There are three types of pathologic calcifications: 1) Dystrophic calcification is that which occurs in degenerating and dead tissues. Calcification of the larval stage of tapeworm (cysticercus) is an example of dystrophic calcification.
In our case, the confinement of the calcifications to within and around the walls of brain blood vessels strongly supports the mechanism of dystrophic calcification following primary lead-induced vascular injury.
Tonsillolith is a rare dystrophic calcification as a result of chronic inflammation of the tonsils. In general, it is asymptomatic, more often in older age groups, displaying several shapes and no sex preference (1-10).

It is characterized by dystrophic calcification that develop in the late period following compartment syndrome usually in the lower limb. We present a 66-year-old man who developed calcific myonecrosis 35 years after surgical intervention for compartment syndrome secondary to a gunshot ...
The deposition of mineral salts in dead or degenerating tissues is referred to as dystrophic calcification . In the craniofacial region, these calcifications can occur in the brain (e.g. calcification of choroid plexus, pineal gland, or dura mater), the temporomandibular joint synovial tissue (e.g ...

Peritoneal calcification is caused by two primary mechanisms. Metastatic calcification may be a result of a systemic mineral imbalance in entities such as uremia or hyperparathyroidism, whereas dystrophic calcification may result from tissue injury, aging, or disease, including malignancy .
Its cause is unknown but is thought to be related to the deposition of amyloid within blood vessels of the tunica propnia of the bladder and ureter, producing ischemia and atrophy of this layer with subsequent dystrophic calcification.
