What is Exophytic thyroid nodule?
Aim: Exophytic nodule refers to a nodule that sticks out of the normal thyroid boundary/outline. Other definition is a nodule with an acute angle between the lesion and adjacent thyroid capsule. In the literature, one study reported that thyroid nodules with exophytic configuration showed a high malignancy rate.
Can a hypoechoic nodule be cancerous?
Solid masses are hypoechoic and can be cancerous. Cysts 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.
How often are hypoechoic nodules cancerous?
Most of the hyperechoic and isoechoic nodules are benign. The incidence of malignancy is only 4% among solid hyperechoic lesions; it increases to 26% for isoechoic lesions[23].
Can a solid hypoechoic thyroid nodule be benign?
These nodules are widespread, but most are benign. Doctors typically evaluate thyroid nodules using ultrasound scans. Hypoechoic thyroid nodules appear dark relative to the surrounding tissue. These type of nodules are usually solid rather than a fluid-filled lesion.
What percentage of hypoechoic nodules are malignant?
About 2 or 3 in 20 are malignant, or cancerous. Malignant nodules can spread to surrounding tissues and other parts of the body. Solid nodules in your thyroid are more likely to be malignant than fluid-filled nodules, but they’re still rarely cancerous.
What does Exophytic mean?
Exophytic is a descriptive term used by radiologists/pathologists to describe solid organ lesions arising from the outer surface of the organ of origin.
Can a hypoechoic mass be benign?
A hypoechoic mass may be a tumor or abnormal growth. It may be benign or malignant. A benign tumor may grow but it will not spread (metastasize) to other organs. A malignant (cancerous) tumor can spread and invade other parts of the body.
What percentage of hypoechoic breast nodules are malignant?
Irregular hypoechoic breast masses on US are usually considered suspicious BI-RADS category 4, but BI-RADS category 4 lesions are known to have a broad range of malignant rates (3-94%), and these lesions on US vary significantly on histopathological examinations.
What does hypoechoic nodule mean?
A hypoechoic nodule, sometimes called a hypoechoic lesion, on the thyroid is a mass that appears darker on the ultrasound than the surrounding tissue. This often indicates that a nodule is full of solid, rather than liquid, components.
What does Exophytic Tumour mean?
Pathologists use the term exophytic to describe an abnormal growth that sticks out from the surface of a tissue. This pattern of growth can be seen when the tissue is examined under a microscope. Pathologists use the word exophytic to describe both benign (non-cancerous) growths and malignant tumours (cancers).
What is Exophytic mass?
Exophytic hepatic mass or tumor is a lesion which predominantly lies outside the margins of liver but originates from within the liver.
What does hypoechoic mass in the kidney mean?
A hypoechoic mass is tissue in the body that’s more dense or solid than usual. This term is used to describe what is seen on an ultrasound scan. Ultrasound uses sound waves that are absorbed by or bounce off of tissues, organs, and muscles.
Is hypoechoic good or bad?
A hypoechoic breast mass may be benign, as in the case of a non-cancerous tumor called a fibroadenoma. This appears on an ultrasound scan as a hypoechoic mass with smooth edges. Fibroadenomas are common in young women and may sometimes disappear by themselves, so they are usually only removed if they are large or increasing in size.
Does hypoechoic mean cancer?
A hypoechoic lesion is an abnormal area that can be seen during an ultrasound examination because it is darker than the surrounding tissue. Such abnormalities can develop anywhere in the body and do not necessarily indicate cancer.
What is a hypoechoic mass in the thyroid?
A hypoechoic nodule, sometimes called a hypoechoic lesion, on the thyroid is a mass that appears darker on the ultrasound than the surrounding tissue. This often indicates that a nodule is full of solid, rather than liquid, components.
What is the significance of thyroid nodule?
The Significance of Thyroid Nodules. A thyroid nodule is an abnormal growth of thyroid cells that create a small lump in the thyroid gland. Oftentimes they go unnoticed, especially if they are small.
