Pineal calcification shift

Introduction Pineal calcification is common in adults and is more likely to occur with increasing age. About 75% of normal adults show pineal calcification on CT scans. The diameter is usually in the range of 3 to 5 mm, but sometimes it may be more extensive. The pineal calcification area is large and displaced, and it appears in children. It should be considered whether there is a possibility of tumor in the pineal region.

Cause

The length of the disease in the pineal region tumor varies depending on the histological type of the tumor, the location (pre-front or posterior) and the size of the volume. The general course of disease is shorter, mostly within 1 year. Clinical manifestations depend on the nature and location of the tumor. There are mainly symptoms of increased intracranial pressure, neurological symptoms and endocrine system symptoms.

Can cause pineal calcification shift.

Brain MRI

When the pineal gland is calcified, calcification shadows are visible on the X-ray film. This shadow has certain value in the diagnosis of intracranial masses. MRI can confirm the diagnosis.

(1) Pineal calcification is greater than 12 mm.

(2) The calcified pineal gland clearly deviates from the midline.

(3) Pineal calcification occurs in children under 10 years of age.

Differential diagnosis

Differential diagnosis of calcification displacement of pineal gland:

1, choroid plexus calcification: choroid plexus calcification is the most common physiological calcification. Choroid plexus calcification rarely occurs in people younger than 3 years of age. The incidence of choroid plexus calcification increases with age, and its incidence can reach more than 75% at 50 years old. Choroid plexus calcification occurs mainly in the lateral ventricles and rarely occurs in the third and fourth ventricles. Calcification can be point-like, diameter greater than 1 cm, round or irregular. Calcification is usually bilaterally symmetrical, but it can also be asymmetrical or only unilateral. For space-occupying lesions such as tumors in the brain, it is sometimes helpful to observe the location of the lesions by observing the presence or absence of displacement and displacement of the calcified choroid plexus. The sputum is located in front of the pineal gland in the back of the third ventricle. After 30 years of age, a 15% brain CT scan can show ankle calcification. Although its shape is more characteristic, it is often mistaken for pineal calcification, and the typical calcification of the ankle is "C" shaped.

2, basal ganglia calcification: normal adult cranial imaging film may accidentally find basal ganglia calcification. Its typical performance is bilateral symmetry, starting with the caudate nucleus head. The calcification can also be asymmetrical, and the globus pallidus, the putamen, and the lateral part of the thalamus can also be involved. Basal ganglia calcification is not common in normal children, but it is more common in adults after age 40. This primary basal ganglia calcification is clearly associated with age.

Physiological calcification has no clinical symptoms and calcification is relatively small. If the calcification is large, accompanied by calculus calcification or calcification in the 30 years old, pathological calcification may be considered.

3, cerebellar dentate calcification: cranial dentate nucleus in the posterior cranial fossa can also appear calcification, but dentate calcification is less common than basal ganglia calcification. It can be accompanied by or without calcification on the screen. Calcification usually has a diffusely fuzzy shape or a small dot shape due to the deposition of calcium around tiny capillaries and the calcification of tiny arteries and venous walls. The significance of calculus calcification is the same as that of basal ganglia, which can be physiological or pathological.

4, dural calcification: dural calcification is common in the elderly, cerebral palsy or cerebellar calcification is easy to identify. Cerebral calcification is mostly linear along the cerebral palsy, and can also be characterized by fusiform calcification in a fusiform or spherical shape.

5, other intracranial calcification: rock bed ligament often appears calcification, on the lateral side of the skull, the appearance of the saddleback and the tip of the rock appears line-like calcification; inter-rock ligaments can also occur calcification, there may be so-called "saddle bridge" Pituitary calcification can be discerned in normal human tissue sections, and simple imaging examination is rarely found; lens calcification can be seen in the elderly, showing an annular shadow in the eyelid.
