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.
larger, broad calcifications (note: these can be seen in medullary thyroid cancer) nodule appears more tall than wide on transverse study "comet tail" artifact as sound waves bounce off intranodular colloid documented progressive increase in size of nodule on ultrasound
A 26-year-old male patient with elevated serum parathyroid hormones and calcium secondary to intra-thyroid parathyroid adenoma. a, b Enhanced axial and coronal CT scan of the neck demonstrate a well-defined hypodense right thyroid nodule (white arrows). c Bone window coronal CT scan shows lytic expansile lesions at the right mandible and left ...
Treatment of a thyroid nodule depends on many things including size of the nodule, age of the patient, the type of thyroid cancer, and whether or not it has spread to other tissues in the body. If the nodule is benign, patients may receive thyroxine therapy to suppress thyroid-stimulating hormone and should be reevaluated in six months. [2]
Several medical conditions – including diabetes, arthritis, Parkinson's disease, multiple sclerosis, neuropathy and thyroid issues – can lead to balancing problems as well. In such cases, an ...
The rare comet, Tsuchinshan-ATLAS will be visible in the night sky throughout the rest of October. This is the best time to see it. ... The comet tail is still too dim to see with your eyes, but ...
The laser ablation of thyroid nodules is performed in day hospital or day-surgery. The patient is placed under mild sedation (the same type of sedation used in an endoscopic examination). A local anesthetic is then applied, and one or two needles (depending on the size of the nodule) placed inside the nodule under ultrasound guidance.
