    In terms of vascularity, metastases can be hypovascular (in gastric, colonic, pancreatic or ovarian adenocarcinomas) with hypoechoic pattern during arterial phase, and similar during portal venous and late phases, respectively hypervascular (neuroendocrine tumors, malignant melanoma, sarcomas, renal, breast or thyroid tumors) with hyperechoic ...

    In a retrospective review of preoperative CT scan, 35% (135 of 383) of the patients had detectable intrathyroidal calcifications. Among them, 48% had a histopathologically proven thyroid cancer. Calcified nodules had a significantly higher incidence of thyroid cancer and lymph node metastases. The incidence of thyroid cancer among nodules with ...

    en.wikipedia.org/wiki/Thyroid_nodule

    An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic ; surgical excision ( thyroidectomy ), radioiodine therapy , or both may be used.

    Histopathology of NIFTP, H&E stain. [1]Noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) is an indolent thyroid tumor that was previously classified as an encapsulated follicular variant of papillary thyroid carcinoma, [2] necessitating a new classification as it was recognized that encapsulated tumors without invasion have an indolent behavior, [2] and may ...

    Thyroid neoplasm is a neoplasm or tumor of the thyroid. It can be a benign tumor such as thyroid adenoma, [1] or it can be a malignant neoplasm (thyroid cancer), such as papillary, follicular, medullary or anaplastic thyroid cancer. [2] Most patients are 25 to 65 years of age when first diagnosed; women are more affected than men.

    Regular monitoring mainly consists of watching for changes in nodule size and symptoms, and repeat ultrasonography or needle aspiration biopsy if the nodule grows. [8] For patients with benign thyroid adenomata, thyroid lobectomy and isthmusectomy is a sufficient surgical treatment.

    In contrast, tissues with lower echogenicity are called "hypoechoic" and are usually represented with darker colors. Areas that lack echogenicity are called "anechoic" and are usually displayed as completely dark. [1]

    Liver cell adenomatosis is also associated with becoming hepatocellular carcinoma. [11] Like hepatic adenomas, they are diagnosed with imaging and biopsies as needed. Treatment of liver cell adenomatosis is difficult due to the multiple, widespread lesions. Liver imaging should be reviewed to see if it is possible to surgically remove the ...
