Causes for soft tissue calcification

DYSTROPHIC

Diseased tissue

Normal serum CALCIUM Damaged heart valvesTB LYMPH NODESAtherosclerosisStroma of some tumours<psammoma bodies>

METASTATICNormal tissuesDisorder of calcium metabolismCKDHyperparathyroidismSarcoidosisMilk alkali syndromeHyperVitaminosis D

Commonly seen in kidneys<basement membranes>Lungs<alveolar wallsStomach-fundal glandscornea

Soft tissue calcification

Arterial calcification-aging,primary or secondary hyperparathyroidism,werner’s syndrome.

Venous calcification-thrombosed veins, varicose veins

Nerves- leprosy,neurofibromatosis

Haematomas- cephal haematomas

Page 8: CXR: Multiple calcifications

Metabolic - hyperparathyroidism, vit-D overdose, chronic renal failure

Soft tissue necrosis followed by calcification

Subcutaneous fat necrosis & calcification – ehlers danlos syndrome , christian weber syn

Extensive soft tissue calcification in dermatomyositis – ‘calcinosis universalis’

-TB lymph node,Im injections, snakebites,frost bite,

Tendon – supraspinatus tendon

Diffuse systemic sclerosis

Calcification of tumours- haemangiopericytoma, medullary carcinoma of thyroid, thyroid adenoma

Parasitic calcification-guinea worm, loa loa, cysticercus cellulosae, trichinella spiralis

LIFE CYCLE drinking water infected

With cyclops

Man acquires infection

Larvae released & penetrate the duodenal wall

Larvae Mature&reproduce

Migrates through viscera to subcutaneous tissues

Fertilzed female worm migrates to skin surface

Causes blister ruptures releases larvae

Page 12: CXR: Multiple calcifications

Where stepwells are the source of water supply

Transmission occursEradication is possible

by provision of safe drinking water, control of cyclops,health education

Treatment – Niridazole,Mebendazole,Metronidazole
