Congenital hemihypertrophy

Introduction to congenital half-sided hypertrophy It is characterized by bone and soft tissue hypertrophy of the lateral limbs, accompanied by vasospasm and venous tumors in this part. Therefore, it is also called vasodilator limb hypertrophy. The exact meaning should be that the body side is fatter than the other side after birth, sometimes it is part The size of the upper or lower limbs is different, sometimes the side of the whole body includes the face, the trunk, the upper and lower limbs, and the internal organs have different sizes, but the structure of the organs on each side of the body is completely normal, called congenital Half of the hypertrophy. basic knowledge The proportion of illness: 0.0001%-0.0003% Susceptible people: no specific population Mode of infection: non-infectious Complications: congenital heart disease scoliosis

Congenital hemifacial hypertrophy

(1) Causes of the disease

There are many causes of hemifacial hypertrophy, such as endocrine abnormalities, vascular abnormalities, lymphoid abnormalities, autonomic dysfunction, abnormal embryonic development, and genetic factors, but the true cause of this disease remains unclear.

(two) pathogenesis

Some scholars believe that hemifacial hypertrophy is related to the unbalanced state of the fetus during the formation process. Some scholars believe that the fertilized egg is divided into two cells of different sizes.

Congenital half-sided hypertrophy prevention

There are no effective preventive measures for this disease.

Congenital half-sided hypertrophy Complications congenital heart disease scoliosis

Congenital heart disease can occur concurrently with pelvic tilt and scoliosis.

Congenital hypertrophy symptoms Common symptoms

Symptoms and signs are often manifested as augmentation of one side of the whole body, asymmetry on both sides of the trunk, upper and lower limbs, asymmetry on both sides of the external genitalia, and internal organs on the same side will also increase, but the organ structure of each side of the body Normal, the limbs are larger than the healthy side, and the bones and ossification centers are also developing rapidly. The clinical symptoms are unequal length of the lower limbs, walking claudication, pelvic tilt and scoliosis, and nearly 10% to 15% of patients have intelligence. Poor development, 50% of patients are accompanied by fingering, multiple fingers, multiple nipples, congenital heart disease.

Congenital hemifacial examination

X-ray examination of the extremities can reveal the left and right limbs, length and length.

Diagnosis and diagnosis of congenital half-sided hypertrophy

Diagnosis is based on scale performance and examination.

Need to be identified with the following conditions:

1. Secondary side hypertrophy, caused by diseases such as blood vessels and lymphatic system.

2. Giant disease caused by hyperfunction of the pituitary gland.

3. One side of the nervous system disease caused by atrophy, it is easy to mistakenly believe that the healthy side is hypertrophy.
