What Are the Common Causes of Liver Scarring?

Calcification (calcification) refers to the use of B- or CT images of an organ that appears like a stone with strong echo or high-density image of calcium deposits. Lung calcification, liver calcification, prostate calcification, and kidney calcification are common.

Basic Information

English name: calcification
Common locations: Lungs, liver, prostate, kidneys, etc.

Common causes: Fibrotic scars caused by inflammation and tuberculosis, or after local tissue necrosis
Contagious: no

Causes of calcification and common diseases

Calcified lesions are generally caused by inflammation and tuberculosis, and are formed by the deposition of calcium salts in local tissues. For example, pulmonary tuberculosis can form pulmonary calcified lesions after curing. It may also be fibrotic scars formed after local tissue necrosis, such as intra-liver calcifications. Calcifications are common in diseases such as intervertebral disc calcification, histoplasmosis, lipoidoid deposition, soft tissue tumors of the chest wall, tuberculosis, cerebral pulmonary fluke disease, alkaline calcium phosphate deposits, and intracranial cavernous hemangioma.

Differential diagnosis of calcification

Pineal calcification

It is located about 3cm above and behind the upper end of the saddle. Adults have a development rate of 40% and rarely occur under the age of 10. Its position is relatively constant and it is a good positioning mark.

2. Cerebral sickle calcification

It is located at the midline in the upright position, and is band-shaped or triangular, with an appearance rate of about 10%.

3. Calcification of the interbedicular ligament

The calcification of the ligament between the anterior and posterior bed of the saddle makes the saddle a "bridge shape".

4. Calcification of lateral ventricle choroid

Irregular shadows within 2.5 cm of the center line, the occurrence rate is less than 0.5%.

5. Other

Localized calcifications of the basal ganglia, dentate nucleus of the cerebellum, siphon of the internal carotid artery, cerebellar tentacles, rock bed ligaments, and dura mater were also seen in rare cases.
