An incidentally discovered colloid nodule with calcification, shown on CT scan of a 58-year-old female patient. a Non-enhanced axial CT scan of the neck demonstrates a coarse calcification at the left thyroid inferior pole. b Sagittal grey scale ultrasound of the thyroid demonstrates a heterogeneous nodule with a predominant cystic component.
Stippled epiphyses is a pattern of focal bone calcification. The presence of abnormal punctate (speckled, dot-like) calcifications in one or more epiphyses. It is seen in chondrodysplasia punctata and in Keutel syndrome. It is also caused by use of warfarin, alcohol, and in hypothyroidism. [1]
Suspicious findings in a nodule are hypoechoic, ill-defined margins, absence of peripheral halo or irregular margin, fine, punctate microcalcifications, presence of solid nodule, high levels of irregular blood flow within the nodule [11] or "taller-than-wide sign" (anterior-posterior diameter is greater than transverse diameter of a nodule).
The first step in diagnosing a thyroid neoplasm is a physical exam of the neck area. If any abnormalities exist, a doctor needs to be consulted. A family doctor may conduct blood tests, an ultrasound , and nuclear scan as steps to a diagnosis.
Dystrophic calcification (DC) is the calcification occurring in degenerated or necrotic tissue, as in hyalinized scars, degenerated foci in leiomyomas, and caseous nodules. This occurs as a reaction to tissue damage, [ 1 ] including as a consequence of medical device implantation.
Section of human adrenal gland under the microscope, showing its different layers. From the surface to the center: zona glomerulosa, zona fasciculata, zona reticularis, medulla. In the medulla, the central adrenomedullary vein is visible. The adrenal cortex is the outer region and also the largest part of an adrenal gland.
Micromelia, polydactyly and ectopic calcification, or the built up of calcium in the soft tissues of the body, may all occur. Eighty to ninety nine percent of effected individuals will have abnormally ossified vertebrae, abnormal pelvis bone ossification, anterior rib punctate calcifications and brachydactyly. [7]
Ectopic calcification is a pathologic deposition of calcium salts in tissues or bone growth in soft tissues. This can be a symptom of hyperphosphatemia . Formation of osseous tissue in soft tissues such as the lungs, eyes, arteries, or other organs is known as ectopic calcification , dystrophic calcification , or ectopic ossification .
