Features of benign lesion are: hyperechoic, having coarse, dysmorphic or curvilinear calcifications, comet tail artifact (reflection of a highly calcified object), absence of blood flow in the nodule, and presence of cystic (fluid-filled) nodule. However, the presence of solitary or multiple nodules is not a good predictor of malignancy.
When horizontal x-ray beams, commonly used in lateral projections, are used to image the breast, the fluid inside the cysts, such as milk of calcium, is imaged tangentially. [2] This technique often produces linear or curvilinear patterns of calcification. In some cases, a semilunar shape may appear, which is why this sign is called "teacup sign."
Thyroid calcifications on a CT scan can be seen in both benign and malignant thyroid lesions. Sonographic examination of the thyroid can differentiate between micro-calcifications, which are highly associated with papillary thyroid carcinoma, and eggshell calcifications, which favour a benign process such as colloid cysts (Figs. 1 and 2). In a ...
The photo shows the characteristic dark color of an oncocytoma, a rare type of benign neoplasm, at the left side of the image (the normal lobulated salivary gland tissue is to the right). An salivary gland oncocytoma (also known as an oxyphilic adenoma ) is a well-circumscribed, benign neoplastic growth comprising about one percent of all ...
An adnexal mass is a significant finding that often indicates ovarian cancer, especially if it is fixed, nodular, irregular, solid, and/or bilateral. 13–21% of adnexal masses are caused by malignancy; however, there are other benign causes of adnexal masses, including ovarian follicular cyst, leiomyoma, endometriosis, ectopic pregnancy ...
Calcium buildup in breast arteries detected by mammography usually is not a sign of cancer, but it might indicate a higher risk for heart disease, two research teams reported at the Menopause ...
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [1] [2] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
Benign tumors of bone can be similar macroscopically and require a combination of a clinical history with cytogenetic, molecular, and radiologic tests for diagnosis. [23] Three common forms of benign bone tumors with are giant cell tumor of bone, osteochondroma, and enchondroma; other forms of benign bone tumors exist but may be less prevalent.
