Fissure widening

Introduction Refers to organ texture, such as cerebral sulcus, the longitudinal division of the brain divides the brain into two hemispheres, the brain is divided into large divisions, and the cerebellum. Brain atrophy can be seen to deepen the sulcus. The widening of the sulcus is a disease in the tissue. The tongue is usually considered to be a congenital malformation caused by dysplasia of the tongue. As the body grows, the fissures are deepened and widened. This is also the reason for the high incidence of adults. It is more common in the elderly, according to statistics. The above can reach 14.3%. However, diseases such as edema, congestion, muscle atrophy, and excessive proliferation of epithelial spikes may cause the occurrence of grooved tongue.

Cause

The widening of cerebral sulcus can be caused by brain diseases such as brain atrophy, and can also be caused by brain trauma.

Gully tongue is usually considered to be a congenital malformation caused by dysplasia of the tongue. As the body grows, the fissures are deepened and widened. This is also the reason for the high incidence of adults. It is more common in the elderly, according to statistics. Over 70 years old can reach 14.3%. Some grooved tongues occur in the day after tomorrow. The reason is not clear, but all diseases such as edema, congestion, muscle atrophy and excessive proliferation of epithelial spikes may cause the groove tongue to occur.

The characteristic of the cracked tongue is that a deep groove is formed on the back of the tongue. The direction of the groove is like a vein, and some are like a brain pattern. Therefore, it has the name of a leaf vein and a brain tongue. Generally, there is no self-conscious symptom. There is a deep groove in the back of the tongue. The number of normal nipple fissures is not necessarily. The sulcus is easy to store dirt and cause congestion and edema. In case of irritating food, there is mild discomfort or tingling. The reason why the tongue cracking patient is distressed is that the tongue is not easy to clean, which leads to Infection is uncomfortable.

Brain atrophy can be found by reduction of brain tissue volume and ventricular enlargement by imaging examinations such as CT and MR (nuclear magnetic resonance). The atrophy of the brain showed an increase in the gap between the cerebral cortex and the skull plate. The cerebral sulcus widened and deepened, the cerebral palsy flattened, the lateral ventricle and the third ventricle expanded, and the density around the anterior and posterior horn of the lateral ventricle decreased. When the cerebellum is atrophic, the cerebellar texture is coarse.

Differential diagnosis

Isolated mild lateral ventricle widening refers to cases in which no abnormal findings are found in the prenatal system. About 10% of the isolated mild lateral ventricle widened fetuses are chromosomal abnormalities, the most common of which are the trisomy 21, and the viral infection during pregnancy, especially cytomegalovirus infection, often leads to isolated lateral ventricle widening and ventricles. Abnormal performance such as mixed echoes.

Severe ventricle widening (ventricle width 15 mm, also known as hydrocephalus) refers to excessive accumulation of cerebrospinal fluid in the ventricular system, dilatation of the lateral ventricle system, increased pressure, and hypertrophy of the ventricles. Generally, the lateral ventricle triangle area is widened by 1.5 cm, and the ventricle is enlarged, and the wider the degree, the heavier. If the triangle is 1.2 to 1.4 cm wide and the choroid plexus is more than 50% in the ventricle, it is generally considered normal. If the choroid plexus shrinks and is suspended, it is considered that there is hydrocephalus.

Mild lateral ventricle widening was defined as lateral ventricle diameter 10 mm, and 15 mm. The lateral ventricle diameter <10 mm is considered to be in the normal physiological range.
