investigated further? Blood tests normal levels.

Depending: Generally they are followed through time. Pure thyroid cysts that are small don't really need to be watched. Other nodules should at least have repeat ultrasound to make sure nothing changes. If they have concerning features we biopsy them. ...Read more

Mammogram showed bilateral normal calcs. L. breast 4 sm cysts and 1 nodule. 1mm that couldn't be determined on U/S. Biop. Scheduled. Chance of CA?

Mammogram: If a mass seen on mammogram shows signs such as calcifications, cysts, masses etc that are associated with cancer, a biopsy will be recommended to know for sure. However these findings can also be seen in normal tissue. Only a biopsy will tell for sure. Try to relax for now and I would recommend following through with the biopsy ...Read more

I have thyroid cyst what should I do? I also hv mild nodule n goiter.

Size matters: If the size of your thyroid is causing you symptoms of compression (pressure, pain, difficulty breathing or swallowing), then I would recommend that you have your thyroid removed. If any nodule is > 1cm then it should be biopsied. Otherwise, just observe with yearly or every other year ultrasound. ...Read more

I have several heterogeneous thyroid nodules and cysts with 7mm biggest in size. What does this indicate?

Common. Don't worry: Many people have nodules as they get older. Don't worry about them if they are less than 1cm in size. When and if they get bigger, then we biopsy the solid ones and aspirate the fluid with a needle. ...Read more
