Direct compression of adrenal glands and acute intravenous pressure rise due to compression of the inferior vena cava are the two proposed mechanisms of traumatic adrenal gland injury. [ 1 ] Non-traumatic adrenal hemorrhage is an atypical type, which can be further categorised as acute stress and neonatal stress, anti-phospholipid antibody ...
An ultrasound examination shows accumulation of chalky material (calcification) in the adrenal gland in about half of infants with LAL-D. [2] [4] Complications of LAL-D progress over time, eventually leading to life-threatening problems such as extremely low levels of circulating red blood cells (severe anemia), liver dysfunction or failure ...
Adrenal gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. [1] Your body produces too much or too little of one or more hormones when you have an adrenal gland dysfunction. The type of issue you have and the degree to which it affects your body's hormone levels determine the symptoms.
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]
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.
It may cause acute kidney injury. It is now more commonly used to describe diffuse, fine, renal parenchymal calcification in radiology. [2] It is caused by multiple different conditions and is determined by progressive kidney dysfunction. These outlines eventually come together to form a dense mass. [3]
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.
One of the principal causes of arterial stiffening with age is vascular calcification. Vascular calcification is the deposition of mineral in the form of calcium phosphate salts in the smooth muscle-rich medial layer of large arteries including the aorta. DNA damage, especially oxidative DNA damage, causes accelerated vascular calcification. [11]
